Some random thoughts on the 329.
I carried a 329 all day everyday for five or six years here in MT
I’ve shot close to 9,000 rounds thru three 329s mostly 240/250 gr Lead SWCs over a charge of 2400 at between 1,100 and 1,200 fps. I never found cleaning to be much of a problem. Had the guns back to S&W 6 or 8 different times. Had frames replaced, hard extraction fixed, carry up (timiing) fixed, firing pin replaced, blast shield replaced and a couple of things I've probably forgotten. One of my guns in the pict posted above by 243winxt -- that's under the blast shield, which had eroded in two pieces and fell off.
S&W repaired/replaced as required at no charge to me and paid shipping both ways every time. These guns are a trade off and I knew/accepted it.
With that said, I suspect most 329s don't (will never) get that kind of use with heavy ammo. I have never shot a meaningful number of .44 special level loads to know for certain that the above problems won't occur with lighter loads. My guess is that they will last a long time without any problems shooting .44 special/equiv. ammo.
The light weight scandium Magnum revolvers seem to have a greater tendency for the "lock" to engage under recoil.
Also, you need to test your ammo to make sure that bullets stay put under recoil (they tend to be bullet pullers which can tie up the gun).
By its very nature (express rear/fiber optic front; short sight radius, and light weight) the 329 difficult to shoot well. Add in the harsh/fast recoil of full .44 magnum loads, and the gun is a pretty short range proposition for most. Obviously, there will be exceptions to this, but for the most part the typical shooter will find the 329 difficult and probably even painful to shoot with .44 magnum level ammo. Others have said, if you want a dedicated .44 magnum for continuous use, get a heavier gun. If you already have a full size/weight .44 mag, then you should give the 329 a try. Start with .44 special equiv loads and work up to your comfort level. There aren’t many handgun chores that can’t be handled with 240/250grs at 900 to 1,000 fps (which can still be a handful in the 26 oz 329).
I still have two 329s and while I carry them more than occasionally (loaded with full house .44 Mags), I don’t shoot them much anymore. I’ve pretty much replaced them with the M69 – I do carry the 329 exclusively when bow hunting elk – this is where the light weight is a noticeable advantage. All my round butt S&W’s are equipped with the Hogue 500 grips, so it’s an easy to transition between them. Just a note – I shoot enough lower end .44 mags thru the M69 so that, while the recoil of the 329 is noticeably faster, it is still controllable for me.
