I'm new to using moonclips, been to the range twice with my M610, and haven't fully appreciated and understood the utility. BUT I don't shoot competitively like
mcb. Even at the range shooting bench, with both hands and no timers going off I can't drop my moonclipped rounds in the chamber as fast as he can!
I think I'm more of a shooter like
35 Whelen...more deliberate. I like to pause, review my last string and plan/correct for my next string, For unclipped 10mm, it's not too bad picking out the cases, but I have to use the moonclips for 40S&W rounds. Moonclips are definitely handy, but I have to keep a cloth at the ready now because all that demooning gets my fingers pretty dirty (no biggie, but still, an extra thing to remember). I see the pros/cons of the moonclips, but haven't fully decided my preference. Gotta say, if Smith made a 9mm in the N-frame, I'd be hard-pressed to not jump all over it.
