Marks on breach face MK III 22/45



Log in to see fewer ads
I've noticed these marks on the breach face right above the chamber recently. Seems like the bolt face is causing this. I don't see much wear on the bolt other than a small nick on the left side. Gun runs great. Thinking maybe I need to put in a new recoil rod assembly? Appreciate any comments.

That mark is fairly common on MKIII breeches. It comes from having to pound the bolt stop pin into place. The pin will launch the recoil rod forward so it peens the breech.

My first MKIII had that mark right from the factory, and the end of the rod was splayed and cracked. I had to repair the rod before I could even take the pistol to it's first range trip. Yours looks to be in pretty good shape.

As far as the dent in the breech, the damage is only cosmetic and shouldn't continue to grow much over time. If your pistol still needs the bolt stop pin pounded in - keep an eye on the end of the rod for a while. Touch it up as you think it needs to prevent spitting.

I ditched my OEM rod assembly long ago in favor of the Volquartsen VS-3 unit. It doesn't contact the breech and you can change recoil spring weights to tailor the spring to your ammo as well as replace a worn out spring.
