Can you tell a difference in Gen 3 vs. Gen 4 in felt recoil (40 cal models)? Assuming that I don't mind the Gen 3 standard grip (size and texture) is it worth waiting for a Gen 4 G23 in your opinion? My only beef with Gen 3 is I find it slightly slippery in terms of texture and I'm not a fan of RFT. I guess in my mind I'm holding out for the upgraded recoil spring, specifically for .40 models. Back straps don't really appeal to me much. The new RFT grip interests me, but worth the wait? I can't find any Gen 4's in the Cleveland area to test the new grip out.
