I'll just start off the question with the fact that I have a G23 and want a 9mm conversion barrel. By the time I buy an unmarked LW barrel and have it blackened I am looking at $135 plus shipping. Local shop has a very early G19. It is beat to death. It is the first 2nd gen style with the model number stamped into the trigger guard. The front sight is gone. The internals all need upgrading. The frame has several cracks and chunks missing from the strong side magwell area. This probably came from being a carry gun. The frame looks unsafe and if I shipped it to Glock I know they would not return it. The slide and barrel are appealing because they would convert my G23 to 9mm in the best way possible. I already have all the upgrade parts on hand and plenty of sight sets. What should I do? Buy a G23 conversion barrel for $135? Buy the used G19 for $300 and salvage the upper? Buy the used G19 for $300 and send to Glock for a new frame for $??? Are they free? Buy a new LE G19 for $409 with 3 mags?
