    Hey everyone, I may have humped my self and am hoping someone here knows if I have a way out?
    I picked up a 1377 in pretty good shape and may have slightly overpaid but not bad. PROBLEM lies in that a ordered a steel breech before it arrived and now find that I have an older "sliding cover" style pistol, all the breech kits say they will not work with these!!!!! So can I mod it or do I eat it?????
    Thanks all,
    Be well

    I'm remembering it being doable but quite a bit of work to do a full conversion. I do believe you can simply bolt the steel breach on tho you will also need a transfer port, and other stuff.
    I'd probably sell THAT 1377 and buy a newer one for your steel breach.

    Only need three more pieces, New barrel, T-port, and T-port gasket. The old 1377s had a different feed angle and slightly different chamber length to the barrel.

    Thanks for the info! That being the case, at this point could I do a 22 conversion with a new barrel and bolt/probe?

    Yup. Barrel and bolt are all that's required. You can even buy a new barrel band and add a longer barrel.

    Do I need a transfer port? I hear of something called an evo mod but can’t find any details, I think it has to do with the tp.
