I just acquired one and did a 5 min install on a 39. Pretty easy, drift old sight out with supplied drift and hammer. Install new one, center it, and secure with allen screw.

Adjust windage and elevation to 21 feet and do final adjust at range. I like it so far, brighter than guide rod laser and equal to CT without making grip fatter. Easy press button activation.

I'll give a report after range session, encouraged so far and have seen mixed reviews on the product. Oh, 95 bucks on Ebay, two day delivery.

I think you made a good choice. I have had one on my 19 for a couple of years now and it keeps growing on me. It's accurate, secure, dependable and there is no need for a special holster.
I have tagged this thread and will be interested to see how you like it.

I shot the other day and, first shot at 7 yards was precisely cutting x ring on head shot. I started to quit. I fired 15 more, all right on and I never looked at the sights, just the dot.

So far, so good.

Thanks for the update. Sounds like it is working and you are happy with it. I love a happy ending.
