My all day every day carry gun for the better part of a decade after I retired. Had three, still have two. Shot around 9,000 rnds thru them (mostly 240 - 260 at 1,100 fps). If shot frequently with high intensity loads, they will require more repair/maintenance than their steel counter parts. Don't know repair/maint frequency with .44 specials, but suspect it not to be an issue. Still carry mine as backup when bow hunting elk here in Montana.
The Buff Bore low recoil ammo chronos 1,264 fps out of the 4" M69 (per BB site) - same as I got 5 long paces from the muzzle with factory Remington 240 JSPs (vs BB 255gr). These are full power .44 mag loads.
Don't shoot it with the grips that come with the gun -- buy some Hogue or Pachmayr rubber grips that cover the backstrap.
Here's one of mine
