I use a Hanks Gunner belt and a Galco Triton IWB with a G17 at 4 o'clock and this works well for me.
The key as some have said is use a good belt and a good holster with full size guns.
Pretty good article. I've shot with Joe Chacon and had work done by him, he's a great smith. he's also co-founder of Auto Benchrest Association, I really like shooting those matches.
