Which makes all the hand fitment discussion particularly freaky, as the K and L frames utilize the exact same size stocks.
As someone who shoots full underlugged 8 3/8" barreled revolvers both K and L frame (some with scopes) down to 2" snubbies whilst standing on my hind legs I've never gotten the "balance" thing, but that's a whole different subjective matter.
True, the K and L and, I understand. the X have the same
size for fitting stocks but it's the sizes and configuration
of the stocks that count, not just frame size. Some
find the Magna stocks just about right while others
require a Jordan sized stock.
As for balance, it is both physical and mental and the
right balance is when the firearm hits that sweet spot
of handling quickly and accurately. And yes, balance
can also change with age and physical strength.
To me balance is a 4-inch K-frame, it just sits
well in my hand, with correct stocks, and I'm
able to be adept with it and quick as well. I
could never say the same with an 8-inch revolver
even when I was young and much stronger.
