I'm looking to do some plinking with some of the mainstream pistol ammo. either 9mm , .40 , or .45acp . I would want a barrel for an encore in one of these calibers. 9mm would be best because of the price of ammo. but all 3 would do. My question is, where do i find the barrel i'm looking for? I would like to have SST w/ no sights, just drilled and tapped. Even a shorter barrel than 24" will do, but i do wnat it to be a rifle. thanks everyone!
