Had 3 guns -- still have two. 9,000 rnds thru the three. One had 900, the others shot the rest. If you frequently use hi intensity loads, the guns will require repair/maint quite a bit more often than steel counter parts. Don't know about longevity with .44 special ammo.

That is amazing. I always considered the 329 an emergency use gun with magnum loads. Like the old days when cops practiced with 38 wadcutters, then loaded up with full power 357 mag rounds for duty carry.
I am going to assume you you like your model 69s more than the 329s. True, or no?
