Looking at a few used 1911s in particular the Ruger SR1911 and seeing if anyone has success in re finishing s stainless pistol like that with the Caswell product.

Never tried the product.

I use the Caswell stainless steel blackener pretty often for small parts.

Degrease well and blast the part with 400 grit for a nice matte finish.  Then wash in warm water and  oil.  

Unfortunately, I have had less than stellar results on larger pieces.  Mottled, uneven color and not much more durable than a coat of Rustoleum.

I do bluing and parkerizing with very good results but those don’t work on stainless.  Until I figure out how to DIY nitride, I’ll stick to Cerakote for stainless steel.

I have had a few stainless guns nitrided. Jet black and almost impossible to scratch. Wears better than almost anything else. Maybe tied with ion bond and hard chrome. Go that route.

I didn't think about nitriding services.

Any recommendations?

I used an industrial company here in the PHX area so I wouldn’t have to ship my guns. But I think H&M has a good reputation if you have to ship.
