I’ve been trying to carry Glocks for the last year and had to buy a ton of new holsters because my thin build didn’t really hide them very well.   Glocks are thicker than most of my Sigs and carrying them in any other manor than IWB has been almost impossible if I want concealment.   I still love carrying them in Blackhawk Serpa holsters but these holsters are not CCW friendly in my humble opinion.  There are so many variables in trying to conceal a firearm and some modes are just not practical.   I’ve seen ankle holsters for Sig 229 and large Glock guns and I just find it unreasonable to carry that much weight on your ankle, not to mention how secure the thing is.

One favorite way to carry on an outside the waist holsters is with a 1911.  The 1911 is a much thinner frame and  even though the Government model is long, it is easy to tuck in and conceal.  You may have some issues with the cocked hammer snagging but that is something that can be dealt with.  Galco holsters made the Combat master which is a belt attached holster.  This holster is going to fit right up against you and not protrude.  If you add that with the thin framed 1911, you will have another OWB holster that can be concealed.  It does work with summer carry if you wear a large cut and dark t-shirt.
