I use the VZ diamondbacks on my 1911's and Shadow. These have a great rough texture. They can be sanded smoother for soft hands, but don't take long to get used to. Then anything smoother feels almost slick.

The new 17 gen 4 that I just did the trigger on had the same return problem. I had put the stock return spring back in it to correct it. I had no idea that it was related to the firing pin spring. I had installed a 4#.
