I have two of these. The first one I bought has the Apollo 6.5 Creedmoor reticle in it. THAT scope has full reticle illumination. It's bright and crisp. No complaints. The glass and everything are just fine as to be expected from Primary Arms scopes.
Being as I liked that one so much I decided to buy another in the .308/6.5GRN Apollo reticle. Same reticle, different illumination. With the .308 version, ONLY THE CHEVRON in the middle is illuminated. I sent it back to Primary Arms thinking it was defective, and ultimately sent it back for a refund. This may be fine if that is what you like and/or are looking for, but that is not what I thought I was ordering and I will go another route. Again, the scope itself and optics looked just fine. No complaints on that.
If this difference in illumination of the same reticle between calibers was made readily apparent in the advertising, I could have made a more informed buying decision and saved a lot of hassle. Hence the reason I am laying this out in the review.

I bought the Shockwave model because I have a 590M #50206 that uses the 6-3/4" slide. (You will be needing a tube nut wrench as the nut in recessed quite a ways into this. I used the Leapers TL-SHWR01 and it worked fine.)
While it DID fit on the slide tube nicely, upon putting the barrel back in I found that it bound quite heavily against the bottom of the barrel. To the point of bending the slide tube out!
I solved this problem by removing a fair amount of material from the two upper edges and tops of the inner ridges that ride against the barrel with a half-sheet electric sander and some 36 grit. Cleaned up with a file.
I used a 30mm scope lapping bar to check my progress as it happened to be the proper size for barrel clearance and was the same radius as the factory forend top cut.
Overall though I am quite happy with the product so far. At about $130 and fitting the shorter 6-3/4" slide tube you would be money ahead to just do some fitment trimming.
The light is bright and works as it should. Tap for on. Tap for off. Hold for momentary and then it goes off on release.
