The funny thing is that the glock is more expensive than other polymer guns, yet many of the others have it beat. A Walther is very similar to a glock, except with changable grips and a superior trigger and cheaper if you wait for a sale. The S&W has it beat by $80, and it is equal to a glock in everything but the trigger. You can get an HK(!) cheaper, although I think not in 45acp. I'd go with a .40 though if I were looking to equal the 357 round.

If you're going to go for a $550 pistol, why not its better at $500, or it's equal at $470?
