I had a HK USPc 9mm... Wayy to big to carry. Traded it for a glock 27.
Those Glocks don't look so big but they are. My G27 can sometimes be alot to carry. Hence why Im getting a BG380 for pocket carry. Wanna enjoy my time out and about instead of having that glock grip against my stomach. I have a good desantis leather holster with it that makes it pretty comfortable, carrying a gun like the G27 or any other subcompact feel good once you get used to it.
Good luck carrying a G23. Many pull it off (hell sometimes I carry my brother G19 which is the same gun as the G23) but I highly recommend you at least go down to the 27 if you intend on carrying a big gun. The 27 is bigg enough trust me... Comfortable carry insures you carry all the time! I'm still going to carry my G27 around thats why I recommend it to you. But my LCP is going to be with me where my G27 cant go.
