|I bought this for a gen 4 model 22. What I received was a set of grip force adapters for all generation glocks ( 1 - 4 ). One has the serrations, the other is smooth. The one with the serrations, or ribs, I installed on the gen 4. The smooth one I installed on a gen 3 model 17. Installation was fairly easy on both pistols.
In my opinion, the adapters improved the grip on both pistols, And it looks pretty good too. I am very happy to get two for the price of one! Overall, this is a good product, and a good value.
Haven't been to the range yet, but confidence is high. I like them both, but I am leaning toward the smooth one as a little more comfortable. Time will tell. Either way you go, I think you will be happy with this purchase.|
