The 581 & 681 are great shooting and mighty handsome, too!
Well used 581 that is a fun, accurate shooter
LNIB 681, this one is a bit unusual as it is one of about 465 made in the late 1980's for the ConRail PD and chambered in 38 Special.
While I do love the L frames, there is no shortage of interesting fixed sight N and K frames too if you want to play with something a bit larger or smaller
Model 58 (L) and 10-8 (R).
