    Just checked the rules (2019) and no such thing appears that I can see. The term "chamber safety flag"appears 7 times one of those is a description in the Glossary - Chamber Safety Flag .......... A brightly colored device, no part of which resembles a round or any part thereof. The flag must be incapable of being inserted into a firearm which has a loaded chamber and must, while fitted, prevent a round from being inserted into the chamber. The flag must have an integral tab or ribbon clearly protruding from the firearm.

     

    About the only thing that might rule one out would be the ribbon but if that's attached to the mag it would protrude from the magwell.

    I might chase it up with my National NROI

     

    I know this is an older thread, but the bold above would indicate a mag block is NOT allowed.

    The problem is the mag catch on Glock and several other mags.  The catch is only a depression, not cut through as on MBX Glock mags.  The additional weight of the metal extension and the extra 10 rounds is too much for your mag catch.  You insert the mag, load and fire.  The extra weight and the recoil jostles the mag  enough the next round won't feed.  If you hold the mag in, it will feed.  After you do this for 3-4 rounds, the mag is light enough to be retained in position by your mag catch.

     

    You cannot solve this problem if using Glock 33-round mags as your base.  SMS mags won't work either.  Don't know about ETS 33-round mags.  I had exactly the same problem on my PCC.  I sold the mags and extensions and bought 40-round ETS mags.  They work 100%.

    Thats interesting. I guess my JP-5 didn't get that memo.

    ETS mags are the only mags to give me an issue in any PCC, and then its only when they are seemingly trying to digest a single grain of sand.

     

    Prior to getting my JP-5 my AR9 had the issue of not feeding the first couple of rounds after I installed the TTI +10. it was the transition that was easily fixed. The 33rd with blended transition with the TTI +10's work perfectly in my JP-5.

  3. I personally would change it. I have found theres a balance between too grippy and too slippery. I don't care for a stock or pistol grip that does not allow a degree of movement when you need it. The really grippy ones can cost you as much time as a really slippery one. Texture is the important factor here, especially on grips, as is the type of rubber compound on a butt pad. I prefer magpul stocks as I find their butt pads grippy, but not overly so. Many of the grips and gel pads on the market are overly grippy. Hogues products for example, are generally too grippy for my tastes.

  4. shooter error.

     

    You over inserted that mag by aggressively stuffing it in the Magwell with the bolt back. Nothing wrong with the mag.

     

    If you don't want to get in the habit of changing mags before your out of ammo get gen3 Mags that have the over insertion tab to prevent this.

  5. Many moons ago I had a scope with huge uncapped turrets. The darn things seemed to turn on their own. Lol I took a piece of bicycle inner tube about 2" wide, cut a hole just the right size for the elevation turret to stick threw and it covered the other turrets. It required un-mounting the scope, but that's not a big deal. to get to the other turrets you could just peel it back, make an adjustment and re position it. easy to peek under to be sure you didn't move one, the pressure from the tubing makes it pretty much impossible to bump one out of position. Worked for me.

    Anyone know of any handguard wrap or grip tape? I’ve seen some people with them, but I can’t find anything about them online

     

    Are you trying to improve grip or keep heat away from your hand?

     

    I needed heat protection from a suppressor that extends way down into the hand guard. Burnproof gear made me this custom cover. It is not as slippery as the standard hand guard, but its not grippy like some of the other options. But it really does keep the heat away.

    Do you know the weight of the scheel gen2 buffer?

     

    JP-5 buffer = 4.8 oz

    Scheel Gen 2 = 6.2 oz

    TACCOM = 7.0 oz 

    KAW 7.5 = 7.8 oz

     

    One interesting observation is in my 4 PCC's The softest shooting to the least soft shooting runs straight along with the weights of the buffers. Meaning lightest buffer is softest and so forth to the least soft being the heaviest. I listed them in that order also. All with the same ammo.

  8. I have the scheel gen 2 in one PCC and I also have a JP-5. The scheel is softer than the TACCOM set up I had in it prior, but I really don't care for the Scheel as the soft spring it comes with is right on the edge of reliability. After just a few hundred rounds it gets really sluggish. 

     

    The JP-5.......yeah, worth saving for. The scheel and taccom are not even in the same league.

    No, sorry I meant to say starting with a shotgun that is not fully loaded does not make sense to me.  Making the shotgun start position with the shotgun fully loaded and minimizing rounds used during a given stage means more shooting and less of a loading race. 

     

    Completely agree, thanks for clarifying.

    I can see this for sure.  I never understood the reason for starting with a fully loaded Shot gun as well regardless of the division.  Make some tweaks it might resurrect the sport a bit.  

