I carry a +P rated 38 Spcl S&W 649-2 (1 7/8" bbl ) with Speigel boot grips, or a 3" full-lug S&W model 60-4 38 Spcl with factory rubber combat grips. Great revolvers. These J-frames are more accurate than you think.
Load is a hard-cast SOLID-base 148 grain wadcutter over 3.5 grains Bullseye (Lee tumble lube DEWC or H&G #50 ).
Good article by Ed Harris about full-charge double-ended hard-cast wadcutters in the 38 special :
