glock 26's (and 27s and 33s) are imho some of the better edc pistols around, being surpassed imho only by the poly kahrs (P9 and PM9) for an easy to pack lite accurate dependable edc pistol,
i wouldnt change anything on one, if it was me, though i usually carry ranger 147gr in my short bbl 9MMs i have shot a fair bit of +P+ 127gr ranger thru my 26 with no problems, none at all, as far as recoil, its a 9MM, imho no 9MM is a big deal in the recoil dept, they do have a tad more blast but again its nothing like a 33 with 357SIG ammo in the blast or the recoil dept, the .40 also is a lot more of a kicker imho, or perhaps torquer would be a better word, the 357SIG and .40 both tend to torque in your hand when fired, especially with no grip extensions (the glock +2 floorplate is the only way to fly as far as grip extensions go imho, and i have tried them all) but the 9MM is a pussycat in comparison and is easy for most anyone to shoot and shoot well.
i have always thought a 1911 style safety would be a good addition to glocks in general but i am in the minority on that, and you really dont have to have one as long as ya carry the thing in a holster and use a proper manual of arms (ie keep finger off trigger unless ya want to fire), some folks carry 26's in there pocket, no holster, man in wouldnt do it, i personally know of one guy who was jamming a glock 23 down the fron of his pants, no holster, and it caught on something, belt bucle, something and fired it blowing off his big toe in the process and getting a bit of a powder burn on more important parts lol, ruined the pants of course, i always carry a glock in a holster myself.
as safe as a DA revolver, or a DA style auto like a kahr? no way, the trigger pull is way liter on the glock than the DA pull on anything i have ever tried, i mex carry my kahr P9 all the time and pocket carry the PM9 sometimes with no holster, i would never do that with a glock, if you carry a glock it needs to be in a holster, plain and simple, well if ya carry the thing with a round in the chamber anyway. imho comparing the trigger on a glock with a DA revolver is apples/oranges, not the same thing, now a single action auto or revolver, thats a lot closer to being the same thing, the glock trigger just doesnt have that heavy pull like the DA stuff.
