Hi...
I shoot most firearms pretty well. I should because I shot handguns competitively for several years back in the 1980s.
I own and shoot all types of handguns, but I have a few that are just tough to shoot accurately.
One is a Cimarron Mason-Richards Open-top conversion in .38Special. Beautiful revolver...very small practically non-existent sights. Great fun to shoot, just hard to hit anything with.
Second is my WWII bring back German Luger. Once again, very small sights. Lots of stuff going on with that toggle-action. Fun to shoot an historical firearm.
And, third, my nickel-plated Webley top-break that was re-chambered by someone somewhere to .45Colt. My gunsmith says it is safe to shoot with factory level loads, but nobody can hit any thing with it. It will keyhole cast lead bullets at anything much past 7 yards.
The barrel is marked .476, so those .45 lead bullets are just skidding down the barrel.
Nice old revolver...everybody wants to shoot it when I take it to the range, but no one can hit a paper bag with it from inside the bag.
