I'm thinking about trading in my G23 for a G21 or G30. I've been wanting a .45 for a whole but don't have the funds at the moment. I don't really want to get rid of my 23 but I really want the .45. I'm torn between toughing it out until I can just buy the 21 or 30 an add to the collection or if I should trade. Also what do you think I could get on trade for my 23? It's a Gen 3. No mods except the lettering painted in on the slide and mags.
