Otter Shake Awake 3 MOA Micro Red Dot Sight, fit RMS-c/507K Footprint Pistol, 1x21mm Mini Open Reflex Optics Compact Scope, Shockproof, Lightweight

I purchased the Otter red dot last August, and I haven't regretted the choice at all.Installation on my pistol was simple, and all needed screws were provided in the box by Zulisy. The sight has been rock steady and held zero through several thousand rounds of practice firing. I like the battery access on the side, so I don't need to unmount the sight to change a battery. (Not that I'll need to do that for a few more years!)Mounted on my Hellcat Pro, the sight is set low enough that I can still use the factory iron sights, and is only a fraction of an inch wider than the slide. The sight fits the size of the pistol well, and has not affected handling at all. While there is some wear on the sight, overall the finish has held up as well as the finish on the pistol itself.The controls are easy to use, the sight window is generously sized, and the red dot is bright and clear. I set the brightness at 5 or 6, and have no problem seeing the dot in bright daylight, without being overwhelmed in a dark room. The shake awake feature works consistently, and the sight is always ready to use by the time I raise my pistol to take aim.The only quibble I have encountered so far is losing the battery tray retention screw, which apparently worked its way loose after two months of shooting and daily carry. Fortunately, Zulisy included a couple of spare screws in the box. I added a dab of loctite to the new screw before installing it, and haven't had any trouble since. The screw has not loosened at all in the last 4 months.Overall, the Zulisy Otter provides premium performance with a budget-friendly price.

Really like the size and quality has been very good so far. I've put about 1000 rounds through the firearm with this optic on it. Perfect operation so far. Shuts off after 4 minutes, timed repeatedly. Only thing zulisy could do is make an enclosed version so crud doesn't build up in the view. A few thousand more rounds should be forth coming. Really nice sight! Mounted perfectly to my Tisas 1911 b9ds carry.

Iam a full time gunsmith and firearms instructor at a premier indoor shooting range. I install optics on firearms daily. Additionally I have over a dozen different handguns that I not only carry but shoot regularly. I have optics that range in price from 900.00 to 150.00 on these guns and I love finding small companies like this who offer a quality product that is also affordable and durable for my clients.I have purchased 2 otters 1 red and 1 green recently and they are on 2 different edc’s These optics are amazing and iam hard on them. If your looking for a solid optic that won’t break the bank buy these, you won’t be disappointed!

The Otter sight is made of aluminum, though the photos suggest otherwise. Like the side (rather than bottom) mount for the battery. Like the manual on off rather than relying fully on the shake awake, etc. Comes with a wide screw assortment so it's likely one will work for your pistol. Have not zeroed it yet, so I've held off one star. If you've never zeroed a red dot, do read the instructions before you attempt it. The adjustment is NOT intuitive and the positioning of the red dot in glass is deceptive relative to the point of impact.

Very nice little sight, the auto turn on I like, it’s not to small and not to big, dot dials down nice accordingly to a fine point. I’d add a picture but I don’t think I’m aloud to do so, but take my word for it it looks like it belongs!!

So far so good. Performance on par with the cost. Shake awake works well and was easy to mount no issues

Completely died after a year and a half. Worked well prior to that. I thought it was the battery, but it's not. Thought it might be the "Shake to Wake" feature, but it's not. Just stopped working.

Verdaderamente excelente producto. Le queda perfecto a mi S&W MP 2.0Una excelente compra.
