Excellent upgrade for stacatto cs

Review by DAN L. on 27 Apr 2025 review stating Excellent upgrade for stacatto cs
I bought this for my stacatto cs because the little tab at the end of the stacatto captured guide rod assembly is not round and when reassembling the pistol the part might turn just enough to keep it from going into battery. I have the dpm systems in most of my other guns no complaints. I like that they include additional springs for tunability.
