Default It's here.

Thank you CMP!!

My CMP 1911 arrived today. First, let me apologies for the lack of photos. I'm 65 and internet challenged. I'll post pics as soon as my daughter helps.

Anyway, my 1911A1 has a RR slide, Colt bbl and Colt frame, #835xxx. From what I can determine, that places the frame in 1942. It's an AA rebuild and it's in very nice condition. It's not pristine, but I wasn't expecting that.

I do have a couple of questions I hope someone can help me with. On the right side of the slide, to the left of the serrations there is the stamp "MB". Also, on the right side of the frame, underneath the slide stop pin, there is the stamp "A777". I've seen a variation of that on several photos of CMP 1911s. What's that, and the "MB" mean?

Thanks for the help, and photos coming soon.

the A777 has been guessed at being A (some repair site, perhaps, but not likely Anniston) month 7 in 1977 7-77

The MB I would guess is a rebuild marking, but would have to look in my books which are several feet away (I am eating dinner and will look in a bit)

CONGRATS!!

I have been told on another forum, were I first saw pictures of the MB stamp on current issue 1911a1s that it meant Magna particle inspected or magnafluxed can't remember which. It's something they are apparently doing with the slides

Yes, I could see the "MB" or some designation on new slides. Maybe the armories did this when certifying the pistols for service pre Gulf War"? Being this is a WW2 RR slide and the stamp "MB' looks like it's been there a while, I'm curious. Bottom line, I don't care. I'm very happy with my 1911.
