Just got my first can for a Sig Mosquito. Kind of neat. What is out there for a short 45? I have a 3" and a 5" Kimber in 45. Who makes a bbl for the 3" model with threads already on it. I really don't want to mess with the 5" gun because it has a 460 Rowland conversion on it sometimes and the factory bbl is VERY accurate. I figured with the added length of the "can" the 3" gun would better size rig and more fun. Any suggestions welcomed.
