Spike RD3-018 Red Dot Sight for Canik TP9 Elite SC, Canik Mete SFT, Sig Sauer 365XL, Ruger Max9, FNH Reflex MRD, Springfield Hellcat OSP/PRO – Sensor Activated/Automatic Brightness

Excellent.It fit perfectly on my Glock. I recommend it 102%.

The sight works great, instal was easy and simple

I bought this to put on a Canik TP9 SC Elite (subcompact), which is basically a range toy for me — not a carry gun. I didn’t want, or need, a sight that cost half (or more) the price of the gun. I’m an old guy with old eyes, so red dots (or lasers) are a big help to me. My review focuses on that installation, but some of the things I noted may apply to other applications. The sight seems well made. It comes with 4 each of several different sizes of mounting screws (and another allen wrench… I have a zillion already), one size (see later) being the one needed for the TP9. There’s also a rubber cover for the sight, and some sort of “dial-like thing” that I have no idea how to use (and it’s not needed). The paperwork that came with the sight was sort of crudely printed — a give-away, perhaps, that this sight isn’t on par with far more expensive ones, even sights made in and imported from you-know-where. The sight mounted easily, it was very easy to zero, and although I only put about 100 rounds of ammo through the gun after sighting-in the zero held. The sight co-witnessed with the factory iron sights on with no issues. There are 2 dots on the rear of the sight that you can supposedly use, with the gun’s front sight. if the battery dies and your iron sights are cowitnessed. However the ADE sight mounts so close to the rear sight on the TP9 that I couldn’t see the dots… but I could see, and line up, the gun’s front and rear sights. WHAT I KNEW BEFORE I MADE THE PURCHASE, BUT AM NOT THRILLED ABOUT: BATTERY and BATTERY CHANGE: You have to remove the sight (and probably have to re-zero) to change the battery. I posted a question about battery life on Amazon. One gentleman responded that the battery that came with the sight (a no-name battery that also came from you-know-where) died after about 2 months, but so far his replacement has been working for about a year. I suggest that before you install the sight on your gun go ahead and immediately toss the supplied battery and install a “good” brand name one; they’re not very expensive, and that’ll delay need to remove the sight and re-zero after you got the sight on. I suspect part of the battery issue (if that’s the right word) comes from the fact that THE DOT IS ALWAYS ON; not shake-and-wake, which I would have preferred. NO MANUAL BRIGHTNESS CONTROL: The intensity of the red dot changes in response to ambient light. It certainly does if you go from a totally dark room to bright sun, but in between the intensity changes with ambient lighting aren’t very obvious. When I was shooting at my indoor range, with a couple of not very intense bulbs overhead, the dot seemed way too bright (and big) to suit me. In fact it was so bright that the dot reflected off the lens, giving what I’ll call a “false dot” that’s not the one you want to aim with. That bright dot also appeared way too big; in really bright light the dot not only gets dimmer, but smaller. If you’re shooting at, say, 25 yards, I think the dot is too big. THE UNDERSIDE OF THE SIGHT ISN’T COVERED AT ALL: I initially installed the sight directly on the optic cut of the TP9, but now the holes where the screws for the optic cover plate originally were were open, which lets lube and powder residue (admittedly not a lot, but I only shot 100 rounds) get out of the slide and on to/into the sight. I didn’t think that was very good, so I reluctantly put on the spacer plate that came with the gun then installed the sight on that. That created, at least for me, another issue. The mounting screws supplied with the sight (for the TP9 SC that was M4-0.7 x 10) were long enough to secure the sight directly to the slide. With the gun’s spacer plate those screws seemed too short, and I worried that an accidental slip of the hand when racking the slide might break one or both mounting screws off and knock the sight off. (That happened to me with another sight and gun.) But the sight didn’t come with longer screws. Local Lowes and Home Depot didn’t have longer ones, but an ACE Hardware surprisingly did. For the TP9 SC I recommend M4-0.7 x 14 or, better, M4-0.7 x 16. In SUMMARY: For a “range toy” this ADE sight is “OK,” and so far a good deal for the price. I’m comfortable with the purchase. Because of uncertainty about how long a batter will last I’m hesitant recommending using it on a gun being carried for self-defense unless you’re pretty fastidious about changing the battery and have cowitnessed iron sights, but that’s up to you of course.

Super easy to install. Fits perfectly on my p365xl. Easy to sight in. All tools provided. Comes with a cover to keep it clean. Great price. Will see how long the battery lasts.

Was extremely easy to attach works great. For th price I would recommend

I hate the fact that it stays on draining the battery

Didnt fit the base that was specified and hate the fact that it won't turn off. Battery only lasted a few days..

Item arrived quickly. It was a gift so I hope it works well
