Frankly, in summer weather, and we have long, hot summers in coastal Texas, I would rather hide a full-sized 1911 than a Glock of any size, due to the Glocks' chunkiness and rearward-protruding slides, assuming OWB or IWB carry at the hip. I did carry 1911s 24/7/365 for several years, so this is not idle speculation. I found my G27 just too darned chunky; the outside rear corner of the slide printed against my cover garments unless I wore something really thick and full-cut. A sturdy T-shirt is enough to hide a 1911, on my body at least.

That is what I did, after I found the G27 too chunky. I had one SP101 snubby already, and added another. (I added yet a third one a short while later, and just recently acquired a fourth one with the longer barrel.) Ten shots, spread among multiple weapons in case something went wrong with one weapon. Moreover, my hands fit the SP101, so I shoot them better than I shot the G27 and even my G22, which was my duty pistol at the time. One could be worn at the hip, in my customary, default, 24/7 carry location, and the other could be in a pocket rig, for the "walk with hands in pockets" mode when passing through an area perceived as unsafe.
