I enjoy seeing nice grips anytime. However I am sure no one will even complement me on the looks of the grips on my two carry revolvers.
Nearly 70 years ago an older Cowboy gave me some advice that I have used since then. As a teenager then, I owned and carried a Colt .44-40 single action revolver as a working cowboy. From time to time the other men on the ranch watched me shoot that Colt at various targets, rabbits, birds, coyotes, just about anything a kid wants to shoot. I thought that I "was pretty good", shooting that Colt, almost always hitting what I aimed at.
One day one of the older men stopped me and said, "Kid you need to learn to really know how to shoot and you need to get a gun that fits you. You take too much time aiming". He showed me his revolver and showed me the grips that he had modified to fit him. He then drew his revolver, without aiming or even looking at the revolver he proceeded to fire five shots at knot on a fence post. The bullet holes on the post could all have been covered by a playing card.
He then asked me to point my finger at the knot on the post without looking at my finger, hold my finger in place and then look to see where it was pointed. After I did this a few times, he then said "If your grips on your gun fit, the gun will point the same place your finger points every time you draw and shoot. And when you point your finger, or your gun, do not look at the whole target. Point your finger, or your gun at one specific spot, such as a single button on a shirt, not the shirt, the eye of a rabbit, not the whole rabbit, the eye on the head of a flying bird, not the whole bird, etc. Look at the spot where you want that bullet to actually go".
In the evenings in the Bunkhouse for a while the old cowboy helped my make a new set of grips for my Colt from a chunk of hard wood. By trial and error we got those grips so that I too was able to make a smooth draw from my holster, looking directly and specifically at a point on any target, without having the gun even in my vision, and hit the target without delay and without aiming the sights.
Years later when I got my Ruger Blackhawk and the S&W .44 revolvers , I ordered custom grips made for each using the measurement of my hand for the grips maker. When I got the new custom grips I replaced the factory grips on both guns and using Emory Cloth and a scraper, I made final adjustments to the grips by trial and error until both guns will fire and hit a target without my even seeing the gun in my hand. Those are the guns I still carry and use every day today.
A number of years later, in Rock Springs, Wyoming, I had an opportunity to meet Border Patrol Inspector Bill Jordan who gave me his book, "No Second Place Winner". We discussed the grips on his and my revolvers. He confirmed that he also uses custom fitted grips for the same reason and the chapter on GRIPS in his book confirms both his and my experience.
