    Holes would make it dip before, not after. 

     


    Yes, and that doesn’t matter.

     

    The dip before leads to the dip from the original point of aim after the gun is done recoiling.  It’s just a more complicated way of explaining the same thing.

    Tanfoglio’s are not as nice from a quality of parts standpoint, but they are nicer from a function and engineering standpoint. 

     

    I think it’s funny when some say people like JJ and Grauffel could win open with a different gun - because they didn’t and don’t.   JJ didn’t win Nationals until he switched to the Tanfo.  Eric won everything open with a Tanfo.  Even the most recent Asian competition where he was sponsored by CZ.

     

    Until we can get Eric and JJ to come on here and say otherwise (I don’t think they will, judging from the last time I spoke with them at the 2012ish nationals) - I’m sure the v-porting Is much of the reason why they chose to use the Tanfo.


    Physics does work that way.  The lower pressure area on the sides where the gas is vectored causes a high pressure area in the top and bottom parts of the barrel.  That stabilizes the gun horizontally.  This is simple rocket science.

     

    The same way that a low pressure area on top of the barrel will cause a high pressure area on the bottom, and cause the barrel to go down.

    My $.02 is if there was some combination of holes, comp size, shape and layout that was actually better than the others, all open guns would be made that way but they are not. Look at the Super Squad there are a variety of comp designs with and without holes on various lengths of bull, hybrid and sleeved barrels with slides of varying weights running 9mm and 38s loaded with a variety of powders and bullet weights. 

     


     

    Just curious, do you know if any members of the super squad at the 2019 Open Nats used a gun without popple holes?  If so, was it a full size or shorter?

     

    In my experience, popple holes do what comps do.  But, they do it without putting weight further from the shooter (weight which makes the gun harder to transition).  That’s why I like the v12 Tanfo.

     

    For the OP, the best way to find out what number and size of popples is most effective for your comp is to go one-at-a-time.  I know this is too inconvenient for most people, but the last thing we want is a gun that dips after muzzle flip with every shot no matter which recoil spring you use.

     

    We want the perfect return to center every time.

     

    Grauffel, at points, has used a Gold Tanfo with a single larger hole oriented vertically near the comp.

     

    The current Gold design uses a staggered setup, but it does so with angle of popple holes instead of size.  The eight closest to the breech use a forward canted design.  The 4 at the comp are perpendicular to the muzzle.

     

    In addition to the effect of size on popple holes, the smallest changes to recoil occur when the holes are canted more toward the muzzle and when the holes are closest to the muzzle.  The largest changes occur when the holes are reverse canted (toward the shooter) and the holes are closest to the breech.

     

    So, if the gun returns just a little bit high, consistently, when you use the same grip each time - maybe a small hole or two near the end of the compensator is appropriate.  If it seems like you regularly throw shots over the target with fast splits, maybe you need some bigger holes closer to the breech.  It’s all a balancing act.

     

    Oh, and also, for horizontal return (the dot moving straight up and down every shot), the holes need to be pointed more to the sides than to the top.  For vertical return (less movement up), they need to point to the top.

     

    For me and for a lot of other people, that horizontal return is more beneficial than the vertical return.  Again, why I prefer the v12 instead of, as an example, the vertical holes on most 2011s.

     

    Also cool about the horizontal return - you can’t over compensate.  As long as the holes are balanced, your dot will just track straighter and straighter.

     

    Now then, all of this is at your own risk.  I’m not a gunsmith and I recommend you only have a licensed and insured gunsmith do this work for you.

     

    But all that being said, if I were having popple holes done - I’d use a V config every time.  Akai likes at least 4 in his open guns, fairly close to the breech in comparison to most 2011s.  Does he still post on these forums?

  4. Honestly, I’ve thought about this for a while.

     

    if the barrel had failed due to normal use (it failed along it’s weakest point),  the separation of the barrel in and of itself could have caused the right circumstance for the rest of the powder to detonate, causing damage to the slide.

     

    I can’t honestly say I know what happened here and I think we should give the OP the benefit of the doubt.

    It can’t be same for AKAI gun and SVI gun.

    i use 1 time Borrowed ammo in my SV open gun . JJ Ragazza give me to I try his Armscor ammo prepared for his Tanfoglio gun. It’s super hot in my gun , give me lot of pressure in my gun. 
    for SV open gun is best VV 3N38 powder and 125 gr bullet.


