[ARCHIVED THREAD] - problem

I went shooting this morning and had a problem with my Springfield 1911a1.
The firing pin stop fell out part way and jammed up the gun, I put it back but this has never happened before.
I got the gun used from a friend he didn't shoot it much maybe a few hundred rounds and I only shot it maybe 150 rds.
I'm wondering if the firing pin spring is weak and it didn't hold the firing pin back with enough pressure.
Any other thoughts.

thanks

SA uses a titanium firing pin and subsequently a lighter firing pin spring. I'd replace the titanium firing pin with a steel firing pin (http://www.brownells.com/.aspx/pid=1323/Product/1911-AUTO-FIRING-PIN)

Stock #:087-205-826WB

And I'd replace the firing pin and recoil springs (they should be changed in tandem), my preference is a 18.5 recoil spring and an extra power firing pin spring.

check that the firing pin spring is installed on the correct end... one loop is tighter, and that fits tight to the firing pin... if the spring is reversed, the tighter coil can trap the firing pin and hold it, allowing the firing pin stop to move

You can also have an oversize firing pin stop fitted to the gun. Kitchen table gunsmithing solution would be to prick the edges of the inside of the stop with a small punch - you just want to displace enough metal in a few spots to make it fit tighter.
