i have a 26 and 33, great guns imho, the 33 was my edc for a few yrs, still carry it some, accurate, very reliable (none of my 4 glocks has ever malfunctioned) light, easy to carry, only con is they are a little wide. other than a kahr poly (ie P9 or PM9) they are my fav carry pistols.
imho the kahr P9 and PM9 are lots easier to pack, they are lighter and thinner, less rounds though (7-8 vs 12), but they do carry better imho. also they are probably more accurate, just as reliable as the glocks. probably more expensive though....my very most fav carry pistol is the P9, like it a little better than the smaller PM9, but both are excellent.
but if ya want a glock, they are excellent also, just depends on what ya like.
FWIW i dont think the '35 is smaller than the 27, the 9MM platform glocks (ie 26,27 and 33) are the smallest/lightest glocks, though the '35 isnt much bigger/heavier.
also FWIW the 26 is easier to shoot than the 27/33, the .40 and .357SIG really "torque" in your hand more than the 9MM, just a thought. i got the 33 and then got another bbl. from glock and can shoot both the .40 S&W and the .357SIG by just swapping bbls, the spring/mag/etc is all the same, kinda neat. also added a glock "+2" floorplate and it now holds 11 rounds in the mag and has a nice extension for my hand, again, neat imho. note: only buy glock brand floorplates, the scherer/etc DO NOT add 2 they add 1. also imho glocks should always be carried in a holster (ie not slipped into your waistband) for safetys sake. another plus for the kahrs imho.
