Bapple Posted July 12, 2017 Share Posted July 12, 2017 Took my EAA Witness P to range today for first time. Felt great in hand. VERY accurate, my first 10 rounds were at 5 yds and all 10 were in a quarter size hole. Was having one major problem though. The slide kept locking back with rounds still in the magazine. This was just a few times either, I shot 100 rds through the gun and there could have been as many as 25-30 times where the slide would lock back with rounds still in the magazine. My first thought was, I must be riding the slide release. So I intentionally tried to keep my support hand away from the release. Did not seem to work. So then I thought, hell, lets shoot the gun one handed, then I know I am not riding the release because that hand isnt even touching the gun. Still continued to lock back with rounds in the magazine. I could not pinpoint when nor why it was doing this. Any help or suggestions or thoughts on what might be going on? Link to comment Share on other sites More sharing options...
kneelingatlas Posted July 12, 2017 Share Posted July 12, 2017 It's the bullet profile, where are you getting your ammo? If you want to eliminate the problem without changing ammo, file the nub on the slide stop. Link to comment Share on other sites More sharing options...
Bapple Posted July 12, 2017 Author Share Posted July 12, 2017 I was just using Blazer Brass 124gr. Should factory ammo cause the slide to do that? Link to comment Share on other sites More sharing options...
kneelingatlas Posted July 12, 2017 Share Posted July 12, 2017 Do you access to a set of calipers? The most common bullet weight for factory 9mm is 115, 124s tend to have a slightly longer ogive, and if the OAL we're on the long side for factory ammo, the bullets might contact that nub enough to lock the slide prematurely. We're talking about a $300, mass produced gun, the chances of it working perfectly with every variable in the ammo market is slim, if they made the nub thinner, not every mag follower would catch it and lock the slide back. This is just my theory sight unseen, it's possible there's another cause, if you really want to know try some 115gr factory ammo. Link to comment Share on other sites More sharing options...
Bapple Posted July 12, 2017 Author Share Posted July 12, 2017 Thanks for the help. Will test out some factory 115gr FMJ's and see how it goes. Will keep you informed, thanks again! Link to comment Share on other sites More sharing options...

Bapple Posted July 15, 2017 Author Share Posted July 15, 2017 Went back to the range today and put 150 rounds of 115gr. Blazer FMJ downrange. Switching to 115gr did not seem to help. The slide continues to lock back sporadically with rounds still in the magazine. Any other thoughts on why this would be happening? Thanks Link to comment Share on other sites More sharing options...
johnbu Posted July 16, 2017 Share Posted July 16, 2017 Did you shoot left hand only? Link to comment Share on other sites More sharing options...
Bapple Posted July 16, 2017 Author Share Posted July 16, 2017 I did shoot right hand only. So the left hand was completely out of the equation to touch the slide release while firing. Still happened. After coming home to take a look, I took the slide off and then inserted a magazine back in the frame with the slide release installed also. I dont see how the rounds could be hitting the slide release, there is more than enough room between the rounds and the slide release on the inside of the gun. What I did observe is the trigger bar looks very close to the bottom of the slide release.Do you think there is anyway the top of the trigger bar could be contacting the slide release and pushing it up?

johnbu Posted July 16, 2017 Share Posted July 16, 2017 Your right THUMB is what i question. Shoot left hand only. Link to comment Share on other sites More sharing options...
Bapple Posted July 16, 2017 Author Share Posted July 16, 2017 My right thumb barely reaches the safety, much less anywhere close to the slide release. So I don't think I am inadvertantly hitting the slide release. Some other gremlin is showing up somehow/somewhere Link to comment Share on other sites More sharing options...
kneelingatlas Posted July 16, 2017 Share Posted July 16, 2017 Do you have any other slide stops you could try? Link to comment Share on other sites More sharing options...
Bapple Posted July 16, 2017 Author Share Posted July 16, 2017 The only spare I have is for my Tanfo Stock 2. They are shorter than the one in the Witness P so it will not work. Link to comment Share on other sites More sharing options...
johnbu Posted July 17, 2017 Share Posted July 17, 2017 Sadly, I'd need it in my grubby mitts to learn more. I'd still try left hand only. But assuming you're correct, close inspection on your part is needed. Link to comment Share on other sites More sharing options...
7mmb Posted July 18, 2017 Share Posted July 18, 2017 The same thing used to happen to me with my 45 P Carry when it was new. I couldn't figure the thing out, not hitting the slide lock and the bullets in the mag weren't hitting it either. After about 500 rounds, not sure exactly but certainly not more than that, it stopped and hasn't happened since. If you figure it out let me know. If it just stops after break in let me know too. Thanks. Link to comment Share on other sites More sharing options...
