Congrats on the buy bud. Turned mine into the most souped up 57 ya ever seen. Got the CSM MP57 chasis installed along with extended mags and tandemkross trigger. Paired with a SIG Rattler brace. And it's a killer little PDW. you may wanna get some turtle wax spray and disassemble the mags and spray them down good inside and out. Will help that plastic follower alot to feed reliably. Also will help empty mags drop better and keep rust away etc. Made a few quick videos on YouTube if ya wanna see it. Search ruger mp 57 conversion and you'll see them around. But I keep hitting Academy as much as I can and believe it or not they get a little here n there for like 37 a box for federal and a little more for FN. found it more often than I found 9mm belive it or not. But I have a ammo box full of it now. I'd like to shoot it more but yeah it's kinda hard till I get setup to reload em. Can't wait to custom some hot rounds for it and see what she can do. Wished Ruger or someone would hurry up and sell some aftermarket barrels to choose from. I'd like one a bit longer and threaded. Next week or so I plan to drop it off with a buddy and get mine threaded. It's my new car/lunchbox gun so I want to at least have a blast can on it for if I have to use it without ear pro on.
