They are. The lockwork and the smooth trigger has a lot to do with it, but I also think the size of the frame is a big reason. Most folks have average sized hands and the K frame is just the perfect average size. Ed McGivern had small hands with stubby fingers and the K frame fit him perfectly. On the other hand Jerry Miculek is a bigger man with considerably larger hands and he likes to use the N frame for his work. But most of us aren't his size. I'm 5'6" with average sized hands. I get it.

Funny you should say that, I'm roughly the same size and about my favorite wheel gun is my Police Positive Special because it just fits my hand perfectly.

Needs a 21" barrel. Why? Just because, of course. :D

When I was younger I didn't like the K frame because it wasn't big enough. If it wasn't a Dirty Harry sized revolver I considered it wimpy. But then I considered myself to be 6'00" tall despite what the doctor would tell me during my various Army physicals. I got older. Realized I wasn't a basketball player and realized I liked a revolver that actually fit in my hands.
