A few days ago I purchased a set of AmeriGlo I-dot pros for my g19. Before I left the store I went ahead and had him order a set for my g17. Yesterday I traded a M&P for a Gen 2.5 g27 with 6 mags, and a calco IWB holster. I am going to shoot it tomorrow and see how I like it. Now I run into a problem, which gun gets the night sights? The g17 is my primary HD gun, while the g19 is backup for that. The g27 may, or may not take over as my primary carry. Right now my primary carry is a g19, but once summer comes around it will be my Kahr CM9. I should also note that the g17 is my competition gun as well.
