I just got my preorder Vanguard 2 holster yesterday and I really like it. I am, well no sugar coating, fat and this is the most comfortable IWB holster I have tried so far. I carry at a 3 o'clock position because it is uncomfortable to carry in appendix and it seems to be the most comfortable and useful. Up until this point the most comfortable holster IWB that I had found was the Crown Jewel IWB holster. I have tried stuff from crossbreed and galco, Raven Phantom inside the waistband, Crown Royal with IWB clips and loops, and a few others as well. When I was carrying a smaller gun I used a Crown Royal type that he made for me for my LC9 and that worked well, but when I switched to a Glock 19 IWB the holsters I tried rode higher and pushed on the magic love handles/spare tire and pushed down on my pants so they were constantly at an angle and I was always pulling my pants up. The Jewel solved this problem by sitting a little bit Closer to the belt line and has been quite comfortable for the last 8 months or so that I have been wearing it. The Vanguard 2 sits a bit closer to the belt line like the Jewel, but because there is even less material it just seems more comfortable to me. I wore it all last night and today and have done a lot of drawing with a blue gun and my G19 and it seems to hold the gun well. So, while i work on being less fat this seems like the most comfortable option for me right now. I know comfort is not the only reason to use a holster and carry a gun, but if it isn't comfortable it makes me less enthused to wear it all day and my safety is important to me. For training purposes at the range I will probably still use the Jewel some since it will be a little more efficient and easier for reholstering and it carries the gun in just about the same position. I have serrations on top of my slide and enhanced side cuts front and back and I don't feel anything digging in through my undershirt or underwear. If I was going commando it might be a little different.....
I will update as I wear it more and when I go to the range to do some shooting with it.
