dont have a Gen4 26, have 27, but they are a great little compact weapon, should be fine have not heard to many issues with the G4 G26... just enjoy it and get use to the small grip...
Actually, mag extensions only give more length to the front of the grip; the rear of the grip, which is the culprit in regards to printing IWB is NOT lengthened. Thus; I don't find the G26 with mag extensions to be totally comparable to a G19 in size and weight. I personally find the G26 better from me for IWB; without any mag extensions on it. I have A UBG Canute holster for both the G26 and G19. The 19 is quite concealable under most circumstances, but the 26 is even more so...YMMV. Regardless, I won't get rid of either of these guns; they are both top shelf self-defense pistols. And I might add; I do sometimes slip the G26 into a Mika pocket holster when I am not wearing covered IWB and go run my errands in Wally World or whatever. It's a load in the pocket for sure and I wouldn't want to carry it that way all day, but for quick in and outs, it works okay.If you use the mag pinkie extensions on the G-26 you will find the size and weight difference between the G-19 and G-26 almost negligible. Therefore if you are going to use it for the range, and also IWB carry, you might as well just stick with the G-19. In my mind both of these pistols are top shelf, but for my needs, too big for easy comfortable carry. The G-26 is not a pocket pistol. I prefer something a little thinner and a little lighter such as the M&P Shield.
