Hi,
I've been carrying my SP101 for about 4 months now. I tried a few different holsters for CC and most of them found thier way to "the drawer of no return" lol.
Truthfully, the holster I like the best and conceals the best is a $20 Desantis "Insider" I bought at my LGS. The package had a small sticker on it that said "Custom". I checked the Desantis website and they don't list an "Insider" for the SP101. So, perhaps my LGS had them made special? I don't know, but they had a rack of them there.
I wear it "appendix" at about 1:00 in the front. I found this position to be the most comfortable. Since it rides so low, I don't feel it dig in my gut while sitting. Also, in the appendix mode, I find I can bend, lift my legs and rotate my upper torso with NO problems. I find it so comfortable that I forget it is there some times.
Here is the SP101 in the holster..
Here is a quick picture I just took of the holster on myself.
I did not change anything with the gun itself, it is bone-stock. The factory grips are the best for concealed carry while retaining a very good feel while shooting.
I tried the Hogue Monogrips after reading so many good reviews of them... But, my experience was opposite then the majority. I found them to much worse for felt recoil, concealed worse and made my accuracy drop off the map.
I found the sock grips to point naturally for myself, where as the Hogues pointed downward due to the combination of rounded back and the finger grooves. I had to adjust my wrist angle, which made my wrist roll even more during firing .357. For the first time ever I missed the paper and the cardboard backing while at the range! Not only that, I bruised my web area of my hand! These things NEVER happened with the stock grips, so I put them back on and the Hogues are in "the drawer" now, lol.
I guess it goes to show that you have to try things out for yourself, because what works for one person, may not work for you.
