Shield .40 Return to battery problem

[lumberjack2003]

You'll probably also note that when you take up the slack in the trigger the slide will return to battery. So if you do get into that unlikely scenario, you're still OK because it WILL still go bang.

haven't tried that yet, dont have any spent casings or snap caps at the moment. I might be able to replicate it with just a loaded magazine in the well. Ill see what happens.

EDIT - did some more testing today.

my gun does stick outside of battery with either a round in the chamber, a loaded mag inserted and an empty chamber (any number in the mag), and both. That being the case, where is it sticking? or is it just not enough recoil spring pressure? I may break out the dremel and polish a few spots untill it goes away. dunno yet.

it also WILL return to full lockup with a trigger pull, so if your in a stick spot, pull the trigger twice, three times, etc.... lol. repeat as necessary.

I just tried this with my Shield 9 using snap caps. When out of battery, it does return to battery by lightly touching the trigger. The gun stopped displaying the OOB with my 8 round mag. It seems even OOB will not prevent this firearm to fire after all.

I think we can put this issue to rest. My Shield 40 also pops into full battery when I partially pull the trigger. The trigger bar tab (for the striker blocker and reset) is what is holding the gun out of battery. The tab is being held over for the trigger reset by the hump in the slide. When the trigger is pulled, the tab moves past the hump and releases the pressure on the slide, which is then moved into full battery by the pressure of the recoil spring.

All that have found this problem now know it is a non issue. The slide snaps back into full battery when the trigger gets partially pulled.

Kind of the Same Issue

Wow, this really helped me. I just picked up my Shield in the .40 and at 62 rounds in all was smooth then mid magazine...FTL...I cleared the bullet but even after I got done clearing the gun it would not go back to battery. I had to finagle it for about 30 minutes(since it was stuck, could not disassemble because it was stuck) I some how pushed something underneath the slide and it clicked and went into battery but even after that it still hasn't loaded like it did earlier in the day.

I have emailed S&W about it but of course it is late Friday night and won't hear anything till Monday.

Did you ever have that issue? This was not that I didn't rack it properly because it was mid fire when it happened then just locked back(not full lock like empty only about 1/4") You'll have to let me know what you did.

Thanks!

What I saw on some other peoples posts on another forum, and on a video posted here; is that IF the slide gets nudged back from full lockup, it will not return to fully closed. and once that happens, it will not fire.

see this thread: Concealed Carry Forum - M&P Shield - out of battery failure

and video: M&P Shield 9mm Problem - YouTube

I really think in this video he is exerting far more force than a bump from a holster would. He is bracing the grip with with one hand and pushing back on slide with other.
Do this same test as you would with a one handed cycle drill against the edge of a table or boot but instead of trying to cycle just bump it on sights or edge of the slide, but be careful as not to bump end of barrel as it will counteract rearward forces. I've done so and it will not bump out of battery unless you hold pressure as if you were fully cycling the gun.

"Return to battery problem"? I always refer to that as FAILURE to return to battery. That is not acceptable, to me. It is, by definition, a failure of the firearm.

As to "pulling the trigger a little bit to get it to go back in battery".........really?

Anyone else see the potential for ND's with that plan?
