i am not a fan of the beretta's 92 series, and da/sa guns. but they do work and they are reliable and have the possibility of being accurate but they are not my first choice, especially out of the list that you have. also they are just to big for my hands and uncomfortable to shoot.
i say get the glock 19, i wish i still had the one that i sold and i am sure that i will get another one in the future. they are an all around great gun, they are reliable, accurate, replacement parts are cheap and easy to find. they are easy to shot and maintain and there are gobs of acessories out there made for the glock line. the 17's are great and the added barrel and sight radius would maybe get a little more accuracy out of it, but i would take the 19, you might get it and descide that you want to carry it, and then the 19 would be the best choice of the two for that.
i so go for the 19
