Parts in Petri dishes. P35 on the left, P220 on the right.









P220 Elite Dark. Mostly the same work as Moran, but with more trigger work. Detailed review to follow.

Some before pictures and thoughts:

1. Lots of the same stuff as Moran had. This has a MIM hammer. I see no reason to change it, and hardness was 36 on the C scale. Softer than I'd like, but we'll fix that by coating it.
2. Same sear as the SRT in Moran. Needs truing badly, as can be seen in the picture.
3. The hammer strut wasn't polished like Moran's. It's actually a bit rough.
4. The mag catch was an order of magnitude easier to remove than the P229.
5. The frame is wonderful, like all SIGs.
6. The slide is wonderful, like all SIGs.
7. The barrel is wonderful, like all SIGs.
8. The extractor is the short MIM version. It's not flat :| Hardness is around 27 depending on the location.
9. I'm going to work on the beavertail a bit. Lots and lots of material there to fool around with.
10. Who puts threads into aluminum??? Needs helicoils.
11. Stamped parts were in the low 20s in hardness.

Gun is typical SIG. Just a lot nicer than most production guns in my opinion.

Bill for the extractor you can get a tool steel extractor from grayguns

Why is there two hammers in the P35 petri dish?

Why is there two hammers in the P35 petri dish?

Need to separate the hammer from the spur. The factory hammer is being scraped.

Double strike capability on a SAO... obvious.

One looks to be the stock hammer and the other looks like it is the replacement. A Warner, no doubt.

Very nice, Bill.

I love P220s. I really do.

Bill,

I am guessing that your coating will reduce/limit rail wear on the alloy frame (due to its hardness)? Since you are stripping of the Anodizing, pre-application, I assume it could be applied to an older frame to arrest rail wear that has begun on an older gun. True?

Correct. This finish will arrest all wear of the aluminum frame.

I can "build up" to about 5 or 6 thousandths without any trouble, if existing wear is an issue.
