I have been fortunate to be able to shoot most everything well, from little.22 revolvers up to .500 Magnums. However, I also discovered that if I shot something extensively, there was a noticeable improvement. The difference wasn't like night and day but it could be the difference between match winner and 1st place. Most bullseye shooters follow the philosophy that you'll do better with like feeling pistols. I originally thought that I would shoot a model 41 for Rimfire, a model 52 for center fire and a 1911 for .45, in 2700 matches. I discovered that my scores improved when I used a High Standard Victor and the 1911 in both center fire and .45 matches because they felt similar, the same grip angle. I do really enjoy shooting a wide variety of firearms, even though I don't shoot them to the same level of precision, it's just more fun.
