Mine is the alloy frame. I don't have any concerns with using the 22WMR cylinder, just don't have a need for more power, at a higher cost. In fact, some of the most accurate ammo I've found for it is the much malined Remington Golden Bullet bulk from Wallyworld. Pretty much does what I want it to out to 25 yards or so.
