I do things a bit differently since I am a collector and a shooter. My "shooters" have grips on them that I prefer and feel good to me and allow me to handle my revolers the best way for me. (See Contenders post above). They may be Hogue finger grip, Ruger OEM, or something else. Back in the day when I competed, I built a copmetition revolver from a GP100 and the grips that worked best for me in competition were the black rubber (composite?) Hogue finger groove monogrip. Fit my had like a glove and as such at one time I was ranked number 4 in the Governors 20 ranking in Delaware.
Now, in my collections (The Six Series DAs, GP100s, Redhawks and the other Ruger DAs, the guns stay completely stock, they way they came from the factory. That allowes the people who come to the gun shows where ROCS is invited to show their Rugers to see how they came from the factory and ask any questions about them. We actually get a lot of questions from people who, believe it or not, don't know that much about Rugers products and they want to know the who, what, where, when, how about our favorite firearms. I can then point out that this is how it came from the factory and then show them pictures of how people might "customize" their handguns (grips, sights, etc.) to make them shoot more accurately for them.
