When the shooting sport IDPA was creating their competitive divisions, they initially had two for revolver, because it was believed that moonclip reloading offered enough of an advantage that speedloaders would not be competitive.

Over time, sophisticated speedloaders were developed that, for competition, made reloading speeds about equal, but I suspect a five-shot J-frame is going to be limited to the HKS-style "slow loaders", and moons will be quicker under ideal conditions, and much quicker and more certain under dire conditions.

I'vs shot a few years' worth of IDPA competition with moonclips, and the only bent clip I've experienced was one that was stepped on; they are pretty strong and durable.

I'd be reluctant to cut on an exotic titanium cylinder; would a used J frame, already cut for clips, be much more expensive than modding your existing gun?
