I have an old 19 that was re-barreled by smith, a 686+ 3, 686 + 5, a 627 PC, and DW 715. Out of them all, i prefer the 715 and 19. The 627 is a close 2nd to those two. The 686+'s are not bad, just not quite the equal of the others.

So as to why I like the DW 715 and the 19. Their DA triggers are smooth, consistent and a middle of the ground 8lbs or so. I am more accurate with the DW than the 19, but not much. The 627, hands down, has the best balance in rapid fire.
If i were to have any gun on me when around the property though, it is the 686 + 5". It is the one that holster is designed for. It shoots well, carries easily, and has a better in the hand feel than the shorter 3".
