My Colt Systema jams via the firing pin

When I dry fire and the firing pin is driven forward until it sticks out of the slide and stays there. Then when you try to chamber a round the firing pin is sticking out enough to make the round not being controlled fed. When it happens I reach in and push on the pin and it snaps back through the firing pin stop. By the way when this occurs the firing pin stop drops down sometimes exacerbating the proble. I've polished the firing pin like a mirror, but the tapered part is what is causing it to stick. I'm thinking the firing pin spring is too weak?

Seems like I put a Wolff package in the gun about 10 years ago. But knowing me I probably said to myself. "They aint nothing wrong with my firing pin spring" and threw it in a box of gun parts. So I'll look around for it.


Thanks

OH, that can be bad, a stiff recoil spring and a weak firing

pin spring set you up for a slam fire should the gun get dropped. Not that YOU would ever drop a gun...but, it has been known to happen.:-);-)

New f/p spring - Wolff extra power if you have one - they come in the Wolff kits. Also, while you have the f/p retainer out, you might take a small prick punch and raise a couple of burrs on the front side of it, on either side of the hole, so's it fits tight (light tap-in fit) and won't drop down.

For that matter, an oversize f/p retainer from Brownell's isn't very expensive and will cure the problem for sure. Helps keep the extractor from clocking as well. Will need fitting to the slide, but that's not difficult. Fixed my old Commander up nicely a few years back.
