View Full Version : How to check if pistol will fire out of battery?

If the striking pin does strike with a round not in optimum seated position in chamber (the slide will definitely be jammed, but in stress situations, it may not be noticable), there is every possibility of a 'kaboom', and can cause serious damage...


I was thinking if there are any safe ways to check whether a semi-auto pistol will fire (or the firing pin will strike the bullet) when the gun is not in battery i.e slide is not fully forward (due to a stuck bullet, ftf), and slide has another 3-4mm to go till it reaches the default 'ready to fire' position.

Expert opinions?

Try getting a few primed cases(no powder or bullets) and test it. If the gun sets off the primer it could fire out of battery.

I'm thinking that we could put the rubber end of a pencil down the barrel of handgun (after making sure that its empty of bullets) till the time it rests against the firing block. cock the hammer and press the trigger. the pencil should shoot out 6 inches or so. if that happens, the firing pin is striking the rubber base of the pencil. now if we tilt the barrel straight up (muzzle pointing towards the sky), cock the hammer and press the trigger, the pencil should atleast bounce 3-4 inches inside the barrel instead of shooting out, also indicating a successful primer strike.

second phase: we pull the slide back just 2-5 mm and do the same procedure again with a pencil resting against the firing block, if it bounces again, the firing pin is again striking the pencil. indicating a potential catastrophic failure. however since most modern handguns come with a myriad of safeties these days, the chances of pencil bouncing is quiet slim when the slide is retracted just a weee bit (2-5mm).

Excellent input 12guage. Very practical test. Tried it on 4 handguns. In PT99, Viking and Makarov, the trigger can not be pressed if the slide is moved even very slightly (like 1-2 mm). In CZ999, the trigger can pressed but the firing pin does not strike the pencil means firing pin safety of CZ999 is working well :)

thanks for the input, 12guage :)
