I had a Pachmayr Diamond pro fitted to a 5" 460V at one point.
It lasted about 100 shots before the rubber started to tear around the backstrap, it is made of a very soft material. Taking it off again was also somewhat of a challenge, as the small diameter retaining screw had been severely bent from the recoil.
But that was in a relatively short barrel non-compensated X-frame with heavy loads, it will probably have better longevity in a long barrel .44.

My biggest issue with these grips is that they don't fill the space between trigger guard and grip frame as much as Hogue's or the Pachmayr Grippers do, so that the middle finger will ride higher up behind the trigger guard, leading to the trigger guard beating my middle finger every time the gun was fired.
