I have a nice pair of SA 1911 pistols that have been mildly warmed up and both shoot better than me. I want to convert one of the pair to 22LR. Ciener, STI, Advantage, WIlson, OEM, re-packaged, ready-to-shoot, need to lap-in the slide, magazines work great, buy only Kimber mags, will feed any ammo, use only the good stuff, $249, $515 etc.. It's all sorta confusing. I want the best shooting setup. This gun will stay converted, so no need for a 20 second change over. Anyone want to set me straight? Thanks!
