I've seen a field grade .454 used, that had the rubber pachmayr grips on it. The grips had two splits in it, one on each side running down the backstrap. They were about 1/4 inch long each. Apparently, even the pachmayrs, which wrap around the back, will begin to split under recoil. Has anyone here shot one of these with pachmayrs versus one with Micarta or wood grips? Some folks like the idea of rubber grips, but I was wondering if it wouldn't be better to go with Micarta, and just let the revolver roll back under the recoil. It seems like when you first start out shooting the handcannons, the recoil can be a little harsh, until you learn exactly how to grip and go with the gun under firing.
