What modern cartridge does one shoot through the 38/44? Is it .38 spl, .38 spl + p, .357 mag? Or all of the above? This sounds like an interesting revolver, as the heavier frame would take a lot of the "kick" out of a .38 spl. compared to, say, my Model 10-8. And is there a modern model equivalent? Please excuse my ignorance, and thank you in advance. Jeff T., PGH PA
