I was really holding back on getting the ATI stock for mine, didn't want to dump a lot of $$ into a cheap, fun gun. ATI stock at Dunhams in IA, closeout $35, came home with me.
ATI stock doesn't flex like the factory one and adds a little heft to make the gun seem more expensive.
Mine likes all 9mm but I like the 95 grn Magtech and 115 grn Fiocchi from Sportsmans Guide.
Good price on your gun, fun to shoot.
