I FIRST SAW UM TACTICAL'S PISTOL SCOPE MOUNT MORE THAN TWO YEARS ago, but I didn't get around to buying one until this year. Now that I've tried it, I wish I'd bought one back then.
The UM3 scope mount fits on full-size handguns with standard 1913 accessory rails. The mount is T6 aluminum, weighs 2.5 ounces, and is split on top.
Inside the bottom of the mount is a spring-loaded detent that mates with the cross-slot of the pistol's accessory rail.
On top, the UM3 has six slots for scope rings and optical sight bases. The mount's bottom also has slots, two in this case, and they are designed for use with a laser or light.
Installation takes only a few seconds. The UM3 mount slides over the pistol's muzzle, and the spring-loaded detent engages with one of the pistol's accessory-rail cross-slots.
The top of the mount is held together by the sight base or scope rings.
The UM3 allows the shooter to use the pistol's sights if so desired; however, it is not compatible with elevated or tall front sights.
It is compatible with ported pistols as long as the ports vent the gas in front of the mount, not into it.
For this quick review, I employed the UM3 mount on a SIG SAUER 1911 TACOPS, and it fit like the proverbial glove. Once in place and with the scope rings tightened, the mount was extremely secure. Using my favorite Burris pistol scope, my group shooting with the pistol improved dramatically.
Specifically, using the pistol's iron sights, three factory loads averaged 3.05, 2.77, and 3.38 inches respectively for three, five-shot groups at 25 yards.
With the UM3 mount and the scope installed, those same factory loads averaged 2.13, 2.03, and 2.36 inches.
I am 55 years old, have been near-sighted my whole life, and have been using bifocal eyeglasses for about 15 years, so I'm excited about having the UM3 scope mount at my disposal.
Its easy on-and-off makes it perfect for switching from handgun to handgun, and that makes it extremely valuable to me personally.
I shoot a lot of different handguns in my line of work, and many of them are not easy to install a scope on, but shooting them with a scope would offer a better picture of their accuracy potential.
The UM3 allows me to shoot pistols with accessory rails in a manner so that my poor eyesight does not adversely affect their accuracy. Like I said at the beginning of this report, I wish I had purchased one years ago. MSRP: $99.99
