I've got them on my Walther PPS M2s and P99Cs (I've got two of each). I tried the Pro version on one of each and will switch the others to Pro as well.
I have Talon grips on three Glock handguns; 19, 21 and 42. They were easy to install. I don't have any S&W semi-auto pistols. Here's a set on a Glock 21 .45 ACP:
I did have the granulate texture Talon grips on my original Shield and liked it. I haven't felt the need to do so on my M&P 2.0s or my Shield Plus since they've got more aggressive grip texture from the factory.
I've found that a small strip or two of the 3M tread tape made for something like ladder rungs is an excellent enhancement without all the real estate covered by Talon grips. It available on Amazon, a roll will last a lifetime, stays put but comes off cleanly.
