If you could buy either the G23 or the G38 with ammo not being an issue for either, which would you buy? The gun will be used for ccw and home defense. I've shot both now and I can't decide...

Put a G37 mag with an A&G sleeve (or you could do it without the sleeve, I just prefer not having the gap) and your G38 is 10+1 or add a Glock +1 extension on it and its an 11+1So I'll reiterate my personal feelings on it.. I love a .45 and for home use or something I would stick to a g21 with a 13+1 mag... too big for cc though.. If Im gonna carry a defensive weapon of that size, it sure as hell better hold more than 8+1....
23. 2nd gen preferably. Probably my favorite glock of all time.
Why do you not like the 40 s&w? Just about every 40 s&w round seems to do quite well for self defense purposes. Its hard to find one that not good in that caliber. 45 gap is fairly new, and doesn't have much of a history. Plus its less rounds.I really like my G38 and dislike the .40S&W in general.
2nd thatFunny you should post this.. as I was somewhat thinking about this recently. I love (like others) the .45, but I just cant seem to get my head around the lack of capacity in a particular gun size.
I could never justify why I would carry 8+1 when I could carry 13+1 (.40) or 15+1 (9mm) in the same size gun... I mean those numbers arent even close.. 5-7 rounds different is significant, and I dont waste my time on any concepts of "I carry a spare mag". I have yet to have anyone ever (and I have asked for it) cite a situation when any single event occurred newsbound where a civilian CC self defense happened where the individual had time to swap mags (Again, throwing it out there, I would LOVE to have someone direct me to an article where this is verified ever happening).
So to me capacity is an issue when carrying a gun the size of a g19,23,32,38..
I have also shot all of the aformentioned calibers and the only significantly different one to me is the 9mm (being lighter) whereas the .40, .357sig and 45gap all feel basically the same IMO.
So I'll reiterate my personal feelings on it.. I love a .45 and for home use or something I would stick to a g21 with a 13+1 mag... too big for cc though.. If Im gonna carry a defensive weapon of that size, it sure as hell better hold more than 8+1....
