Hi Power Hammer Follow

Sounds to me like some wannabe "gunsmith" tried to do a trigger job.

Odds are good you need a new hammer, sear or both.

Take it to a competent gunsmith.

+1; your gun needs professional attention and some new parts.

I have a Mk3 that was doing the same thing. I went through 2 new sears only to find out it was a Mainspring issue. The mainspring applies pressure to the sear which engages the hammer "hooks" a weak spring will allow the sear to "jump" out of the hooks when jarred by the slide slamming into battery. My gun was factory fresh and not gone through by anyone when this started to happen. I bent the sear leg on my mainspring and haven't had a problem since. I have thought about getting a new mainspring though.

I would not jump the gun on the kitchen table gunsmithing theory just yet.

It could be a mainspring or recoil spring issue too. These are cheaper fixes if trial and error are your way of testing to see if symptoms go away.

Regardless of all that.
If the hammer has been dropping to half-cock for any length of time, the damage to the hammer hooks and sear edge has already been done.

I would suggest a complete strip-down and inspection of the hammer & sear for damage regardless of it it turns out to be a weak sear spring or not.

I'm so glad to find this fresh thread up. First, my KBI HP clone had the same issue, and I was told that the issue was most likely a worn "sear". Now, to ask my question. I found my late uncles feg today, and the mag release is not working. unfortunately it had a full mag. i jacked it empty, and stripped off the slide, grips, and mag bottom off so now I have a frame w/ an empty mag body stuck in it. the mag release screw started to strip as soon as i applied pressure to it, so I've stopped, and now await advice from someone more knowledgeable than myself

:banghead:
It's not a screw!!!
It's a lock plunger.

If you were able to push the mag release in all the way, the plunger would turn about 1/4 turn one way only, and the whole mag release, spring, and plunger would fall out as a unit.

I would apply penetrationg oil and plastic hammer to the mag release button and get it freed up.

They only thing it can be is dried oil & dirt have glued it in place.

sorry RC, I'm not a gunsmith by any stretch. I just would like to get it cleaned up, and functional again. I'll get on that when I get home. Thanks

only les than ten times.

Probably not damaged much then.
I got the impression from your first post it had been doing it for some time.

The cracked FP stop would have no effect on hammer follow unless the bottom part broke and is not able to fully push the hammer down far enough to be caught by the sear.

the person who sold it to me that some "work" had been done to it.

It seems the first thing to check would be the hammer hook depth and sear angle. If it appears some shade-tree gun butcher attacked it with a bastard mill file you need some new parts.

The other thing to check would be proper tension of the flat lief spring that pushes the sear into position. Perhaps they took and bent it straighter (less tension on the sear) in an attempt to lighten the trigger pull?

Also, while you have it apart, make sure it isn't packed full of dryed oil & dirt. That could possibly build up on the hammer hooks and not allow full depth sear engagement.
