Is It Just What You Get Used To?
Measuring the distance from the center of the trigger to the top of the sights of the 1911 finds it's 2 1/4". On the single action revolver the sights are 3" above the trigger. I carried and shot the 1911 for years as a peace officer. Retired I prefer the single action revolver.
Comparing the different guns, the rear sight on the single action revolver is directly over the trigger however the rear sight on the 1911 is over 2" behind the trigger. The front sight is 4 1/2" in front of the trigger of the 5" 1911, on a 4 3/4" single action Colt's the front sight is over 6" in front of the trigger.
Not only are the grips not similar in any way, but the 1911 grip rests between the web the thumb and forefinger while the single action grip places an arched backstrap in the palm.
So all these differences and I question if we chose a gun because of what we are used to or are our hands that much different that 2 totally different guns suit some humans better than others because we are that different.
I recently we to a gunshow and found what I was looking for, a 6" L frame blued without the lock in the sideplate. The grips looked great but it felt so foreign in my hand I didn't think I could ever abide with this gun so I didn't buy it. I carried a 6" .357 DA for a decade before the massive transition to bottom feeders. I competed and shot that DA all the time, that was then, now it's like a foreign object to me.
With polymer the gun manufacturers can make any design and they are all trying to sell a better mousetrap but so far I haven't found one I want to buy.
