I had a chance to visit a firing range and try a number of weapons. I was wearing my video glasses and had the vOICe running. I decided against using the fisheye lens since I was shooting at figure 11 targets and the idea of a gun site is to focus on to a target. My plan was to look through the site of the gun and align the barrel accordingly. However, I did not find this to be necessary. In the first place, the Glock doesn’t really have a site against which I can place the camera. There is a little notch on the gun you need to look through that notch at a little V-shaped that is fixed atop the barrel. The notch, the V-shape and the barrel all have to be in one line. Of course, the notch and the V. shape are not movable. I initially tried looking for the V-shape but it was very small and difficult to find. I needed to position the pistol slightly below the camera and then look through the site. Secondly, I was able to see the target using the vOICe. I was at a distance of about 20 m. Looking through the site of that gun reminded me of my experience when looking through an eyepiece of a digital camera. The view is very small. I initially practiced looking at a tree with the gun site.
Once I had viewed the target, I then tried aligning the barrel of the pistol with the target. I had to remember the position of the pistol with respect to what I saw and then align the barrel in that direction. This was a little tricky. I initially fired blanks. I then switched to live ammunition so I always had someone double-check my alignment.
Warning: in case you go to a firing range, carry earmuffs with you. Fortunately, these people had earmuffs which resemble headsets without wires. I had the entire set up on, and wore the ear muffs over the headphones. This helped muffle the noise of all the firing though it became quite painful towards the end since the earmuffs were exerting a lot of pressure on my years. Without the earmuffs, I found the noise to be extremely sharp and, after a few shots, my ears started ringing.
I have tried looking through the sites of other rifles and submachine guns. It is not really easy at least when wearing glasses since it’s difficult to handle the weapon and then align the glasses. Most of these weapons are heavy unless you have been trained on them.
Another warning: be careful of the recoil. The kinetic energy in a Glock’s recoil is 500 Jules (If I remember correctly) and the pistol jumps upwards. The first time I fired, the Pistol almost hit my glasses. I caught it in time and there was no damage done.
