Differences in a Cristobal and a Beretta 38/44 SMG?

[Turtlez06]

So I never realized how many rifles and pistols shot .30 carbine. There are so many more than I knew of till recently. Obviously the M1 Carbine, the Ruger Blackhawk, The Taurus Raging Bull, The Marlin model 30 lever action, The Kimball, and the rifle in question the Cristobal M2. So to all you gunsmiths out there, hypothetically what would be needed to convert a Beretta 38/44 smg to a Cristobal M2? There are parts out there but rare. I found a place that has the complete bolt assembly, ejector and bolt cam area, semi and full auto triggers, sear, rear cap and rear cap lock. Then I have also found a Beretta 38/44 smg non-firing but mostly complete and legal to purchase. It is a original item constructed from original parts sets on machined aluminum dummy receivers. Although having 90% original parts.

In addition to the San Christobal carbine there is a Beretta Made Model 62 carbine caliber carbine. This uses a magazine much closer to the normal US GI carbine magazine and is mounted almost vertically. No part can be interchanged with the San Christobal. The tube diameter on the San Christobal is the same as that found on other Beretta 9mm SMGs. There is a US sized tube that has the correct inside diameter and is big enough on the outside to machine the end cap retainer lugs. Most builders then reduce the outside to both lighten it and make it more correct. Tube is nominally 1.500" (actual 1.515") wall thickness is .165". The stock is normally a full length style, and you can see in photos the magazine tilts forward. The web site forgotton guns has some good info and may well be in the process of making a short run of specially modified guns limited to SEMI-AUTO ONLY. There are original guns in semi auto only but open bolt like the full auto guns. There are still a small number of guns overseas but because of the current barrel import ban even if they were to come in the barrels would be torch cut. In England there are a number of "deco" guns and show up at shows like "War and Peace". I just checked my web site, thinking I had a photo of one there but was a Beretta 38 series. The factory where they were originally made stopped making guns and made school desks and some other items before it was pretty much closed down. John Bush

John, thank you for all the information. It seems information on the Cristobal is sporadic at best. Most sites just have the wikipedia copy about the rifle. I am not looking for full auto rifle. I just really like the .30 carbine round it is so versatile. I thought it would be interesting to be able to see if it was possible to recreate a semi version of the Cristobal. I guess it is just one of those rifles that only the lucky few with access to type III weapons get to play with.
