It’s quite compact and ultra lightweight at 2.7 x 1.2 x 2 inches and the weight of 2.88 oz.

It’s powered by 1 CR2 battery that comes with the rest. The 125 lumens output of this tactical flashlight can be considered a downside, as it’s not nearly as much as other lights offer. On the other hand, the red laser boasts power output of 5mW, which is maximum among Class 3R Red Lasers. If you switch the device to laser only, it lasts up for as long as 11 hours.

This rail mounted laser/tactical flashlight comes with an ambidextrous momentary/steady on and off switch and it can be mounted quickly and easily and thanks to the rail locating keys, it can be mounted almost on any handgun with Picatinny or Glock style rails.

LASER BASICS

 

 So, let’s say you decide to purchase a laser for your Glock 21 C. They enhance the performance and can help people finding and keeping the target in aim especially if their eyesight is not in top condition. Let us give you some basic knowledge about what rail lasers are and how they work. A laser (not only handgun lasers, but lasers in general) is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". To put it shortly - making the beam of light small and amplified.

Handgun Laser Pros

There are many applications for lasers in many areas and one of them is our favorite area - the firearm area. A laser sight is a small and visible laser, that is placed on a firearm and aligned to emit a beam parallel to the barrel. The alignment then finds the target in the distance and enhances its visibility and trackability for the user. A laser beam has low divergence, that means that the spot appears even at long distances. The main advantage is enhancement of the target.

Handgun Laser Cons

Using a laser may distract you from proper aim training. You won’t have the ability to use it all the time so it’s best to also practice aiming without a laser. Especially close distances and flash situations may obstruct your laser usage. Another small disadvantage of the laser is that you have to have some factors in mind - specifically bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while the bullet travels. This may sound like a lot of things to remember, but they are required to have in mind while using a laser.

RED VS. GREEN LASER COMPARISON

 

 Lasers are still one of the top accessories you can add to your Glock 21 C to enhance the performance of you and the firearm as well. Lasers come in two variants - red and green. Each has its pros and cons and you can read more about them in the article below.

Understanding lasers means understanding how they work. They have to correlate with the visible light spectrum of the human eye, red light waves range from 620 to 750 nanometers, and green light ranges from 495 to 570 nanometers. Although the red light covers a larger spectrum, the human eye is more likely to recognize colors of the green spectrum. That means that green lasers are more “natural” to the eye to recognize in all light conditions from midday to midnight.

However, the catch is that red lasers are easy to manufacture, requiring only a diode, optics and basic electronics. Green lasers on the other hand are something like nuclear physics when compared to red ones. They require a special diode, a infrared crystal and another frequency-doubling crystal, as green light needs its frequencies to be enhanced. This makes the manufacture more costly, lengthy and the whole product is packed in a larger package.

So, to give an answer to the question red vs. green we have to go down to two things, personal preference and budget. Red lasers are the right choice for you if you are looking for a slight enhancement and your funds are limited. The spectrum and natural recognition of red lasers is relatively good, it has only a midday downside, and the package is smaller and cheaper. Green lasers on the other hand are the choice for you if you are looking for a professional laser sight and your budget is not limited. The green laser outperformed the red one but takes a small toll on your wallet.

Glock 21 C LASER TRAINING BOOKS

 

One of the key things to remember is regular and repeated practice. Sig Sauer P226 laser training is best practiced while being supervised by a professional, be it on the range or anywhere else. If you can’t afford a specialist you can always find good resources in books. Tactical training books and how to’s are one step in your way of training. Yes, you can find loads of articles online, but a book is tough to beat.