    Tanfo’s generally have shorter chambers than 2011s.

     

    The Akai and SVI use generally the same formats and interchangeable ammo is very possible.

  6. Most squibs cause a higher localized pressure peak which tends to make extreme bulging in one area very obvious.

     

    This still looks more like a detonation event to me given how spaced out the damage is.  The barrel couldn’t contain the pressure at its weakest point as opposed to wherever the squib would have forced the barrel to contain the pressure.  Intermittent lack of neck tension could have put a bullet in a very unusual proximity, causing just the unique condition necessary.  

     

    Lines up with the primers and the barrel cross section more so than a squib in my experience, but I obviously can’t rule out anything with the information we have.

    I also understand this barrel make it looks more like a squib because of the lighter area where the powder residue and finish appears to have been blown off just before the cracked opening.  However, I still don’t think squib is the most likely explanation.

    You didn't provide any new information.
     


    Again, more misinformation.  Show me anywhere that lists the regular production version price.

     

    I can see you are getting offended.  I am not bothered by your offense.  I am bothered by the misinformation you continue to spread on what should be a place for accurate, well-informed knowledge.

    What misinformation? 


    1.  That Lancer in their videos was implying wait for regular production version of a year after the signature edition.  They are currently anticipating 6 months after the signature release in any available video that speaks to it.  BUT, it is strictly a business decision on their part, which is why no one really knows.  They will obviously want to sell all of the signature edition first.

    2.  The way the gas system operates.

     

    3.  That there are no videos of the compensators, further implying that they don’t exist.

    it's striker?

      maybe for aliens 😀


    Again, no. 
     

    Someone else compared it to a striker driven gun.

     

    Please, for the sake of the entire firearm’s community, I strongly encourage everyone to take the time to read and do proper research.

    All but 2 of that brass is ok....but those two had some sort of overpressure issues. It could be bullet setback, it could be a larger than normal charge. The ones in question do not appear to be flattened, and if the others came from the same batch, I would expect them to show the same signs, if the cause was bullet setback, I would expect to see them all like that.


    If the bullet setback is intermittent (definitely possible depending on the sizing die with .355 brass), I would expect the primers to look exactly like that in a random sample.

    Lancer themselves have said there's a good chance there won't be anything until 2021 in videos from SHOT Show.
     


    Has anyone seen it? There are no videos on the internet of it. Also, doesn't the gas system send the slide forward and not dampen the slide going to the rear? Pretty sure I saw that mentioned in one of the videos. Not saying it won't cycle open guns though, but I don't think if it will actually soften the recoil at all.

    Should be interesting. At 42-43 oz (was something like this), I guess it would be about the same weight as a 2011 with a polymer or aluminum grip. So, maybe not ideal, but not terrible.
     


    Yeah, that's because it uses a different design, which I believe is actually SAO in nature, which should disqualify it from Production & Carry Optics... it seems like they found a loophole in IPSC. Will be interesting to see what USPSA does.

     


    Agree with this. Also kinda negates the main advantage of the gun. Would be better suited to being sold as an Open gun where it won't get caught up in restrictions like this, probably.
     


    I think USPSA would sooner change the rules to clarify them further & disallow this gun or require the same mount as IPSC. Other competitors would quickly complain about the unfair advantage of the fixed optic, like what happened in IPSC.


    I'm still interested but too many unknowns to commit to it for that kind of money. Need to see what divisions it will be allowed in, what parts will actually be available, how quickly problems are taken care of, etc.


     

    Again, a lot of misinformation.  Please do research before posting.

     

     

     

  12. That’s a pretty catastrophic failure.  I’m around a lot of Infinitys in Texas (SVI’s home state) and I haven’t seen anything like that.  


    Are you guys loading your own ammo in Chile?  What powder?  Some of the international powders can be very inconsistent.

     

    Schaet, you just barely beat me to it.  Now it looks like I copied your first line instead of you copying mine.  Not cool. 😄

    Yep.  Did what you did along with the Patriot Defense bolo and Titan hammer.  Also, when I added extended mag bases, went nose dive crazy.   And grams guts may have had something to do with the issue.  Took a dremel grinder tip and "ramped" the front control ribs inside the tubes at the bottom and solved that.  The "bump" was just too abrupt I guess.  Did one tube on both front and rear control ribs and it worked just as good.  Fwiw......


