Has Sig ever made a MK25 in 40cal? local guy has a
Sig that he says is a MK25,40cal, no box or paperwork ,no anchor on the slide.

Seems like a P226 chambered for 40 S&W that was common enough at one time. What would make it a MK25 without the special markings?

As I recall (vaguely) in the beginning those special “real SEAL” guns had things like “coated” internals and Parkerized, chrome-lined barrels as well, but I believe all that was dropped after a time. FWIW I never heard of a 40 MK25.

No such thing as a MK25 in 40.
All P226 Navy/MK25 pistols are 9mm.

Could possibly be a MK25 lower with a 40cal upper, but then it's not really a MK25 anymore.

No SKUs for 40.

Thinking the lack of an anchor on the slide or no mention of the QR code isn't working in his favor.

If he can produce the QR label, it will have the caliber noted.

I only know of the MK-25 being chambered in 9mm Para or 9x21 IMI.

Why that cartridge? Who/what agency had those?

The MK-25 was chambered in 9x21 IMI for the Italian market.

Thanks. I knew the cartridge was acceptable in Italy but did not realize that the pistol was sold there.

MK25 had a different rail. The early “Navy” models were rail-less.

Ah, yes. I knew about the rail-less models, but was not aware or forgot that the later rails were different.
