Re: the S&W model 36- that hammer spur might make drawing from a pocket problematic ......
I had a Ruger sp101 (3") in .357 ..... while I really like the gun, I just could not find any way to carry the thing IWB in any manner that could be construed as comfortable ..... I found that revolvers are ....well, round ...... and don't sit under your belt very well. A 5" steel framed 1911 rode better, with less printing than the Ruger did, even though the 1911 was a bigger, heavier gun- Old Slabsides was flatter. JME, YMMV.
