A lot of the improvements are not in the products themselves, but in the way they are manufactured.
, too. They've played (and still
play) a key role in revolver evolution by helping the platform realize it's potential.
Speedloaders, full moon clips, kydex holsters, increased capacity, improvements in sights, optics, understanding how to really tune the actions and/or accurize the gun itself, improvements in bullet design are all things that guys like Ed McGivern and Jelly Bryce never imagined, and offer modern wheelgunners the opportunity to do things even they didn't do. Sounds like evolution to me.
