Hi All, I'm new here, so forgive me if I'm asking for advice that's been given elsewhere. I own a couple Beretta .40s-w and I'm looking at getting either a new Glock 23 or maybe a Sig. Originally, I was thinking of trying a .357 sig, but the guy who I usually buy from more or less helped to talk me out of that when I went looking (again) today. I've seen on here that you can swap out barrels between the .40s-w and the .357 - does that hold true between the Glock 23 and the Glock 32? I like the idea of getting another .40s-w - one less type of ammo on hand, but I also kind of wanted to try something different, so that would seem ideal if possible. Are there any lefties on here who can tell me about their experience with Glocks? On Berettas, the safety is ambidexterous and the slide release is big enough to reliably activate with my index finger. When I looked at the Sig, the release is really small and difficult to activate that way but on the Glock it seemed fairly easy - but then again I've never done it actually shooting. Any feedback from lefties would be appreciated. Thanks in advance, this forum is great.
