I used to carry the 3" version,and I love the pistol, but it was still a little heavier and bulkier than I'd like. I don't carry everyday/everywhere, so I like to pocket carry, but the SP101 pretty much needs a belt holster, which limited the shirts I could wear. Kind of a headache, all around.
I ended up stumbling into a great deal on a S&W 642, now carried in a pocket holster ( as per Georgia law) and I'm happy. I can carry it wearing any old t-shirt, and a pair of elastic-banded gym shorts if I want,with no issues.
