My 2 cents...
I've owned and shot both pistols. Both shoot like a dream. Never had any problems with the two fingered grip on the 26 as far as shootability goes. Glock's got the ergonomics down pat.
My issue with the 26 was the notion that in the tense adrenalined rush of a situation where you might have to draw your pistol in self defense, the odds of FUMBLING the 26 with that two fingered grip were much higher. It conceals much better, shoots just as well, but the potential fumbling factor led me keep the 19 and sell off the 26.
Actually, I carry a 23 these days! :-)
Good video.
