remember you will need a 4" barrel. I have a 627 N frame(moon clips} A 646 L frame(.40 S&W w/moonclips) a Mod 19 K frame (speedloaders)
I have shot all of the above in IDPA includig a Kimber Custom Stainless and a PRO Elite.
I think the moon clips are a pain in the ass, loading and unloading. Also on the 627(8shot) hard at times to get in cylinder. Time wise I have the best luck with Speedloaders so I use my Mod 19. Ther is just something about pulling out a nickled 19. Kinda like Cowboy action shooting.
The place I shoot at , the courses of fire, are revolver friendly, hence 6 shot stages.
Although I do shoot my .45's my Mod 19 is my favorite and I am most accurate with it..................................
One other thing I shoot against myself. I don't try to "win "
So I don't always "follow' the sequence of shooting ( why should I shoot 1 to the body when I already put my first shot in the head?}
I personaly think some of the senarios and rules in IDPA are CA-CA.. BUT IT IS ALOT OF FUN.....OTTO
