Well, I was thinking of the weight factor only which is what my entire post addressed, but I am appreciative of your post.
Though grips are a non-issue since they can be changed in under five minutes and there are scores of options, a lighter trigger pull would be a real benefit. Durable finishes are nice too.
Regarding "energy-absorbing" and "felt recoil reducing" firearms materials and designs, it has been my experience that they are largely marketing BS. The only guaranteed solution to reducing felt recoil by any meaningful amount is via increased weight. For example, the felt recoil experienced when shooting full power 10mm loads from my big, heavy, all-steel Smith & Wesson Model 1026 is significantly less than that experienced when shooting the same ammo from the lighter Glock 20 with its "recoil-absorbing" polymer frame. I could give other examples, but I think you understand what I'm saying.
