I have three 3” J frames, two steel and one aluminum framed.
I have eight 3” K frames.
I also have a 3” King Cobra.
At 28oz, the King Cobra is right in the middle weigh wise and about the middle size wise between the steel 3” J frames (my 3” M60 weighs 24oz) and K frames (about 32oz on average.) But much heavier than the aluminum 3” J frame. Can’t recall the 3” M37’s weight.
I think the King Cobra competes against both the steel 3” J and K frames (and cheaper than the current 3” K frames.)
A 3” J frame, or even K frame, fits in the pockets of my khakis or dress pants, but doesn’t work in my jeans.
In the end, though, if I’m carrying IWB, it’s a P365x, in pocket (very rarely) it’s a P365. Open carry, it’s depends on a bunch of factors, but a 386PD has been getting the nod a lot lately. Or the King Cobra.
