I have a glock 17 and was considering purchasing something a little bit smaller. I have really heard a lot of great things about the new .357 sig. Does the glock 33 have a thicker slide and is the frame thicker in order to withstand the constant 40,000 psi? I have had many people tell me that my 17 will last for over 100k rounds. Can the same be held true for the litte 33?
