I own and have carried a 43, 43x and now 26 MOS.
I was just having this conversation with a co-worker about the progression of CCW/EDC. Started with a 27, went to the 43, then 43x, and now a 26 MOS. What’s old is new again.
The only appreciable difference is in the slimness of the 43/43x/48s. This will be dependent on the person and their body type, but I can definitely tell a difference. Not so much that the 26 is uncomfortable but enough to notice.
For me, that’s the only real advantage of the slimlines. The shoot ability of the 26 is something that is only understood when you have a chance to shoot it, especially coming from a slimline. The 43/43x feels great in the hand but is not fun to train with. It is the only Glock frame that gives me Glock bite and I don’t even have large hands. The 26 however punches above its weight and really does feel like a much larger gun when you shoot it. The baby Glocks are arguably the most versatile guns in the lineup and when I threw an MRDS on the 26, it really changed the game for me.
