Impacts and other tweaks on our pistols

Simple sights for an early S&W revolver

Why do we have these bumps and other fabrications on our guns? Whether your pistol’s sights are literally bumps or you have a sophisticated electronic or mechanical aiming system, they are there for one reason – align the bore of the pistol with the point in the space where you would like the bullet to hit.

However, if the target is close enough, the sights are often unnecessary. Although the definition of “close” depends on the skill of the shooter and other factors such as the size of the target, the mechanical mechanics of aiming the pistol allow you to level the bore and hit the target without any interfering factor such as strong jerk of the pistol. trigger. Accuracy and ranged shots are where sight selection becomes important, whether you’re looking at the width of the fly’s blade at adjustable iron sights or the minute angle or MOA * diameter for a miniature sight or MDS.

When it comes to iron sights, the typical 0.125 inch blade width found in most factory iron sights pistols is an acceptable compromise between accuracy and speed. I prefer a thinner fly blade (say 0.115 or even 0.110 inches) because the thinner blade covers fewer targets over longer distances and is therefore more accurate. Personally, I think that fly blades wider than 0.125 are unacceptable because such a wide blade covers too much of the target at 20 yards and beyond. Manufacturers of tritium night sights often use blades that are 0.135 or wider to accommodate a tritium capsule. While these sights work well at close range, too wide a sight makes it difficult to make accurate shots at a distance.

The same is true for point size in MDS. I started my MDS training with a 6.5 MOA in the Trijicon RMR 06 red point and I still use RMR for steel matches and other short-range events over short distances. RMR 06 point size works well in the range of 25 yards or so; however, I found that the 6.5 dot covers too much of the target for accurate shots at longer distances. I now use a Holosun MDS with a 2 MOA green dot on my portable pistol and the smaller dot works very well for both short and long bullets.

Some MDS brands have multiple cross-systems, including a dot in a circle, solid triangles, open triangles with a center point, etc. Personally, I consider these crosses to be too busy and disruptive, as the only possible exception is the triangle cross. If you reset the gun / rifle for the aiming point / strike point identical to the apex of the triangle, then you have the exact aiming point (vertex) for longer distances and the rough aiming point (whole triangle) for short distances. range shots.

MDS has limitations; however, if you understand these limitations, it will work for you. But what if it rains? I wear it secretly and rain is usually not a problem because the coveralls protect my eyes from the rain until you pull out the pistol. I used MDS during a three-day Gunsite lesson and it rained heavily every day – all day. The initial MDS sight image with the water present was a bit blurry; however, the first shot cleared the water. What about batteries? Thanks to modern battery technology, it is unlikely that the battery in your MDS will fail. If you replace it with a quality battery every six months, you will almost completely eliminate this possibility.

I’ve heard a debate about whether Iron Sight or MDS is faster. In my experience, there is no practical difference for short-range collisions. I recently fired twice from a Sensible Self Defense Short Range Match – one SIG P320 Carry pistol with MDS and one SIG P320 Carry pistol equipped with iron sights. The match consisted of five phases with an average of nine target hits per phase and movement between shooting positions, etc. The distance to the targets ranged from arm length to 20 yards, and without threat or hard cover, many targets were only partially visible.

My total gross time with MDS was 78.94 seconds and my gross time with iron sights was 78.00 seconds. 0.94 second difference in favor of iron sights. Another IDPA champion, Steve, also shot a match with essentially identical Springfield XD-M pistols, once with iron sights and once with the MDS. His times were 69.60 with MDS and 71.66 with iron sights.

I have become a strong supporter of the miniature point sight on portable pistols, and due to the diversity of today’s market, the shooter has a wide range of options. I will address some of these choices in a future article.

* One minute angle or MOA equals one inch per 100 yards. Therefore, six MOA points cover 6 inches per 100 yards.
