Find one of the seven shot Models 520 or 620. I have a 19, 27 (x2), a 66, a 520, and a 620. The 620 is my favorite .357 handgun as it fits my hand better than the N-frames and is smoother than the K-frames. Sort of like the Mama Bear's bed of S&W .357 Mag revolvers, not too big/heavy and not too small/light, just right, at least for me.
I bought a like-new 620 for $350 about twenty years ago. Some have fussed about the two-piece barrel (same as the .500!), but as you say, I find it to be an excellent balance of size, power, and capacity. The half-lug barrel is an excellent feature. They still make other 7-shot L-frames, but I didn’t see any with the half-lug. Right now I have a set of the polymer Jordan grips on it, with a bit of grip tape here and there. Also have a Milt Sparks black horsehide IWB holster and a Simply Rugged pancake. Carries pretty well in a good holster.
