I used a semi auto 45 ACP Uzi bolt with a 9 mm Uzi extractor. It was a perfect fit.

    that sounds like a better blowback set up for the 357 sig.

    one of the problem areas for the 357 sig conversion would be the rather expensive ammo. a semi carbine would eat a bunch of it!

    a 40 or 357sig would certainly have some advantages in a carbine!

    40 S&W will work in the 9 mm Uzi magazines. There may be a custom barrel available or one would have to be made. The semi auto 45 ACP Uzi bolt fitted with the 9 mm Uzi extractor is perfect for 357 Sig and 40 S&W. For whatever reason the 41 Action Express magazines are not great choice. The Uzi 9 mm magazines are similar to the 9 mm AR15 magazines.
