just press on the firing pin at the hammer end of the slide and see if the pin extends beyond the frame where it impacts the primer of a cartridge, it should move freely and easily.....if it does you should be fine  :)  If the firing pin doesn't move freely/easily, its binding somewhere and you will have to determine where its binding at......

Make sure it's empty, point the muzzle up, insert a pencil into the muzzle and let it drop to the breechface.  Cock the hammer and pull the trigger.  If the pencil jumps upwards (usually they'll exit the muzzle) it'll set a cartridge/primer off.

Then pencil test, it's called.
Better to have it and not need it, than to need it and not have it.  So, if you see me walking the dogs with my SIG 556R, its okay.

Just make sure the pencil tip doesn't set inside the firing pin hole, make sure the tip is blunt/large enough to rest outside the hole, like a primer would be, to ensure the FP tip is extending beyond the hole when the hammer falls and pushes the FP to the pencil tip....better yet an if you choose this method use and unsharpened pencil ;D

Thanks for that test. Put back end of pencil in, pulled trigger and bam, pencil shot out of barrel. Again thanks to both M1A4ME & Guardian for your help.
