I ordered a EGW 70 series SS oversized fire pin stop to see for myself and have to say that it was well worth it.
I got mine yesterday and installed it in my SA Trophy Match. I just got back from the range. I was amazed at the difference on accuracy and muzzle flip.
The install was easy you just have to take it "SLOW". I used my old fire pin stop as a guide. This was my first time doing this.
Thought I would share this info for people that have never heard of this modification.
I'm using the EGW stop on one build and a Wilson Combat on another. The "bullet proof" (I believe that's the modifier) Wilson FPS is also flat, and requires a little less fitting. The stainless version of the Wilson I received has a very small radius on it. Come to think of it, I'll have to get out my radius gauges to see if I can measure it.
Note that the small radius FPS is to be used with a 23 lb mainspring ("hammer spring") and 15 or 16 pound recoil spring.
