Hello, im new here. im not really into handguns, but recently i came across this crazy looking revolver with a "square" barrel. the old man didnt know much about it other than it was a .38. looking at it i found .38/.357/9mm on the barrel. i thought it would be cool to have 9mm revolver, so i ended up trading him a 12-ga 870 for it. from what i can find, it looks to be some gun called a medusa. i cant find much info on it, other than a couple of old, small articles. it shoots .38 spl, .380 acp, and .357 mag nicely, but its very picky with 9mm.. i have a ton of brand new german 9mm that fires great in other handguns, but doesnt quite fit into the revolver. even with brand new winchester rounds only a couple will fit out of a whole box. i have a friend that reloads and he told me the german rounds look slightly "glocked" and there is a special die that i can buy to fix this. so my plan is to shoot new 9mm out of other guns and make reloads specifically for the revolver. so i guess this brings me to my questions... does anyone else have one of these revolvers? do you have any trouble shooting 9mm? what is this special sizing die called? did i get a good deal on my trade? any other help/info would be greatly appreciated!!
