Glock 30 hands down. .45 acp, legendary glock finish and reliability, small enough to carry easily, and shoots awesome. Whatever you do, don't go with the 36...they are known to have many problems with the mags and improper feeding resulting in jams. The size difference between the 30 and the 36 doesn't merit the risk.
