I've had three over the years. Still have two. Mine are equipped with the Hogue 500 S&W tamer grips. Shot around 9,000 rnds thru them (started keeping count after first negative event). Loads were 240gr to 265gr Jacketed/Cast at a chronoed 1,150 to 1,250 fps (Rem 240gr JFP factory chronoed 1,250 fps). My primary carry gun (all day every day) for the better part of a decade. Still carry one when bow hunting elk in high country. Always considered the 329 to be a primary defensive gun. For this reason, always liked the "V" notch rear and fiber optic front.
With that said, these are very specialized pieces of equipment. If shot a lot with loads equaling the above, they will require frequent trips back to the mother ship. If primary use is .44 special equiv and occasional .44 mag, then maint/repair frequency probably a non issue.
"the lock" is a potential problem. Also, carry ammo needs to be vetted for crimp jump -- these are extreme bullet pullers.
For me, the key to shooting these comfortably is:
1. Use the X Frame 500 grips -- not those provide by the factory.
2. Grip the gun a bit lower than you normally would (place you hand on the grip lower).
3. Don't mussel up on the grip -- not loose, but no gorilla grip.
I'm a fan, but don't try to make it more than it was designed to be -- short range, up close and personal, light weight carry gun. Have run 300gr+ over max charge(s) of 110/295 -- not for continued use, but doable.
Continued shooting of hi intensity loads will wear on the anatomy, so proceed with caution.
Load it to the threat level in your area and enjoy. Remember, under stress, recoil won't be a factor.
FWIW,
