Been using this combo for 30 years, but recently trying a Ruger LCR. The hammer spur on the Colt has left many a scratch on my hand and arm from everyday carry. Heresy, I know.
I was primarily carrying a Taurus 605, but, well, six shots over five. Fit the couple of holsters I had for the Taurus and HKS K-frame speedloaders seem to function just fine (of which I have several).
Only negative is that Crimson Trace doesn't make grips for it. But did I mention six rounds?
