Has anyone out there had any experience with the 22 LR conversion kits for the 1911 pistols. I have the AO Model 1911 WGS (Deluxe). The most convenient shooting range we use here in FL is cheap/hour but they require you to buy their ammunition which is not cheap. I've read a number of reviews about these conversions which are mostly positive but I still have reservations. Using 22 caliber ammo would certainly make the practicing easier on the pocket book. Anyone with conversion experience with AO 1911 either positive or negative?
