Claw EMS Rear Sight

A few months back my buddy Matt from Down Range Firearms Training made a YouTube video about the new Claw EMS rear sight. After watching, I was interested and decided to get one in to test. I’ve had a Claw rear sight on my Glock 19 for a few months now, and I can tell you I’m impressed.

EMS stands for Emergency Manipulation Sight, and is the brainchild of Rob Pincus of I.C.E. Training. The acronym and the “claw” moniker come from the design – the sight is designed to help you manipulate the slide one-handed by catching the sight on your belt, holster or clothing.

Features and Impressions

EMS Claw – Side View

The Claw sight is made by AmeriGlo, has a .180″ wide square U notch with a similar profile to some Warren Tactical sights, and comes with a BLACKNITRIDE™ finish. At the time of writing, the claw is only being sold for various Glock models, but will soon be offered for other pistols like the Smith & Wesson M&P.

There are a lot of great sights on the market, but what makes the Claw stand out is its shape. The Claw was designed with one hand pistol manipulations in mind, and you can tell immediately when you see it. Click on the image to the right to see the curvature of the sight. This claw shape allows it to easily grab onto whatever it comes in contact with, even just clothing.

Finish and Corrosion Resistance

As mentioned, the Claw comes with a BLACKNITRIDE™ finish. Unlike some other aftermarket sights I own, I have yet to have any rusting issues with the Claw sight. I will report back if that changes this summer when the humidity is back, but so far so good.

In Use

I’ve long been a fan of 10-8 Performance sights, and honestly I can’t tell much shooting difference between the Claw EMS rear sight and my 10-8 Performance rear sight in terms of target acquisition and accuracy. I’m sure some of you will be able to tell a difference, but for me, the way I train and practice, not so much. I consider that to be a compliment to the Claw sight.

So far I haven’t been able to break the Claw EMS either. After I don’t even know how many one hand manipulations, I’ve had no problems. Again, if this changes I will report back.


Value is very high in my opinion. At the time of writing, you can purchase a Claw rear sight only for $24, which is well under a lot of the competition. I’ll be purchasing more once other pistols are supported.

Wrapping Up

If you couldn’t tell, I’m a big fan of the Claw EMS sight. Mine works as advertised, hasn’t broken or rusted, and is being sold for less than the competition. I think these are going to be extremely popular. If you own a Glock, and you haven’t replaced the crappy plastic factory rear sight, then head over to the I.C.E. Training store and pick up a Claw EMS. I think you’ll be glad you did.

    I have had mine since the NASGW show where it was installed on My G26 and i love it, it took what is an already accurate pistol and I feel it is even better now.

    What front sight are you rockin’ with it?

      Right now it’s stock. Somewhere around the house I have a 10-8 front, but I can’t for the life of me find it. I guess I’ll have to break down and buy another one.

    Agreed! It’s a great idea!

    Thanks for the info! I will look into getting one. Back when I was still a street cop 9now retired), I used to practice 1 handed and off hand manipulations. I would also have my trainees do the same – ‘homework’ assignments. This product definitely would ‘pay’ for itself if it was ever really needed.
