Appendix carry a Gov't 1911? Wow. I'm impressed. I tried it once...just no way I could get used to it.
I started messing with it really as a purpose driven mode, i.e., a better concealment mode on those few and far between more discrete carry days, which usually entail carrying my M&P Shield. Once I got used to it though, and found the right rig for me, I prefer it for everything. The thing with appendix carry is you have to find the right rig for you. As popular as the CCC Shaggy is as an appendix rig, I simply can't use it, just won't work. Tried the JM Custom Kydex rig and had a winner, and I've also become a fan of the G Code INCOG. As far as carrying a full size gun appendix goes, I think in a lot of ways it's easier. The additional length helps keep the butt of the weapon tucked into your body, where a smaller gun can tend to roll outboard on you. For that reason, a lot of guys that AIWB a Glock 19 will do it in a Glock 17 holster.
