Bought a Suomi awhile ago, and finally got to get to the range. Its a heavy gun, almost no recoil. Its a pleasure to shoot, I could have shot this all day. It ran well for about 150 rounds then started to jam. I noticed that the bolt is parkerized, i'm thinking as it heated up it started to stick. I might try to polish it and see if that helps. (any imput would be appreciated) I was using stick mags and coffin mags. I like the quality of the build, parts fit well and the welding job is very good. Im glad I bought it. Here is the Suomi, and me shooting it at my range. It was a fun day.
