Since I figured out that my 26 reliability issues were ammo and not gun related I’ve put about 5K rounds through a pair of Gen5 26s with zero issues.
Much softer shooting than a 43, easier reloads with a 17 round mag, much more reliable with full power ammo. Not much more printing as the outline is the same size, just a little thicker.
I actually went back to irons from an RMR on the 26 solely because the slide was difficult to manipulate with the optic taking up so much room.
