I want my first glock for xmas. I am interested in the 32 (hence the screen name). I was unaware until I started browsing this forum that the calibers were interchangable. So let me see if I have this right: The 32 can be converted to a .40 or a 9mm. The .40 conversion is just a drop in barrel, the 9mm conversion is recommended to include a different clip, extractor, and ejector. Is that correct? I also read something about the conversion not being recommended with one generation because it isn't able to handle the extra power? thanks in advance.
