Well I just had my first slam fire today and it scared the sh** out of me. I was shooting a Springfield Trophy Match with comerical re-loads. It not only happened once but twice in one box of shells. I put in a fresh Mag and let the action lock up, and that is when it happened. The primers looked to be seated ok, I just put in new Wolf springs in the gun, any ideas as to why this would happen.
Thank You Keith

Hello. Did you put in the Wolff replacement firing pin spring as well?


Best.

The last time I heard someone think they had a slam fire, it turned out to be hammer follow when they dropped the slide. Unless your firing pin is protruding out the firing pin hole (and if it was, you probably wouldn't have been able to chamber a round), its not really likely you'd get TWO slam fires in 50 rounds.

However, if your trigger is excessively light or you've got some crud between the sear and hammer hooks, it is more likely that you experienced hammer follow and the sear didn't catch the half cock notch in the hammer. Have you done anything else recently with the trigger/sear/sear spring?

To answer some of the questions. Yes I did replace the fireing pin spring with the new Wolf also. I have never done anyhing with the trigger, nor have ever taken anything apart in that area. I bought this gun new in about 1997 and have shot around 1500 rounds thru it so far. I agree it sounds more like follow thru. What should I look for?

Did you put the new firing pin spring in properly? Small end first.

Like JohnL suggested, I'd take a look at the firing pin spring too as something may be incorrect there.

Assuming that passes, the way to test for "hammer follow" is to drop the slide (from slide lock) on an empty chamber. NOTE: don't do this a bunch of times, just a few (3). If it follows any one of those times, it's likely that's the problem.

I once had a Kimber that apparently had a incorrectly heat treated sear pin that started to bend about 1000 rounds and it did exactly this...hammer follow.

I agree with Vapors. You had best consult with a 'smith, or at least someone who knows how to do trigger jobs. I just do not believe you had a slam fire with that new spring, backward installation or not. I'd not wait too long 'cause next time you may be holding onto a full auto .45 and that's not a lot of fun.

May be that you're pistol is finally breaking in and there isn't enough tension on the sear spring...I had some problems with premature wear on some of my SA Loaded Champions' parts and frame. I tried holding the trigger itself FORWARD while releasing the slide and VOILA'...the trigger itself was flopping around...Increased the sear spring tension a bit and the follow disappeared.
I think you should have it checked by a 1911 smith and contact SA immediately before you get in a bind...They are quite good about fixing their products. Do you have the contact information? Let us know what you decide and the outcome! Good Luck and be SAFE...
