I bought one with the adj sights over the weekend. It's a 9x18 cal. I stopped by the range on the way home and shot 100rds. The ammo was some type of surplus with aluminum cases. I hadn't cleaned the gun or lubed it before shooting and also didn't have a screwdriver to adjust the sights. I had 3 failures to eject during the session that I hope was ammo related. I ordered some Russian surplus ammo from ammoman.com. Anyone had experience with this ammo? Anyway its all cleaned/lubed and ready for when the ammo arrives. If it is as good as the 380cal mak I had years ago I will be satisfied. Russian Mak owners please share your opinions with me. Also tell me what kind of ammo yours likes. Has anyone tried the GA Arms JHP 9x18 ammo? Any feed problems? Thanks.
