Not sure they will be much better. The body of the five star appears to be the outside diameter as the Comp I they both have to go around the outside of the rounds so they have to be close to the same OD. Comp I are really thin between the OD of the speed-loader and the round.According to five star, their speedloaders clear the grip. Can anyone confirm that?
I have enjoyed these. Get faster all the time with them. I like the way they carry.(I also prefer the factory grip)

I shudder to say this, but you can clearance the grips with a Dermel tool. I make my own grips, and it's easy to do.
