Day 2 of wearing my 2 inch SP101 in a Smartcarry. I believe this may be the method I use from now on, I don't see myself buying any other type of holster for the SP101. The S.C. works very well for me in a small revolver like the SP101. I do highly doubt that this method will work well for anything larger than small handguns however.
If you're considering a Smartcarry, hold up your unloaded pistol in front of you just below the beltline. If the end of the barrel does not protrude down below the pants seam at the crotch, then you can likely wear that pistol in a Smartcarry. I recommend them highly.
I've also practiced drawing and am fairly fast at it. You do need two hands to re-holster.
