B_RAD Posted November 15, 2016 Share Posted November 15, 2016 Last night I was doing some dry firing and I had the mag in the gun so I could work on dropping it when reloading. I started having a new, weird issue. The trigger/sear/hammer would stop engaging on the DA pull. It felt like the hammer hooks and sear weren't engaging enough. When I'd take the mag out it'd work everytime. Put it back in and it work on the first pull or two then it do it again. The trigger was going forward enough to reset. I though the trigger return spring had broken it it looked fine when I took the slide off. I've never noticed this before. Anyone else seen this?

B_RAD Posted November 15, 2016 Author Share Posted November 15, 2016 My guess would be the mag is pushing up on the slide and that's taking weight off the trigger bar, which is being pushed up by the lifter spring and is being lifted too high. That's causing the trigger bar to not engage the hammer properly. I tried it with an empty mag and a loaded mag (dummy rounds). Same thing. I guess as as long as it still functions properly when firing there's not issue. Just can't dry fire and have a reliable DA pull with a mag inserted. Though, it's weird that it just started.

repins1911 Posted November 15, 2016 Share Posted November 15, 2016 Have you tried different magazines? Not trying to be that guy, just asking. Is there any evidence of pressure on the trigger bar from the mag? Link to comment Share on other sites More sharing options...
TennJeep1618 Posted November 15, 2016 Share Posted November 15, 2016 I had the same issue at one point: In my case, the magazine was contacting the trigger bar spring. Make sure the screw is tight and that the spring is bent in such a way that the magazine doesn't contact it. Link to comment Share on other sites More sharing options...

B_RAD Posted November 15, 2016 Author Share Posted November 15, 2016 (edited) If it wasn't for how accurate these are, I'd switch back to plastic! I feel like these are worse than 1911's when it comes to getting them working and keeping them running! I did a little shooting this last weeked. Here's 40 yds off hand 10 shot group 3.5" Edited November 15, 2016 by B_RAD Link to comment Share on other sites More sharing options...

Here's a list of what I've done so far, still want to do and spare parts. Parts replaced (no big deal. A lot of guns need tweaks initially and these weren't expensive) Hammer spring Trigger return spring Safety detent spring Trigger pin Firing pin and spring Disconnector Parts know to be replaced often (A lot of guns need spare parts but from what I've heard these break often) Trigger return spring Slide stop Work I've done to mine Polish internals Bend magazine release spring Work I want to do Ream chamber File slide stop for longer OAL (if needed) Mags are $60 bucks ea! Then I'm seeing guys having a practice gun and a match gun?! Though, I guess you'd probably want a spare for any gun if you're gonna seriously run it in competition. And today I'm discovering another issue with the screw for the trigger lifter spring! I'd say they're at least as bad! Saying all that, I'll admit, they're easy to work on. Not as easy as a Glock but easy. Edited November 15, 2016 by B_RAD Link to comment Share on other sites More sharing options...
MemphisMechanic Posted November 15, 2016 Share Posted November 15, 2016 Damn! For reference from Tanfo-land: stock II or III: $900 DP sight: $40 Springs, disconnector, hammer, etc etc: $380 Grips: $50ish ... at least I found factory mags from CDNN for $15 each. I shot an M&P for seven years. Aside from a $200 Apex fitted-barrel I only fed it (3) recoil springs and ammo for 35-40,000 rounds. Link to comment Share on other sites More sharing options...
thompsoncustom Posted November 16, 2016 Share Posted November 16, 2016 Some of the mec gar AFC mags can causing the trigger bar to drag on the side of the mag and cause issues like that. Link to comment Share on other sites More sharing options...
B_RAD Posted November 16, 2016 Author Share Posted November 16, 2016 I took a look at the screw. It wasn't what I would call loose. I was able to torque it down a little. Shoot about 100 rnds at indoor match. No more problems. Link to comment Share on other sites More sharing options...

That's what I was using when it happened. Im switching to the nickel plated ones with 10% springs and SP base plates.

thompsoncustom Posted November 17, 2016 Share Posted November 17, 2016 (edited) Ya i dont use any of the AFC mags for that reason tho im sure you could polish the inside of the trigger bar and/or the mag where it touchs. Hopefully the screw takes care of your issue tho and you dont have to worry about it. Edited November 17, 2016 by thompsoncustom Link to comment Share on other sites More sharing options...
B_RAD Posted November 17, 2016 Author Share Posted November 17, 2016 What's different about the AFC vs the nickel plated? Are they wider? What is it that causes the problem? Link to comment Share on other sites More sharing options...
teros135 Posted November 17, 2016 Share Posted November 17, 2016 Never had a problem with MecGar 9mm 17rd AGC mags in my CZS (33k rounds total). Does anybody else have this problem? Link to comment Share on other sites More sharing options...
TennJeep1618 Posted November 17, 2016 Share Posted November 17, 2016 I gave up on the MecGar AFC mags because 5 of my 8 wouldn't fall free. I switched to factory CZ SP-01 mags with +10% springs and they haven't missed a beat.Sent from my SM-G920V using Tapatalk Link to comment Share on other sites More sharing options...
