This may be blasphemy, but I recently sold my (pre-lock) 586 L-Comp and bought a 4" 686-5 (also pre-lock) to replace it. I found the 3" L-frame too big to comfortably conceal and prefer the balance of the 4" at the range. As an added bonus, I could buy two 4" 686's for what I sold the L-Comp for.
Not blasphemy IMHO... I'm with you a 3" L frame is too big to CC IWB...
I had a 3" 586.... traded it for a PC Shorty-9 IIRC.......(looking back should have kept it as a safe queen LOL).
IWB CC I'll stick with 3" k-frames.................
