Unfortunately as our night vision devices have become more and more effective, they have also become more fragile to damage from recoil. The black spots in the image above are permanent damage that occurred during the firing of 5 shots of M855.
With out going into too much detail, as night vision devices been improved, the distances between some of the critical parts have gotten closer and closer. Reducing this distances has made these parts more susceptible to failure from firearm recoil. In the past it was not uncommon to see people mount night vision devices like the AN/PVS-14 on AR15s and even some 308 rifles. But now people tend to recommend against that.
Sometime I’d like to talk about selecting and using night vision, but I felt like sharing this picture now.
The AN/PAS-6 Infrared Viewing Device or Metascope was handheld infrared viewer which was used as an aid in the detection of enemy infra red sources or as a general purpose viewer.
In the 1930s, scientists developed electronic devices to detect invisible infrared light and convert it into a visible image. They also developed a special filter that could be placed over a standard light source (such as a spotlight) so that only the invisible infrared light would come through the filter to light up a target. If you had an infrared telescope, you could see objects illuminated by the infrared light source. Of course, if the enemy had an infrared scope, they could see your light source, without giving away their own position. The U.S. Army’s first successful units, like the one shown here were used in Okinawa in April, 1945. Later types used in Korea, and into the mid-1960s include the Metascope. Typical range of an infrared light source for a rifle is only 100-150 yards. The scope will show a dimly visible image like a small black and green TV image. – modernforces.com
The viewer above was used in the Vietnam war by some SOG personnel at fixed locations. Reportedly one location was Leghorn, a very high peak in Laos that SOG set up a permanent radio relay and observation site. The viewer would be able to detect communist troops at night or other sources of infrared.
On January 17, 2017 Sig-Sauer was declared the winner
of the Army Modular Handgun System (MHS) competition. Sig-Sauer’s P320 based
M17 / M18 design beat out designs from Beretta, FN, Glock, CZ and Smith & Wesson
to name a few.
In addition to fielding new pistols, the Army is
fielding an entire ‘system’ of accessories that include a holster kit
manufactured by Safariland and a new family of ammunition consisting of five
different rounds. The ammunition in the program is the M1152 full metal jacket
(FMJ), M1153 Special Purpose, M1156 Dummy, a Drill round and an inert round.
The Army also wanted a Pistol Aiming Laser (PAiL) for the warfighter that would
provide the soldier with a white light, infrared light (IR) and an IR aiming
On September 5, 2018, the Product Manager, Soldier
Precision Targeting Devices (PdM SPTD), located at Ft. Belvoir, Virginia
published a Request For Information (RFI) for Competitive Procurement. The RFI
requested data from potential sources for a Pistol Aiming Laser (PAiL) with
Laser/white light Illuminator, that meets performance requirements set forth in
the Modular Handgun System Capabilities Production Document Addendum for the
Pistol Aiming Laser Module.
To find the soldier a light with the desired capabilities, the Army conducted an evaluation between the LaserMaxDefense (LMD) Pistol Enhancer (LMD-PE-IR-1) and the Streamlight TLR-VIR-II weapon light. Evaluation of the offerings by LMD and Streamlight took place in the summer of 2018.

There has been some discussion on the internet as to why the DoD didn’t select an existing, proven weapon light like the Surefire X300 or X400. These two lights were disqualified from consideration for the PAiL requirement because one of the design requirements in the DoD industry solicitation was for the pistol aiming lights submitted for evaluation to not extend past the muzzle of the M17/M18 pistol. Here are a few photos that I took to demonstrate the differences in light profiles.
On January 17, 2019 LaserMaxDefense (LMD) announced that they were awarded an initial contract from the U.S. Army for 20,000 Pistol Enhancers. The PAiL is being fielded in a kit that consists of the M17 pistol, a Pistol Enhancer and a specially designed holster from Safariland shown in the following photo.

A U.S. Army Infantry company was authorized nine M9
Beretta pistols. Under the Modular Handgun System fielding plan, Army pistol
authorizations increased to 46 pistols in the an Infantry company. Pistols are
being assigned to soldiers in leadership positions from the Team Leader level
up to the Commander and First Sergeant. Each pistol issued in an Infantry
company will be issued with a PAiL and holster.
Some of the more notable features of the LMD Pistol
compartment is on the bottom of the light body. This enables the battery to be
changed without removal from the pistol. This ensures retention of laser zero.
* The laser is located inline with bore of the pistol
increasing accuracy once zeroed.
* The windage and elevation can be adjusted with a slotted screwdriver or multi-tool.
The multi-position switch on the left side of the PAiL
has the following functions:
dot- White light
dot- IR light and IR laser
The black button at the rear/top of the PAiL body on
the left and right side is the main on/off switch for the unit. It is easily
manipulated from each side with the index finger.
One item that seems to be complained about by soldiers
using the PAiL is that the IR aiming laser is on anytime that the IR light is
on. The IR laser/light cannot function separately from each other.
The LaserMaxDefense Pistol Enhancer comes in a small, sturdy cardboard box. Inside the box is a pink bubble-wrap envelope that contains the Pistol Enhancer, a clear ziploc bag with one CR123 battery and one Pistol Enhancer booklet.
The U.S. Army does not have a separate Technical Manual (TM) at this time and the LMD booklet fills the role of TM at this time. Here are some excerpts from the booklet.
Overall, The LaserMaxDefense (LMD) Pistol Ehancer/PAiL brings a compact improvement in functionality to the M17/M18 pistol as part of the MHS fielding program. The integration of the aiming laser into the light unit could translate to faster target acquisition and increased lethality once the PAiL sees use in a combat environment.
The features of the Pistol Enhancer/PAiL are:
175 lumens (typical) of white light
175 mW (typical) of 850nm illumination
850nm 0.7 mW max (class1) eye safe aiming laser
< 1.4″ (not below trigger guard)
2.6 ounces with battery
Glass filled nylon can be in black, desert tan, or FDE
3 position rotary switch
Tactile feel button located on both sides of the unit for easy
location in the dark. Single tap on single tap off + Momentary.
Single CR123 reduces previous battery requirement by 50%
2 hours continuous in any mode
Bore sight retention:
within 4 inches at 50 yards
-10° to 50° Celsius
1 Meter for 30 Minutes
$349 per unit
Currently the LMD Pistol Enhancer is only available to
the U.S. Department of Defense, government agencies, law enforcement agencies.
Personnel that work for a DoD, government or LE agency can also purchase the
units by contacting LaserMaxDefense from a DoD/government/agency email account.
There is some discussion of a revised PAiL for the
civilian market. I think a version with a visible laser in place of the IR
laser would be a popular accessory purchase by people who have had the
opportunity to purchase one of the Sig-Sauer M17 Surplus pistols that came onto
the civilian firearms market in 2019. I have used my personally purchased LMD
Pistol Enhancer and Sig-Sauer M17 Surplus pistol in the photos in this article.
For owners of the Sig-Sauer M17 Surplus pistol, there
is Facebook group dedicated to these pistols and accessories at:
