I have two of them, with laser grips.
They are so light I can carry one even in shorts.
I have 357 magnum power if I need it. I carry in the country and may want to pop a deer as well as two-legged varmits.
I can always carry 38 ammo but have found I can tolerate two cylinder loads of magnum without much ill effect.
I have full-size steel revolvers for range use.
With a 357 you have the option of loading down.
With a scandium gun you forget you are carrying it.
If your gun is so heavy you leave it at home it will do you no good.
Carry a lot, shoot a little.