    So, you feel forcing the shooter to load an empty or down loaded shotgun will resurrect 3-gun? ( I know, "among other tweaks") This seems counter to why a lot of folks don't like the shotgun. The shotgun complaints I hear most are how the shotgun portion is just a loading/reloading race.

    They do not stake the castle nut? Understand this is a competition gun but still.

     

    If its important to you, its easy to do. Far from necessary on a PCC. I prefer they not be staked.  Not that its hard to remove when necessary, but its ugly. I generally locktite mine and have yet to have one loosen up.

     

    At any rate, mine came staked from JP.

    Honestly, on the hand guard to get questions on social. It's funny that people don't think you can use the rail, much less an index, to aim at the distances you're using an offset most of the time. 

    Running a holo like a UH-1 made me realize I don't really use the offset all that much with such a big window. 

     

    I been playing these games a long time.....I'm tying to wrap my head around a second offset dot. Why ya all doin that??

  13. I have and it works. I didn't even know about this thread when I started another thread on the same subject as tt350'z did. I actually couldn't get the rails to squeeze in a vice. I had to carefully hammer them down to the dimension I wanted then I had to refit the rails to the slide with a file. Like His mine grouped like 6-8 inches at 15 yards. Totally unacceptable. When I was done groups were under 2" at 15 yds, and no flyers. It's not a barrel to slide issue.

     

    I just don't understand why SIG uses a stamped pos part for the fcu housing on the P320. They at least got it right with the P365 and machine a more precise housing for it. Both of my P365's were far more accurate than my P320.

  14. Many moons ago when I got my first DPMS TAC20 it exhibited this characteristic. Didn't want to reliably chamber anything. They had some arm length disclaimer about just about any and all foreign made 7.62x51 not being any good for their chambers, but I ultimately found it was just really sharp points on the barrel extension in the vicinity of the machined feed ramp, where the bolt lugs run thru and then lock. It was very evident by some judicious scratches and gauges in the brass of rounds I tried to chamber. These burrs were just grabbing the soft brass and putting the breaks on. A small file and a little patience I had the barrel extension nicely smoothed out. That thing would chamber just about anything after that.

     

    Hope this helps.

    The FCU is the firearm...serialized part...so..ya.

     

    Any Manufacturer with a manufacturing FFL could make one on a CNC machine. Which is pretty much any shop of many around the country who pump out AR15 lowers. Its no different than that. I know of at least one who has branched in to other products because AR lower sales have slowed, Im sure theres others. I hope someone will step up and produce such a part.

    @mpeltierCongratulations on the results of your experimentation!  Definitely proved what results can be had.

     

    I remembered seeing a similar post a while back that also showed what could be done by bringing the FCU rails down to get rid of that excessive play:

     

     

    Would definitely jump on the opportunity to purchase a precision CNC machined FCU to improve the slide to FCU fit!

     

    Thanks for sharing your results!

     

    👍

     

    Your welcome.

     

    The thing that really puzzles me is that the P365 FCU uses a machined housing instead of a stamped piece. And the rails and tolerances are much better on both my P365's than on the 3 P320's I have. My P365XL is also as accurate as my X5 is now and more accurate than my other P320's. 

     

    It's NOT so much a barrel/slide issue. It's the FCU housing.

    Man I forgot I had a gen 1 M&P Pro. That thing had such terrible accuracy as well. Swore off M&P’s to this day because of that gun.

     

    I had one too. When I first shot the SIG, I thought, here we go agin.....Just like the original M&P. an Apex bbl fixed that M&P. I no longer have that gun but do have a 9mm and .40sw M&P 2.0 and they are very accurate out of the box.

    stock 320s have a LOT of vertical clearance from the locking lug on the barrel and the locking pin in the FCU,  I have welded up and re-machined a few barrels on friends guns and most have needed +0.020" to get a decent lockup. all have reported better accuracy specifically the lack of unexpected flyers 

     

     

     

    When I first started analyzing the issues I thought my barrel had some play in the slide by pushing down on it. After careful inspection of this it was actually pushing the slide back slightly when I did this witch resulted in the barrel starting to cam downward. Wasn't anything wrong there. But all that free vertical play, more up front than in the back just struck me as wrong. After some careful measuring I was pretty sure it was a tolerance issue with the FCU shell as it was stamped at the factory. These stamped FCU housings are not the most precise pieces and rely on the dies that strike them for their tolerances. I think SIG needs new dies. Or better yet offer a CNC machined FCU to better control and tighten this up. The FCU housing is amazingly simple. A good CNC machine could spit one out in no time.
