Charley,
I wanted to do a GP100, or an older Speed Six for IDPA for awhile. I realy like the 3" GP100 with the lighter barrel, it reminds me of the older guns without the lugged barrels. I guess one of my problems with the whole Ruger revolver series is choices. Everytime I think about it, I run into some S&W revolver, I get ideas about. The selection on the Smith side is so wide range, that I just forget about the Ruger. I wish Ruger would come out with a few more unique offerings based on the current lines.
I'd be curious why the change from the 3" to the 4" ?? ALSO, tell me more about the Meprolight night sights. Both front sight and rear sight blade ? I've had some thoughts on Ashley Dot set or some others for my Model 24 44 special I'm starting to use in IDPA.
