How much does it weigh?
Rail Mounted 1.8 ounces.
Pistol Sight 1 ounce
Does the sight have batteries?
No, this is a very simple sight requiring no maintenance or batteries.
How durable is the sight?
We mounted a Pistol sight onto a Glock, and dropped it. Click here for the video!
How does it work in low, or no light?
If you can see the target you will be able to see the reticle with the non tritium sights. Mk2 tritium lit sights are visible in day, or night conditions. 
Can you mount the sight on a pistol?
Yes, either with one of our provided dovetails, or if it has a Picatinny or Weaver rail on it you can mount a rail mounted sight onto your pistol. 
What size are the allen wrenches?
The adjusting wrench is .050. The locking wrench is 5/64. Starting around 8/1/19 the Mk2 sights started using the 5/64 as the adjustment wrench.
If I buy your sight from somewhere else can I still get a refund from you?
No, unfortunately we don’t have access to the payment method you used and therefore are unable to issue a refund. You will have to get your money back from where you purchased the sight.

Can I use a Glock dovetail on a different pistol

In most cases the answer is no. Every manufacture uses a unique dovetail, and requires a special one purpose built for their gun. In few cases some manufactures have copies another one, and in that case it would work. 



Parallax: the apparent displacement of an observed object due to a change in the position of the observer. A simple everyday example of parallax can be seen in the dashboard of motor vehicles that use a needle-style speedometer gauge. When viewed from directly in front, the speed may show exactly 60; but when viewed from the passenger seat the needle may appear to show a slightly different speed, due to the angle of viewing.

MOA: a unit of angular measurement equal to 1/60 of one degree, commonly referred to as “minute of angle,” measuring essentially the accuracy. If a shooter can fire three or five rounds and have them group inside one inch at 100 yards, then you have a “one minute of angle (MOA)” group.
