Things I liked: Very comparable to a .45 1911 in weight, feel, and operation. I think practice will transfer (exc. mag handling and double action). Very accurate in single action. I'm happy with the rounds per CO2 cartridge.
Things I would have changed: The spring device that retains the thumb safety comes loose easily and is plastic/fragile.
What others should know: Beware of trying to use grip scales from a Government 45. It looks like they will fit, but they don't work unless you want to do pretty extensive modifications. If you want wood grips, buy the model that has them -- there's a reason it's more expensive.
