Yeah, what I want out of our 637s is small enough to fit in a pocket, and light enough to carry without being a nuisance. They fill that purpose. As an aside, my brother recently used his to scare off a home invader who woke him up in his bed in the wee hours by beating him in the face with a metal bar. Three shots, and my brother says he didn't notice the recoil at all (he deliberately missed all three shots - didn't want to kill anyone). He has the titanium cylinder as well. Lightens the pistol up by a bit over two ounces.

Another aside - I admit a sentimental fondness for the Tom Threepersons open toe holsters.
