Laserlyte’s Rear Sight Laser

This small, compact unit combines a fixed rear sight with an adjustable laser.

The fact that I am even writing this attests to my willingness to change even though I normally dig in both heels and resist dramatically to anything affecting my preconceived notions. It was not too many years ago any “real sixgunner” would look down his nose at anything so lowly as a 9mm, let alone a 9mm Glock. I made much of what little reputation I have now shooting big-bore, really big-bore sixguns and reporting about them. Long before I started writing and over many decades virtually every writer did the standard .45 ACP vs. 9mm argument with the latter always losing. By the 1980s, that was about to change.

Two things happened and those two things were Glock and the introduction of ammunition, which was certainly well above the standard 9mm hardball. Many concluded the high-quality 9mm loads being offered were at least on par with the legendary stopping power of .45 hardball. I accepted the ammunition long before the Glock and one of my favorite concealed carry guns was the Smith & Wesson Model 3913 loaded with 9mm hollowpoints. It was not high capacity, however it tucked in behind my belt and stayed there. It is still always loaded and always close at hand. Slowly but surely I began to accept the Glock for what it was. I mostly look at firearms as not only useful tools but works of art. The classic lines of the Colt Single Action, Ruger Flat-Top, Smith & Wesson’s .44 Magnum and Combat Magnum, and the 1911 are all highly efficient and—just as important to me—eye pleasing and worthy of custom stocks; even engraving.

It was not until I attended a Glock Seminar divided between classroom and actual shooting conditions that I really appreciated the Glock for what it was. Over a 3-day period I fired 1,000 rounds of .45 ACP ammunition and the Glock never hesitated, never failed to feed, and I never missed a target. My anti-Glock armor was cracked wide open. Glocks in .45 ACP, .45 GAP, and 10mm were soon added to my shooting battery and although they worked perfectly I normally went with something smaller for concealed carry. This past year found me looking through the Glock Annual where I discovered the 15-shot Model 19C (“C” for compensated) 9mm. To me this looked like the perfect answer for a high-capacity, easy-to-carry 9mm with a compensator making it even easier to control in rapid fire. It came with excellent sights with the rear sight in a dovetail and adjustable for windage.

It shoots extremely well with very little recoil making follow-up shots, if necessary, very easy; it was just about perfect. Only one thing remained to finish up this highly efficient self-defense tool and that was to add laser sights. Self-defense situations most often occur in low light making a laser a most valuable add-on. The answer in this case is the LaserLyte Rear Sight. I have several laser-equipped semi-automatics and double-action revolvers. For most of them the laser is in a replacement grip or attaches to the factory grip, or in one case replaces the guide rod on a 1911. The LaserLyte is none of these. It is in fact an extremely compact replacement rear sight.

The Rear Sight Laser from LaserLyte is designed to fit all Glocks simply by tapping out the factory rear sight in its dovetail and replacing it with the LaserLyte combination rear sight and laser. The replacement rear sight is a white outlined square blade, which matches up perfectly with the factory front sight and works as well or better than the original rear sight. On both sides of the rear sight blade we find two cylinders approximately 1/4″ in diameter and 3/4″ in length. The left cylinder contains the battery and activation switch while the right cylinder is the laser. The latter is adjusted by an elevation screw on top, and a windage screw on the side. It is extremely compact and does not interfere with holstering nor does it change the grip in any way.

Most lasers have an off/on the switch which must be turned to the “on” position and then the laser itself is activated by hand contact with the laser grip; the LaserLyte is different. When the activation button is pressed once a solid red laser light comes on while twice gives a pulsating feature and then pushing the button the third time turns off the unit. To activate the LaserLyte you simply draw the pistol from holster or waistband, bring it up to the normal 2-handed position where the offhand thumb presses the activation switch on the left side of the rear sight. If one hand or arm is out of commission in an emergency I find I can use the thumb of my shooting hand to reach the activation switch by propping the pistol against my other arm or any solid surface.

The LaserLyte Rear Sight weighs just over 1 ounce and uses four very small 4×377 batteries. In constant use these batteries will last 5 hours in regular mode and double that when using the pulsating mode. The LaserLyte Rear Sight comes with one of the best sets of easy-to-follow and exceptionally well illustrated directions available, as well as batteries, two Allen wrenches for adjusting the laser as well as tightening the locking screw of the rear sight, and a brass punch to tap in the rear sight without having to worry about scratching it. The sight is also available for the Springfield Armory XD.

    I bought the rear sight laser for my sigma 40 ve and mounted the sight. I shot and sighted in the rear sight and attempted to sight in the laser but could not get the laser to move in any direction. Is there any warranty or any way I can send it in to be looked at. Thanks
