Jim in Idaho,
It's not about tougher, it's smarter.
After trying full power 357 loads in my SP-101 the factory grips went away and I switched to some nice wood Hogues.

My standard 357 loads are 11.0 grains AA9 with 158gr Keith style w/ GC or 158 XTP's and are not too zippy. I also set up a 158 gr. in 38 Special + P brass (think 38/44).

You are right about 158's hitting the same POI out of the 3 inch, kind of a nice thing.

Here as of late my new woods bumming gun is a S&W M696 3" with 240gr. Keith style with 7.0gr. of Unique.
