A CZ 2075 RAMI is a little smaller, and more ergonomical. If you like the Glock-action trigger, with no safety, then have fun. If you want DA/SA with a safety, get the RAMI. My wife loves her RAMI.
Also, czeck out the CZ75 PO1, if you can carry a slightly bigger gun. With the CZ standard cap mags, you can have 15 rounds on tap.
If you are wedded to the idea of 45, the 30 is one of the most compact 45s on the market, and the one and only Glock I actually liked shooting.
If you must have 45, and, like most of us, have a low budget, look at the EAA Witness line of compacts, as the compact Witness 45 is a very good all steel gun and lower priced pistol, although heavy. The Bersa Thunder 45 has a good following, too.
Go to whatever rental range is nearby, and try several differant pistols before buying - save much grief and financial pain later....
