9mm Shield double discharge

[drillerdude]

Today while firing a 9mm Shield at the indoor range I experienced two incidences where the gun discharged a second time immediately after a single trigger pull. I have fired over a thousand rounds through a Shield and have never had this happen before. The ammo was factory Winchester 115 gr FMJ. The first time it happened was after firing about 75 rounds through the gun on this trip to the range and I assumed it was somehow related to some way I had manipulated the trigger. After a few more rounds it happened a second time and this time I'm pretty confident I did not cause it. In fact I couldn't fire that fast if I tried. Until I sort this out the gun is back in the closet. Any suggestions?

Immediately call customer service and get that gun back to Smith. Not only is it potentially dangerous, there is a potential legal liability in a gun that will fire more than once per trigger pull.

Listen to epj, send that thing back and let them figure out what is causing the problem and see if they need to do a recall to fix others that may have the same problem.

I would bet there is just some fouling in the trigger group area. I would field strip the gun (or go further if you have the skill) and flush out the internals with the solvent of your choice, followed by some compressed air. You can use brake cleaner if compressed air is not available. Lube and re-assemble.

BTW, there is nothing illegal in having a gun malfunction, and this is not that rare of a malfunction.

I very vividly recall the ATF prosecuting a guy with a 1911 that went full auto at a public range. I think the charges were eventually dropped, but not without a great deal of legal hassle.

You have told the world that some really bad malfunction is occurring, one that might endanger people. Best to have the factory fix it to prevent any future accident that you might have to answer for. 'Fix' it yourself and then it happens again and you might have to explain to a criminal or civil court what your qualifications are to fix such a malfunction.

I have heard others make similar claims, but have never been shown any data or other evidence to back up the assertion.

Quick double taps.

 

[hoc9sw]

I would call and see about sending it in.

I would follow the advice above about giving the trigger internals a good cleaning and give it another try before sending it in. The only way I see a legal issue is if the gun had been tampered with or modified in an attempt to make it fire "full auto".

Thanks guys. Gun has been shipped to S&W. I'll post their findings when gun returns.

You did the proper thing.

Definitely keep us posted. Thanks.

I bought a Shield about a month ago and this has happened to me a couple times in about 300 rounds. I thought I did as I'm new to pistol shooting but I will monitor. As long as it's pointing down range it doesn't bother me too much.

 

[epj]

Do you know where the second round went? What would have happened if the disconnect completely failed and you dumped the mag? Personally, I would not fire that gun again until the cause of the malfunction had been positively determined and repaired.

 

[Warren Sear]

Even if the disconnector were completely removed from the gun, it will only fire once, and then a stoppage will occur. Try it, and you will see. The disconnector is not there to prevent automatic fire.

I'm gonna guess something about the word "knowingly" caused a hitch in the prosecution's getalong . . .

My guess about the malfunction is that the firing pin is sticking out of the breech face occasionally, not retracting after firing . . .

Exactly the same thing I was about to type.

You might want to pull that firing pin and give the whole channel a real good cleaning. Chances are somewhere along the line you fired some dirtier than normal ammo and some of the residue built up in there or dirt flew in off a dropped mag. They always made us drop ours in the dirt when qualifying many times.
That said, I just pulled the one on my Glock out for the first time after 18 years of quarterly qualifications. Pretty clean actually to the point I was surprised. Still, you never know what can end up in something after a while. It's worth a look and the first place I would look for that issue.

Did you try that ammunition in another pistol?

Did anyone else try that pistol?
