RE: which .45
If your looking for a CCW pistol get the Glock model 30, light and smallenough for all day carry and is about the most accurate pistol out of the box Ive seen. That and a good IWB or a snug belt slide holster with an untucked shirt and nobody will know you are packing, for the more formal dress get an IWB with a j-hook style belt mount and you can tuck your shirt in, just takes a few more seconds to pull it out. Others do make good reliable pistols, but just not something to conceal and carry all day in a 45 acp.
