This is the best I can do to help. I don't care for L frames, I have a Python that is the same size that I like better. Here is a photo of J/K/Python/n.
One thing to remember is the K frame is a 38 that can fire 357 ammo but a steady diet of the magnum loads will damage it. N frames are great shooters but get heavy for carrying. So if you are planning on shooting a lot of 357 loads (especially the 125gr ones) look at a L or N frame gun.
I will be using my N frame to learn to reload 375 loads, I figure if I damage that gun I have really messed up.
L carry my K because they have the right balance for me.
