I have been having some success with a S&W model 10 in 38 special. I find the medium K-frame more comfortable to shoot than the N-frames in 45 and 10mm/40. I use the Safariland comp 3 speedloaders with a Blade-Tech holder and load almost as fast as the moon clips. I make up the difference in speed because I can shoot the smaller gun faster and more accurate. I had a chance to shoot one of the Ruger 9mm revolvers and I like my model 10 better.
I will be at the Ohio State. I haven't decided whether to shoot my revolver or my Glock.
