Small and lightweight, go for a Colt Officers Model or Defender, or Kimber CDP 3". Springfield Armory also has their scaled down 1911 frame guns in 9mm, 40 or 45 GAP. The Glock 36, Kahr Arms PM45 or one of the Para Ordnance D/A 1911 officer sized frames. Just depends on how compact and whether you want D/A or S/A autos. A 45 ACP pistol has to be a certain sized frame to accomidate the cartridge and magazine, so you just can't go too micro sized. If your hands aren't capable of handling those frame sizes, you may want to check 40's, 9mm's or 45 GAP's. I just don't care for the GAP Catridge, not because it doesn't work, but because of ammo choice and availablity.
