Astocks2622 Posted March 13, 2016 Share Posted March 13, 2016 Been shooting my Stock 1 for about a year now, and at first had the occasional premature slide lock, and chalked it up to bumping the slide lock with my left hand. Now it's doing it every 3-4 rounds, and it definitely isn't just me. I don't think that the nose of the top round is pushing up one the slide lock. Only mods are a Henning cone fit guide rod, 20lb spring, and FO front sight. Any ideas? Link to comment Share on other sites More sharing options...
johnbu Posted March 13, 2016 Share Posted March 13, 2016 Did you try shooting it left hand only? Can't bump it at all that way. I only bring it up as that's the most likely cause (historically) and doing that will for sure rule it out. I would take off the slide and see what happens when I pushed down on rounds in the mag and let them pop up. Paying strict attention to the slide lock. Maybe sharpy mark it up where it may be touched inside the gun. Then shoot and see if that sharpy is rubbed off. Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 13, 2016 Author Share Posted March 13, 2016 Yeah, tried that. Seems like it did it slightly less, but still did it repeatedly shooting lefty. Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 13, 2016 Author Share Posted March 13, 2016 Bullets are definitely not touching the slide lock. Is it possible that the recoil is sharp enough to move the slide lock on its own, meaning the retention/actuation spring is weak?

Astocks2622 Posted March 13, 2016 Author Share Posted March 13, 2016 Another, unrelated problem is that the elevation adjustment on the lpa rest sight walks a good bit. The detent seems solid, but clearly isn't doing the job. Can I blue locktite the screw once it's just right?

Intercooler2 Posted March 13, 2016 Share Posted March 13, 2016 It won't hold. The sight is wore out and have you had any issue with the slide stop pushing out? Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 13, 2016 Author Share Posted March 13, 2016 Yes, occasionally the stop will work it's way out. Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
johnbu Posted March 14, 2016 Share Posted March 14, 2016 (edited) It sounds like that spring is weak then. Pretty sure only EAA or maybe Numrich would have it. https://www.gunpartscorp.com/Manufacturers/EuropeanAmericanArmory-33215/AutoPistols-36073/WitnessFullSize-34951.htm?results=50 Part 36.

Intercooler2 Posted March 14, 2016 Share Posted March 14, 2016 You need to pull the stop out and file the groove the spring sits in deeper. In 10mm it has more recoil induced issues and this can be one. Try it again after making the groove deep enough to retain the stop firmly. Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 ok, I did file the slide stop pin detent a bit deeper, and that solved the problem of the slide stop walking out. I verified that the issue is NOT me. I tried going back to a lighter recoil spring, I tried different bullet weights, still getting multiple premature slide locks in a magazine. I'm waiting for the new slide stop spring, but it's gonna have to be significantly stiffer to exert enough force. the entire down-force on the slide stop comes from pushing on a small flat on the detent groove, so there is almost no leverage, or mechanical advantage. is this just an issue with the 10mm witness line, or did I just get the perfect storm?

ATLDave Posted March 16, 2016 Share Posted March 16, 2016 This has not been an issue with any of the 3 10mm Witnesses (2 Matches, one Limited) that I have owned and shot many thousands of rounds through. Link to comment Share on other sites More sharing options...
Intercooler2 Posted March 16, 2016 Share Posted March 16, 2016 Same here and I have three different models of EAA 10's. I'm really thinking you are activating it somehow. You can inspect your followers and see if that shows anything funky. Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 I shot it righty, I shot it lefty, 2 hand, one hand, same results, so it is not me bumping the slide stop. the followers are nowhere near the slide stop when there are rounds in the mags. it's not an issue only on the last round or something, it's throughout, full mag, partial mag, or nearly empty, and the same with all 3 mags. With my grinding on the ejector and slide stop, I can't even send it back to EAA, can I? Link to comment Share on other sites More sharing options...
ATLDave Posted March 16, 2016 Share Posted March 16, 2016 The ejector and slide stop are replaceable parts. Have you tried throwing a new/different slide stop in there? Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 (edited) Not yet, they're $45, and before I just start throwing money at it, I was hoping there was an easy, cheap fix. worse comes to worse, I could just go to the EGW tool steel pin that eliminates the slide-lock function, but I'd rather not. http://www.egwguns.com/index.php?p=product&id=436 Edited March 16, 2016 by Astocks2622 Link to comment Share on other sites More sharing options...
ATLDave Posted March 16, 2016 Share Posted March 16, 2016 OK, just brainstorming. When you get to premature slidelock, can you drop the slide just by pressing on the slide release? Is there any chance that you're actually getting, say, binding of the (thick and heavy 20lb) recoil spring against the frame or slide? Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 Good thought, but no, the slide lock is engaging the slide. I can drop the slide by using the release lever, or by racking it. Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
ATLDave Posted March 16, 2016 Share Posted March 16, 2016 And if you cycle the slide by hand, it never does it? Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 Not that I can remember. I'll try running several mags through by hand. Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
ATLDave Posted March 16, 2016 Share Posted March 16, 2016 When you do so, see if just barely short-cycling it will cause it. By which I mean letting the slide move forward just before it gets to the end of the rearward stroke. Also do it with a complete stroke, too.

Intercooler2 Posted March 16, 2016 Share Posted March 16, 2016 You read about this every so often and tons of these pistols out there. It's something very stupid I bet! Your spring isn't broke or out of whack is it? I would rather take a swift kick to the jewels than send anything back to EAA unless it's last resort!

Astocks2622 Posted March 16, 2016 Author Share Posted March 16, 2016 Don't think so, but l I've got a spring coming, jic. I actually had a good experience with EAA cs. Had a wonder finish Steel in 10mm that crashed the slide (the scalloped ones). EAA replaced the slide with one from a Match, and gave me an ambi safety and extra mag for my trouble... But that was 8 years ago or so. Sent from my MotoG3 using Tapatalk Link to comment Share on other sites More sharing options...
Astocks2622 Posted March 17, 2016 Author Share Posted March 17, 2016 well, I cycled over 100 rounds through the gun by hand with no malfunctions. all 3 mags, fast, slow, short stroke, full cycle. I even assembled the gun without the guide rod or recoil spring so I could really over control it. no issues whatsoever. at least I know it will feed every time no matter how much I ride the slide home. If the slide stop doesn't engage, it's 100% when firing. I have never had any other type of malfunction. Nothing looks out of place in the gun, all springs are present and in one piece. I guess I'll have to wait until the slide stop spring gets here and try it out again. if that doesn't work, I'll try a new slide stop. then it's off to EAA if those don't solve it. This was supposed to be my woods carry & occasional open carry gun, but I can't trust it to get more than 2 shots sequentially... Link to comment Share on other sites More sharing options...
Intercooler2 Posted March 17, 2016 Share Posted March 17, 2016 Their are at least a couple of us here shooting extreme 10mm rounds (I have thousands of rounds) and have never changed a single thing other than recoil springs. Something wacky going on! Link to comment Share on other sites More sharing options...
