S&W K frame snubs.
I'm very partial to my 66's, one 3', the other is a 2.5", both are extremely accurate with anything I run through them. And surprisingly to me, full house jacketed 296 loads are just as accurate, as +P 38's.
I also have a M10-5 with a cut down barrel, 3', and that gun is all kinds of fun and accurate to shoot.
Everything from 110 gr. JHP's up to 158's produce excellent accuracy at 15-20 yards. The only down side to shooting full house 357's is the excessive recoil and muzzle blast, and it's quite excessive. Those 296 loads could easily start the BarBQ up, they are flame thrower's, but really awesome to shoot at night time.
For a more enjoyable shooting experience though, +P 38's are quite comfortable to shoot through the snubs.
And though a 4" isn't a snub really, shooting the 4" Taurus 608 (8 round cylinder) with full house .357's is pretty comfortable to shoot. The comped barrel really makes a difference, as does the added weight of the hefty frame and larger grips.
