I treat my 69 as a 44 Special that can handle stout loads and an occasional cylinder of magnums. One or two cylinders of full power magnums is enough for me in any range session and my gun has the 500 grips that do a better job of cushioning the recoil.
Even if you don't reload there are options, at least there were before the current ammo shortage started. Try some cowboy loads, 44 Specials or weak 44 magnum loads before you give up on your gun. My favorite load is a 240 grain FMJ from Georgia Arms listed at 1000 fps (
.44 Rem Mag 240gr Full Metal Jacket NEW - Georgia Arms). Strong enough to be interesting but not so punishing I want to quit after a cylinder. Its currently out of stock and priced twice as high as it was two years ago but hopefully this ammo shortage will eventually end like previous ones did.
Also, try replacing the grips. The hard rubber ones that come with the gun don't handle recoil particularly well.
