Awesome firing pin stop!
Much less fitting than the previous oversized firing pin stops that I have installed.
They dropped right in to two different guns. I had to file a bit for ejector clearance on my Springfield Champion Operator (a 4" 1911 with an ejector that's more to the center of the cartridge, I suspect your HD-206 FPS for commander sized guns would have dropped right in, but I didn't want to wait) But other than that, thickness, overall width, extractor engagement were great.
Same story with my Kimber Super Match. Great width, length and extractor engagement. The Super Match has adjustable sights, so I had to work on the top of the FPS for the bomar-style sights, but other than that it was a drop in fit! Awesome. I was able to get both stops in my guns in less time that the other oversized stops take to get into just one gun.
