Finally read the FAQs

Finally read the FAQs (3/11)

  1. No, I have not. You are correct, no actual hands on experience with 2011s until now. I have done a good bit of watching/reading about the platform prior to ordering and while waiting for the gun to arrive. If nothing else, I concluded that a pistolsmith or open gun owner of any experience level should (hopefully) start with basic function checks prior to live fire, particularly with 9 major. I had a pretty bad KB in my PCC last summer from bullet set back and don't want to go there again. I plan to shoot the gun once I get that resolved. Just ordered one for my 9 major powder measurer, hopefully it eliminates the set back.
  2. Update: I took a little more off the left side safety, it's pretty comfortable if I don't try to grip the gun super high. Still sorting through getting a good grip that isn't approaching slide bite territory and being able to run/ride the safety. Mags: I have 4-170mm and 1-140mm Gen 2 STI tubes. Some with Grams guts, some with TTI. They sat fully loaded all week so I emptied them out today and gave them a once over. I watched the Atlas mag tuning videos on YouTube and ended up making a few small adjustments to the feed lips. Most were already within their specs. I couldn't bring my self to squeeze the bodies down to .560" at 1 inch down like they suggest. That was anywhere between .040-.050" of squeeze required depending on the tube. I called it good around .590", not much luck getting good repeatable measurements in that area either. All mags feed great using dummy rounds loaded up to 1.165" I cycled the gun with as many as 15 in the tube. Ejection was consistent with the exception of the 2nd and 3rd to last rounds in a few of the mags. Basically straight up out of the gun rather than 3:00ish like the rest. The rounds are not nosed up when sitting in the mags and contact the feed ramp pretty low. When removing a loaded magazine after cycling, the top round is consistently pulled out about 1/4". Not sure if this is bad, but it has not caused any issues with mags dropping free to this point. Bullet set-back: I'm getting anywhere between .010-.040" of set back with a good hard lean on the reloading bench. I even used a bullet comparator to make sure I wasn't just measuring deformation of the hollow point. I didn't measure any change in length when hand cycling rounds through the gun though. Press set up as follows- LnL AP Case activated powder measurer with Hornady .355 powder funnel set with just enough flare to hold a bullet stable during indexing. Lee U die MBF die with MagP Lee FCD Bullets are PD 115gr V2 (haven't shot any yet, but they look nice) loaded to 1.165" "Crimp" at .377" to remove flare mixed head stamp brass I have a theory: Any amount of the PTX funnel that goes deeper into the case than the bullet when seated to 1.165" oal negates the under sizing done by the U die and allows a lower tension area for the bullet to set back. There is about .130' of bullet in the case at 1.165". A case sized with the U die will only go onto the ptx funnel by hand about .065". To get the flare required to stabilize the bullet during indexing, the powder funnel goes full depth( about .300") into the case. The funnel is somewhat tapered otherwise the set back numbers would probably be more. I use the DAA funnel in my other powder measurer for CO loads. The funnel is a little shorter and has a different profile that might be better for this application, but I still think it will have a similar result. That being said, there are tons of people out there loading 9 major without this problem so I'm not really sure where to go from here. Thoughts? Thanks
  3. Thanks for the input everyone. I've learned a lot over the last week or so. The first picture in this thread is the as received condition of the extractor. It had zero contact with the case, anywhere. The extractor fitting pad was not in contact with the extractor tunnel either. I did rack and few rounds in and out of the gun before doing anything and the rounds dribbled (at best) out of the ejection port. The extractor had no control and I didn't think it was necessary to drive 40 min each way to the range to confirm the issue with live fire. I did not modify the land thickness of the hook from the picture above of the extractor uninstalled, only changed the nose angle to clear the bevel in the case recess. I would venture to say the total contact surface area is similar to an extractor set up to contact the case rim. I did not measure the hook to breach face dimension, but deflection is at .007" as measured with calipers and tension is set at a few good shakes. I've read several arguments against the case rim contact method, one of the biggest being the lack of available rim grab on a 9mm case for extraction. Followed by geometry issues caused by making up for a case rim that is .090"-ish smaller in diameter than .45 ACP. On the other hand, it seems like the case rim method would offer better feeding with more front to back area for rounds to hit as they cam out of the magazine. Thanks for pointing that out. If the gun runs without issues related to the trigger, I'll probably just buy a medium shoe and call it good. I reshaped the left side safety. It is better than before, but I think it will take reducing it to a thumb shield with a nub before it's actually comfortable on my first knuckle. I've always shot striker fired guns or a Shadow 2 in competition and haven't had to clear/ride a thumb safety before. It's going to take some adjustment. I started setting up a new rig for open last night. The LSI grip fits the Safariland 015 no problem. I did a few draws and as suspected, the damn thing is like a cheese grater! I don't exactly have office hands and that grip is punishing, haha.
  4. Thanks. I was able to set the extractor tension and profile the nose to allow for clearance while in contact with the case recess. I'm going to see how it runs and will consider purchasing a spare extractor to set up to contact the case rim. Next up: Pre/over travel in the trigger Pin the ejector Reduce the size of the left side thumb safety.
  5. Thank you everyone for your responses and suggestions, it's very helpful. I finished breaking the gun down this afternoon and started picking away at some of the issues. The hammer strut/grip safety and ejector/magazine interference went pretty quick and is resolved. I slowly started adding tension to the extractor, but had to quit before I got enough to hold a case to the breach face. It's pretty clear the hook is going to make contact with the case bevel first once there is more tension. Once the nose shape/hook to notch relationship is sorted out and contacting the case rim, does the locating pad ever need to be reduced to achieve proper tension? Here is a picture of the extractor removed from the slide. and here is the contact inside the grip safety Looks like there may actually be a pre-travel tab on the trigger, but it's only on the right side.
