The difference between a P-38 and a P-1 is that the P-1 has an alloy frame. The Chinese Tokerevs that I've owned were 9 mm , crappy workmanship but they all shot well. I find the comments about 7.62 x 25 hard to believe, if some one told me the ballistics were similar to a .357 Sig (which it resembles, being a bottle necked pistol cartridge) I would find it easier to believe. Comparing it to a .357 or .44 Magnum seems ridiculous.
