echotango Posted January 11, 2023 Share Posted January 11, 2023 (edited) I have a buddy with a legion and had a trigger issue tonight. The trigger only resets if you rack it. If you fire it, dead trigger. Rack it, it works. Any ideas? He is not local to me so I can't take it apart. Thanks Edited January 11, 2023 by echotango Link to comment Share on other sites More sharing options...

What recoil spring is he using? It seems like the slide is not moving far enough backwards to reset the FCU. Another thing to possibly inspect is the ejector. If he has done dry fire and over inserted the mag he could have bent the ejector upwards that would create drag on the slide possibly preventing the slide from operating correctly during normal operation. Hand racking may over come that drag which allows the trigger to reset. Edited January 11, 2023 by Boomstick303 Link to comment Share on other sites More sharing options...
echotango Posted January 11, 2023 Author Share Posted January 11, 2023 Factory 12#. The slide goes back during recoil and he barely has to rack it to reset. Much shorter than the recoil distance of the slide. I will have him check though. Link to comment Share on other sites More sharing options...
Boomstick303 Posted January 11, 2023 Share Posted January 11, 2023 Other info would be help as well. Has he done a trigger, if so which one. Has he mixed matched parts by chance, or is it a stock gun? Link to comment Share on other sites More sharing options...
Boomstick303 Posted January 11, 2023 Share Posted January 11, 2023 Another thing to think about is a buddy was riding his support hand thumb on the slide which was creating malfunctions. He may want to video shooting the gun to see if he is doing that. Link to comment Share on other sites More sharing options...
Joe4d Posted January 11, 2023 Share Posted January 11, 2023 maybe its not the racking, its the next bullet not quite going all the way into battery Link to comment Share on other sites More sharing options...

If the gun was dry and dirty maybe the 12# spring is too weak. I will not run springs under 14#s in my P320s. Link to comment Share on other sites More sharing options...
echotango Posted January 11, 2023 Author Share Posted January 11, 2023 Thanks all. I will let him know all of this. It is tough not being able to see it in person. Link to comment Share on other sites More sharing options...
ddc Posted January 11, 2023 Share Posted January 11, 2023 Have him check his grip weight. Make sure it is all the way seated. If it drifts up more than a little bit it can interfere with the functioning of the trigger bar and spring enough to cause this effect in an otherwise reliable gun.

tt350z Posted January 11, 2023 Share Posted January 11, 2023 Does he have a trigger job? Is it an actual dead trigger as in it’s binding, completely frozen, pinned at the back, pinned at the front? Does the trigger have full travel but striker wont release? Is the striker/sear engagement minimal enough that it will engage when slowly hand racking the slide but slips during live fire when slide velocity is much faster? Remember, due to the loose slide to FCU rail fit, a fully loaded mag pushes the slide up which decreases striker/sear engagement. Is the striker reset spring broken? It’s a tiny tiny spring. If it’s broken the striker wont reset. Sig claims this was the cause of one of the recent P320 discharging by itself as well. Link to comment Share on other sites More sharing options...
echotango Posted January 11, 2023 Author Share Posted January 11, 2023 He has a GG trigger kit. He is going to clean it, disassemble/inspect the striker, check the ejector and check the set screw on the trigger. He has to take it to the range to test, so will have to wait to see what happens. Thanks all. Link to comment Share on other sites More sharing options...

Thanks Sounds like he may have re-assembled it before installing the take down lever, assembled without the take down lever in the fully down/7:00 position, or try lifting the slide catch lever to reset......... https://youtu.be/lfFpQ_0GQpY https://www.youtube.com/watch?v=j6Gu2-P6nWI Edited January 11, 2023 by HOGRIDER update Link to comment Share on other sites More sharing options...

He was shooting a match and half way thru a stage it started happening. On the next stage it would only fire if he racked it. Link to comment Share on other sites More sharing options...

I would back that screw out completely and see if the gun exhibits the same issue. Link to comment Share on other sites More sharing options...

jaep1911 Posted January 12, 2023 Share Posted January 12, 2023 My GG trigger doesn’t have any adjustment for pre travel, I believe in order not to compromise the striker safety. Link to comment Share on other sites More sharing options...

There can still be a problem with an over travel screw. If the screw somehow gets screwed in too far then the trigger/trigger bar will not be able to move the sear enough for the sear to trip.

fireman1776 Posted January 12, 2023 Share Posted January 12, 2023 The description of the problem is vague but this same thing happened to me during a match. It was the trigger return spring. I put a new one in it and the problem was fixed. I was using a grey guns kit and they told me it needed to be replaced every 2,500 rounds. I had 5,000+ live through it and can't even count how many dry reps. Link to comment Share on other sites More sharing options...

Sorry not Pre Travel, that should have read Over Travel. Link to comment Share on other sites More sharing options...
echotango Posted January 12, 2023 Author Share Posted January 12, 2023 (edited) Problem solved. The over travel screw moved. It has blue loctite but moved just enough to have an intermittent issue. Re-loctite, adjustment and done. Edited January 12, 2023 by echotango Link to comment Share on other sites More sharing options...
