Maybe I’m not that experienced with carrying Glocks for concealed carry, but I often find them to be more comfortable being carried in a leg holster or paddle  holster.   The same goes for revolvers, I rarely see people carry any type of revolver in a holster.   Peoples tolerances for carrying can drastically vary due to body sizes.   When I got serious about moving away from a Taurus T85 38 Special and was looking for a durable semi-auto with more punch, but not much larger, I came to the conclusion that it was either the Glock 26 9mm or a Sig 239.  The Sig 239 won out because it was slightly thinner, but not really a lighter gun.

When you are deciding on a firearm, don’t worry about the weight of the gun.   If you get a good gun belt you shouldn’t notice weight as much as you will notice the size of the barrel.   I still find the 1911 to be one of the most comfortable guns to carry because it has such a thing frame and is balanced very well, but my Wilderness 5 stitch instructor belt supported it so well I couldn’t tell the difference between my Sig 239 and a 45acp full size 1911.  I tried on various Don Hume holsters, Galco holsters and Bianchi and found the Don Hume and Galco had a lot of good options.   It’s good to find a dealer that has  a return policy where you can try it out in your own home and then return it if you have any issues with the fit.
