Greetings Gents, I have several questions concerning the G32. I own a G19 and G23--both Gen3--and I think that they are premier CCW/Self Defense weapons. I am somewhat interested now in getting a G32 chambered in 357 SIG. It looks to be dimensionally the same size as the G19 and G23, which would fit in my current holsters (a cost savings). Certainly the same "manual of arms" between the G19/23/32 would be a major advantage. 1) Anyone know if a "Gen 4" version will be released this year? It looks like the G17/19 and G22/23 are slated for release (G22 already released). 2) Are all of my G22/G23 .40 S&W magazines compatible with the 357 SIG G32? I would think so, since generally speaking, both types of ammunition are compatible in the magazines with other manufacturers, such as SIG P226, P229, HK P2000, HK USPc, etc. (another cost savings?) due the same case dimensions. 3) Would it be possible, or is it even possible, to just get a G32 barrel and "drop in" my G23? Thank you in advance for your responses.
