New SP01 Shadow Trigger Reset Issues

[j_king]

Just got a new SP01 shadow from CZC about a week ago.  Took it out last night and put about a hundred rounds through it.  I had A LOT of trigger reset issues.  I would say about 95% of the time the trigger would not reset after shooting.  I would then remove the mag, rack the slide to remove the round that was chambered, re-insert the mag, rack the slide and then it would fire. Then the same thing would happen: round fired, new round chambered, hammer cocked, but the trigger would not reset.

I can sit here and dry fire all day long and the trigger resets with no problems.  Any recommendations or thoughts on what might be happening?

FYI: its an SP01 Shadow that CZC worked over with a SAO trigger, competition hammer, lighter firing pin spring and extended firing pin.

I would take several pictures of it so I could look at it while it is at CZC. But that is just me. Even if I could work on it this should be addressed by them just from a liability and warranty standpoint. I would request the gun be live fired with standard factory ammo before it was returned.

SAO trigger?

I would check the pretravel adjustment make sure there is enough room for the trigger to reset?
also check the trigger bar spring ( both sides ) are in the correct position.

Yes it is the SAO.  Will do on checking the pretravel screw, maybe will back it off a bit

The weird thing is that it resets just fine when pulling the trigger/manually racking the slide/let off during dry fire.  It just wouldnt reset when actually firing rounds.  It might have actually reset about 7-10 rounds out of 100 at the range, which would make me thing that the pretravel and overtravel screws are fine since it would work some of the time.

It is set that close..the shock of the slide racking on an empty chamber can be enough to set the sear.
When shooting livefire, there is enough cushioning from stripping a round out of the mag and chambering it that it can hinder the reset.

Thanks for the help Stuart!

I backed off the pre-travel about a quarter turn, took it to the range last night and put about 200 rounds through it with only 1 failure to reset out of those.

I'll probably back it off 1/8th of a turn more to ensure maximum reliability and locktite it there.  Thanks again for the advice, and I'm not sure if you worked on the Shadow that I recently got from you guys, but it is a smooth shooter!

Thanks.

I had the same issue with mine and Stuart helped me through that . Mine would loosen up at about 100 rounds until I took it apart degreased and blue loctite both set screws. So far it has stayed good for approximately 600 rounds.
