I can learn to shoot any decent gun well enough, and even some crappy guns. I can shoot a Jennings J-22 accurately enough to get most of my shots in the black at 25 feet. I can shoot a Diamondback DB9 accurately, while encased inside of a wallet holster at 25 feet. I could shoot an INA knock-off of a Chiefs Special accurately out to 25 feet. I could shoot an AMT 45 Back-up accurately out to about 30 feet.
Those are all pocket-guns, not meant for long distance shooting.
If you can't pick up just about any gun and figure out how to shoot it accurately and consistently after putting 100 rounds through it, you haven't had to shoot many different kinds of guns.
I have only fired one gun that I really hated. It was a really old S&W 357, I believe it was a Model 28. It didn't fit my hand and the combination of the heavy trigger pull, recoil and grip hurt my hand. Well, the AMT 45 Backup hurt my hand too, but after 150 rounds.
