Picked up a NIB 632 ProPort .327 Fed Mag yesterday. Had a good supply of .32 H&R Mag ammo on hand. What a fun little gun. Can't imagine the muzzle blast w/ the hot .327, those H&Rs would really get your attention.
You just bought what IMO is the neatest J frame S&W has built in a long time. The 327 mag loads do bark and you'll know you're shooting a true magnum. This is one very versatile revolver and a joy to shoot with any load. I hope you enjoy yours as much as I do mine.
I picked up a 432 a week or so ago (as a companion for my 16-4) but haven't got to shoot it yet. I really like the 32 H&R and bet the 327 mag is a blast! (no pun intended)
