Firing Out of Battery

Well, it took me a while, but I finally did join 'that other site'. I don't post but I do sort of lurk around and read.
I don't know if any of ya'll are members over there or not, but there is a member there who posted a thread about a 5.7 that blew up in his hand because it fired out of battery! I pulled the magazine from mine and inserted an empty and tested my own personal weapon. It fired a full 1/4 inch out of battery!
I'm sorry ya'll but that scares me. I'm using this as a duty weapon and now I find this out? I never would have thought it unless I tested it.
He went on about how FN never really got back to him and he feels like they just wished he would go away, or else they just forgot about him. I can't imagine I would forget a customer whose gun blew up in their hand!
He did say that he was shooting reloads, and normally I would have jumped all over that as I know a lot of reloaders who tend to 'hotload'. But firing out of battery has nothing to do with the load charge. That's purely mechanical, and in this case, poor design.
Just kowing that mine COULD fire a full 1/4 inch out of battery has me to the point that I'm switching holsters today and putting my Glock back into service.
I can't believe that I bought a $900 'target pistol'. :cry:

I tried the out of battery test on mine and the hammer will drop when the slide is back slightly (read: up to 1/4"), however, IT WILL NOT FIRE OUT OF BATTERY. When the hammer drops before the slide is completely in battery the hammer contacts the rail used to cock the hammer and not the firing pin itself. The hammer can only contact the firing pin when the slide is in FULL BATTERY. The hammer can ride the rail until it is in full battery and only then will the hammer fully strike the firing pin & primer. Just checking to see if the hammer will drop while out of battery is only half the picture which the other posters on that "other" sight conveniently ignore. I love how that poster of the Ka-Boom says he is sure his RELOADS did not cause the problem. Had this happened with factory ammo I might rethink the situation.

I feel perfectly confident using my 5.7 for CCW,

If a dimple on an unfired primer is your criteria then I would have to stop shooting all of my AR's, my XCR & all my 1911's. When a round is chambered in all of my rifles the firing pin makes light contact and will leave a very noticable dimple in the unfired primer. In fact you find dimples in unfired 45ACP rounds in my Kimbers and Springfields. The slide in the pistols and the bolts in the rifles slam forward with enough force to overcome the firing pin spring slightly causing the firing pins to contact the primers but not with enough force to fire the round.

A dimpled primer on an unfired round IS NOT a good test for the prevention of an OOB firing.

MadDog :-?

ETA: The more I think about it, the more I am convinced it was a bad reload. A double charge in a 5.7 casing could definitely cause the damage as described.

Please post the results of your personal tests with the dummy rounds you are having made for you. I am interested to know what happens.
