Looks for Range (1/11)

  1. Finally an update! All of my mags work great after I tuned them using calipers and channel locks. I measured the width of the feed lips in three places, the front, middle, and back. Below are pics. First, mag placed in channel locks and bend slightly, then measure: The front section measures about .457 The middle section measures about .41 The back section measures about .39 The four mags I did are all within a few thousandths in these measurements and run smooth. It seems like the front and middle measurements are most important, I had one mag where the middle and back were fine, but the front was too narrow by one hundredth and it did not cycle well. I'm using factory FMJ and HP ammo, all works well. I did not do anything else, no polishing the insides or anything like that. Before these modifications almost every round would nosedive into the feed ramp and stick, now they don't. I hope this helps anyone else looking for help on this.
  2. Thanks for the advice. I ruled out the extractor being a problem, definitely not that. I'm certain it's the mags, hopefully I'll have time to mess with them soon.
  3. So I popped in a 140mm STI spring, STI follower and stock flat base pad and got some improvement. If I slowly operate the slide the round will slow down on the feed ramp, but if I apply some gentle pressure it will go up and into the chamber. If I rack the slide like normal then it chambers normally. I'll have to try it at the range to be sure. And interestingly enough, the last round feeds flawlessly. That has me baffled, but I think the nose is slightly higher on the last round. I want it to chamber a round when moving the slide as slow as possible, like the rest of my highly reliable pistols. edit: I just did a little comparison between the mag that feeds great with the STI internals and only one round, compared to the mags with Grams springs/followers. There's a clear difference in how the round is positioned relative to the feed lips. Since this is consistent between all mags with Grams internals, I'm thinking it's more of a follower issue. I'll have to do more investigating.
  4. Thanks, I may have to try that. There is some variation in how my mags feed (I have 4) but none is perfect.
  5. Ya, I'll probably try modding a spring to bend a follower up a bit, later this evening and will report back.
  6. I have a new Edge in .40, 126mm mags with Grams Spring/Follower Kit 11 Coil and Arrendondo +1 international pads, everything is new. The problem: Won't feed Federal 155gr JHP, which I have a lot of. It does feed if I rack the slide manually, but I need to do this every round. It also FTFs 180gr FMJ about 40% of the time. What happens is that the nose of the cartridge gets hung up on the bottom of the feed ramp. What I've tried: I lightly polished the feed ramp with 600 grit sandpaper (pushing with an eraser), it feels and looks smoother but not much else, I didn't go too long so maybe I should try a bit more? I don't want to mess up the ramp's geometry though. Should I try bending the follower up a bit? I've read about this too. I know this gun prefers ammo loaded long, but I can't reload right now and it's tough to find long loaded ammo. I'd like to get this running 100% on factory ammo. Thanks for any suggestions, I've been all over the forums and feel like I've read everything. I guess the bottom line is, should I try bending a spring/follower up? Should I polish the ramp more? I guess I'm more comfortable with bending a spring than damaging a feedramp. Thanks
  7. People are even making receivers with 3D printers these days, it's perfectly legal.
  8. Wow amazing! It would be so much fun to be able to do this kind of work for a hobby
  9. Yes, that helps confirm what I've read, thanks.
  10. Hi, I've been doing some reading on which mag base pads will fit my stock STI Edge when using 126mm mags. I just wanted to make sure I understand things correctly: A Dawson +1 won't fit because it's too wide and will hit the mag well? But, something like the Arredondo international pad will fit because it's much narrower and angled? I think this is right but I just wanted to make sure because I don't have any place to buy these locally and would hate to have to pay shipping on a return. Also, do you guys have any favorite base pads for 126mm mags? I really want to upgrade the stock pads to something very durable and reliable. Thanks