  6. Hey Folks- I'm looking for some help and suggestions regarding issues with a brand new 9mm major open gun I had built. I'd like to preface this post by saying: I have zero 2011 experience and limited 1911 experience, just with my old beater RIA 45. I have attempted to contact the builder, I'll spare the details in this post. I have not attempted to shoot the gun, however the builder said he test fired it before shipping. During initial inspection and cleaning of the pistol, I went to perform an extractor tension shake test and I think the picture pretty well sums it up. It's a Brazos Pro series performance tuned extractor in a Brazos slide with a Brazos slightly oversize FPS (assuming the parts I supplied were installed) I removed the extractor for inspection and it took a little work with a stiff plastic pick to get it around the breach face. It appears to have some bend in it, the FPS fits tightly in the extractor groove and the extractor is fit nicely to the back of the slide. There is an awful lot of space between the hook and the case, it doesn't seem like adding tension would fix the problem...thoughts? Other questions/concerns- Trigger has a bunch of over travel, reset is pretty soft and almost twice the length of my old RIA. I see there is an over travel adjustment screw but didn't mess with it yet, no pre travel tabs on the trigger bow. Trigger also has a fair amount of up and down movement in the grip. Not sure what kind of trigger ended up in there, I had requested an X-line with the EGW ignition kit I supplied. Grip is an LSI Outlaw. What is an acceptable amount of trigger slop? Movement can be felt in the beavertail when the hammer drops. Seems weird, is this normal? Ding on the disconnector rail, large enough to catch a fingernail. I was able to stone away the raised material. Visible in the picture. Ejector was not pinned. Noticed a gap, tapped it back down and the gap appeared again after seating a few magazines. Pried it out to inspect and it appears to have been installed with loctite of some sort. Is this a normal practice? Last night I handled 2 guns built by a respected local guy and everything about them felt much better. Both were well used, but there was an over smoothness not present in this pistol. Hopefully things smooth out with some use, but it left me feeling pretty apprehensive about the purchase. Sorry about the long post. I'd appreciate any input. Thanks
  7. You'll need 2 spacers, one for each side of the firing pin tunnel. I made some out of .077" aluminum sheet.
  8. Not a great picture but for anyone interested in a window size comparison Left to right- Holosun 407K Holosun 407C Swamp Fox Justice Vortex Venom Bushnell First Strike 2.0 (basically too dim to use, the new version is supposed to be improved, hopefully Bushnell will correct or exchange) I haven't shot with the Justice yet but it's looks pretty good- very bright, clear glass, no extra glue on the lens, good battery cover, positive medium size brightness adjustment buttons. Have not tested the windage or elevation adjustments for feel but don't really care as long as they hold zero.
  9. I have the Pro in both of mine, it's great. I had issues with the Fat Daddy locking out if my trigger pull wasn't perfect. It's easy to make contact with the corner of the extra wide flat face prior to the safety dingus when going (trying) fast. Add a Glock striker spring, Glock/Cajun/Sprinco safety plunger spring, Glock guide rod/recoil spring, Sprinco trigger return spring (or SS split ring) and the TF brass parts to further improve the shooting experience.
  10. Are you using the MBF powder funnel in your powder drop? I think the shape of MBF powder funnel has something to do with it. The depth it must go into the case to achieve enough flare for the bullet to be stable during indexing when fed from a bullet feeding die is greater than what is needed when hand placing bullets before seating. The funnel creates a slightly expanded area below where the bottom of a 115 gr bullet will seat when loaded out to 1.160"+ using the 'bullet feeder" setting, resulting in set back. I lost motivation when my open gun got delayed, again, but I'm going to test this theory a little more as it could be total crap, ha ha.
  11. https://www.thefirearmblog.com/blog/2020/09/17/trijicon-lawsuit-holosun/ Not sure if there is any truth to it, but I read somewhere the X2 series of Holosun optics is the result of the lawsuit with Trijicon. The big buttons on the V2 were too similar to the Trijicon design and have been removed. I have a 407k with the big buttons and it's pretty nice.
  12. Check out Steel City Arsenal, they had the Justice on BF/CM for just under $190. This time last year you could get a Holosun 407C for nearly the same price (or 407A from PSA for even less) but I think the lawsuit and Covid put the brakes on production.
  13. Thank you for the input. I had considered the FCD causing a loss of tension based on what other have reported. Last night I adjusted the sizing die to lightly contact the shell plate and loaded a few more dummy rounds. The only round I loaded that did not set back had so little case flare that the bullet was not stable during indexing. The seating die is backed out of the press (to avoid scraping coated bullets while seating minor loads) but still provided enough straightening of the case mouth that the round passed the hundo gage without going through the FCD. After giving it a few hard leans and measuring it for length (no change) I ran it through the FCD and leaned on it again without set back. The cases that received more flare allowed for set back. I'll experiment with it a little more but seems like the crimp die really isn't doing much at its current setting. Not very confident I'll be able to use the bullet feeder and/or the shape of the power funnel lends itself well to a 115gr loaded to major lengths.
  14. Did you give up on open/major loads? I started down this road last night with similar results.. Set up as follows: Hornady LNL AP Lee U die set a fuzz off the shell plate Hornady powder drop with MBF funnel MBF die with MAG-P Lee seating die Lee FCD Mixed head stamp brass Everglades 115gr V2JHP 1.165" .377" "crimp" I belled the case just enough to hold a bullet without tipping over during indexing then seated and removed the bell like normal. With a good hard lean on the bench I was getting set back numbers ranging between .015"-.045". The round is not deforming, just going deeper in the case. I'm going to try 124s next to see if more bullet in the case helps, but don't intend to give up on 115s yet.
  15. How is the brightness? I've been trying to find a size comparison to other optics in the same price range.