     

    I haven’t heard of this.  I will try to find the “control ribs” this evening.  I’m guessing they are on Mec Gar mags?  Ironically, I haven’t had any nose dive issues since I turned in the Feed lips (the .340 was narrower than factory to get it to work, believe it or not - opposite the experience I’ve had with 2011’s). But it would still be nice to make the mags run smoother.

     

    Thanks

  14. Let me try to clear some things up. 

     

    First, I don't work for Lancer, this is just some info I've gathered.  

     

    $5k for the initial signature run.  $3500 for the regular production afterward (the regular production will not include the red dot and a few other things).  I don't expect a year wait after the signature run but I have no good info on release.  

     

    Yes, there is already a compensator for the gun.  It supposedly makes a great open division platform.  Makes sense with the innovative gas system which supposedly self regulates for hotter loads. 

     

    Also, the fixed barrel and optic mount from the factory - you're telling me I can have an extremely accurate gas operated open gun with whatever optic I choose for about $4k?  Sounds pretty good.  

     

    The best striker fired triggers on the market will not be as good as the trigger on this gun.  

     

    My sources at the shot show have already left, so I don't think I can get any additional info for anyone.   

     

    Either way, let's wait and see what happens.  The company already seems a lot more responsive than the miserable customer service nightmare that Hudson was. 

  15. Tanfo performs better.  I've shot both.  JJ won nationals with the v12 Gold.  Eric won EVERYTHING with the v12 gold.

     

    The v-ports are just so much better for straight up and down tracking. I've spoke with both JJ and Eric about that and we all get the same impression in terms of v-ports.  I haven't talked to either of them in a long time, but I'd be real curious where they are in terms of porting on their Berettas or CZs. It may just be impractical for Beretta or CZ to accomplish on their handguns.  

     

    To make my most recent Tanfo Gold Team run, I had to increase extractor tension, buy Mec Gar Mags, tune the feed lips to .340", polish the underside of the slide and round off the front underside edge of the breech face.  I also made a few other personal adjustments.

     

    Not too much to do if someone tells you what to do straight off;  but, a whole lot of trouble shooting if you have to figure out what I just told you.

     

    I'm not a gunsmith and I'm not recommending you do any of the things I listed - perform at your own risk.   

  16. I'm about 7000 rounds in now.  Got a 100% on a classifier the other day.  

     

    Getting the ejection correct with low optic mounts is a bear on this thing as a result of the higher frame and inconsistent extractor tension.  Not too happy with how much testing I've had to do, but I'm pretty sure I have a reliable piece at this point.  

     

    I went to a full Unica setup on the trigger.  After about 5,000 rounds with the polished and adjusted stock setup - I started to get some hammer follow.  I resurfaced that sear and it fixed it, probably for another 5,000 rounds, but I'd rather just have a perfect factory engagement that still yields about a 2.5 lb pull and keep the stock trigger parts as a backup.  Also, the Unica hammer legs are lower, so they enable the shorter post travel on the trigger with no work.  

     

    One thing I did do was shorten the reset leg on the sear in order to reduce the reset length.  Worked perfectly. As others have reported, a few coils from the main spring had to be removed with the Unica hammer in order to prevent spring bind.

     

    Most importantly - barrel lugs still look perfect.  What a relief.   Gun is as good as any I've ever shot when using Shooter's World Major Powder (most of my open guns have been 38 super/comp, this one is 9 major).

     

     

     

    Also, almost forgot to mention - I don't recommend the IPSCAlex RTS mount.  Anyone who is able to get their Tanfo working with where that mount sits is practicing black magic or something.  The mount is so far back and so close to the slide, the brass would have to eject perfectly through just the right angle in the ejection port every single time in order to work.  I tried moving it forward one screw hole in order to give the ejection some leeway - and then the screws weren't spaced far enough apart to prevent the mount from rotating when I was also using a thumb rest (even when torqued past spec).  On top of it, the whole mount is too thin and flimsy.  Just don't get it.
