but just to discuss the mechanics of it. I think it could be a big encouragement to those trying to carry for the first time today.
Having carried dozens of different guns over the years, I would say that you can carry just about anything; if that "one gun" is what you want to carry.
Looking back, I would say that probably the one biggest "issue" that has driven my "carry evolution" is that of sitting comfortably. Some of my solutions over time have included (for longer barreled hand guns): cross draw OWB rigs for 6" .44 mags and the like (carried several different .44 mags for many years this way relatively quite comfortably), vertical shoulder holsters, and high ride OWB strong side holsters for Government size 1911s and similar sized autoloaders.
The other solution to the "sitting comfortably" issue is carrying more 4" guns; as opposed to 5" and up. The shorter barrel length can make a huge difference, and I am 6' 02" and 240 lbs.
With all this said after many years of carrying, I still prefer strong side OWB with a good leather holster/belt combo. If you were to see me today I would likely be carrying either: a Colt in either Government (10mm auto or .45 acp) or Commander (in .45 acp) or a Glock 29 (in 10mm auto) in just that way.
I have different hand guns that I have tried in a variety of ways (IWB, pocket carry, off body carry, chest carry, etc...) and pretty much have settled on OWB strong side with larger to full size hand guns; with the occasional IWB for Government 1911s or a pocket pistol in my front pants pocket, only if the dress and situation really dictate it. But, I live in Alaska and concealed is pretty easy pretty much year round. However, when I travel down south, still carry where I can, with the same holster/gun set ups as at home and never had any problems.
