I was extremely impressed with this slide, goes perfectly onto 226 frame with no fitting. Now I can shoot 40 or 9 in less than a minute! Great value and super fast shipping as well!
Good Value for the Dollar

I have a Sig P226 in 357 Sig/40 S&W and wanted a 9mm conversion. This complete factory upper, fit perfectly, functioned flawless and is a great addition to an already excellent pistol. I had concerns about gunsmith fitting, but this upper was completely drop in....
Perfect!

I received my slide assembly two days after I made my purchase. Osage even called me after placing my order to confirm everything and let me know when it should be arriving. The slide came in brand new packaging and lubed up like my MK-25 came from the factory! I’ve now shot about 400 rounds with this new slide and it’s like I never replaced my slide!

The part came quickly and was well packaged for the journey. What I appreciated most was a purchase verification phone call. All told, the transaction went smoothly and Osage representatives were professional. Thank you.

New, fast shipping and fit my 357SIG P226 perfectly. Also bought a 40 cal barrel, and now it’s a three caliber handgun.
P226 Mk25 Slide & Barrel Combo Fit Like A Champ

I have a P226 I purchased in Germany when stationed there in the late 1980's. The slide is rolled and welded carbon steel with 'Made In W. Germany' stamped on the slide. I confirmed with Sig the milled Mk25 stainless steel slide and barrel were a direct replacement before ordering. As confirmed, the new slide and barrel fit my frame perfectly. If you have an old German slide don't hesitate to upgrade your pistol with the Mk25 slide assembly.
