Well, my L-frame experience is limited to an old M581. I've owned several K-frames over the years, but (foolishly) rid myself of all but 2; a 1970s vintage M19 and a 1950s vintage M&P (2 " barrel).
I carried the M19 (4" blued steel) on duty as a cop in the late 70s & early 80s. Fitted with genstag stocks and a Tyler T-Grip Adapter, using .38 Special "FBI loads" (+P 158 grain soft lead SWC HPs, for you youngsters out there), I felt pretty well armed. I was a member of my department's 4-man PPC team, using a modified M10 (6" Douglas tube and Bo Mar sight rib), and firing thousands of practice rounds annually through another K-frame led me to be pretty confident of my ability with my service arm, under stress.
The ability to use magnums, if necessary, was a plus, but I always thought the old FBI round was pretty effective "up close & personal."
Maybe the L-frame will do anything the K-frame would do, but the K-frame did all I ever asked of it.
