Optic Review: C&H DMO and Comp Red Dot Sights

C&H Precision made its name milling slides and making adapter plates for red dot sights. They still do all of that, but about a year ago, they came out with their own line of reflex sights and so far, the models they’ve introduced are very competitive.

While C&H offers optics with a variety of features and in a range of footprints, their latest innovation is their Direct Mount Optic line that lets you ditch the use of an optic plate if you’re running a gun from one of seven of the post popular pistol makers (CZ, GLOCK, HK, SIG SAUER, Smith & Wesson, Taurus and Walther).

The C&H Precision Direct Mount Optic for GLOCK on a GLOCK 19 Gen5 MOS pistol.

Seen here is the C&H DMO for the GLOCK MOS mounting system. The GLOCK optic mounting system works well, but requires the use of a plate. That means raising the height of the sight and, depending on the iron sights you’re using, losing the ability to co-witness.

The 3 MOA dot is easily visible, even in bright daylight.

The C&H DMO allows you to screw the reflex sight right onto the GLOCK MOS slide without the need for an adapter plate. That makes things simpler, takes away a potential failure point, and keeps your iron sights in play.

Brightness adjustments (there are ten, with two night vision compatible) are made using simple rubber up and down buttons on the left side. Windage and elevation adjustments are made with small flathead screws so you don’t need to keep a tiny Allen key around. You can make adjustments with the tip of your pocket knife.

The 1632 battery can be swapped out through a door on the right side, meaning you don’t have to un-mount the sight and re-zero when your battery dies. The good news is that won’t happen often as the sight has “motion control” (aka shake-awake) that shuts down after five minutes of inactivity. The sight is rated at up to to 50,000 hours of battery life and is available with either a red or green dot.

The sight is tough, too. I’ve banged it around both on the range and in carrying it on an everyday basis for a while now and its 7075 aluminum housing hasn’t missed a beat. There’s also no lag or flicker. You can move from target to target smoothly.

I’ve also been shooting C&H’s Comp red dot. The Comp comes only in an RMR mount version and this one has been riding on my Lone Wolf Dusk 9mm pistol.

As you’d expect from a competition red dot, the Comp’s window is noticeably larger than the EDC-focused DMO sight.

That said, it’s not like the comp is inordinately large or unwieldy. I’ve carried it concealed, too and it performs just fine in that role.

Like C&H’s smaller DMO reflex sight, the Comp has a 3 MOA red dot with 10 brightness settings, (two of which are night vision-compatible). You can get one with a red or greed dot as well as a multi-reticle model. 

In fact, those who are pistol red dot skeptics and worry about finding the dot in a high pressure, personal defense situation would likely do much better with the Comp on their EDC gun with its larger window. The Comp’s lens is 28% bigger (27mm vs. 21mm) than the DMO’s.

The comp also runs on a 1632 battery, has Motion Control and is rated at 50,000 of average runtime.
