I bought this PSA Dagger complete upper (slide) and Holosun sight a few months ago. It was a great deal and the quality is great. Slipped right on my Gen 3 Glock 19 frame. I have no complaints about the sight or the slide. It gets flying colors for my reviews.
However, the sighting system troubles me, as it does a lot of experienced shooters. Learning to shoot a pistol red dot is a new skillset and it's not coming easily. I'm sure it will with practice, but I need to shoot a lot. That means 9mm will be expensive. For the cost of 1000 rounds of 9mm I can shoot 5000 of .22. So I'm pretty sure I'll be buying a Sig P320 with a Romeo Zero.
As for this assembly, I may dispose of it or keep it and see. I don't know yet. I certainly would not have bought it except to review (probably the same with the Sig with the Romeo Zero).
