Friday Fundamentals – Understanding Zero for Handguns

Zeroing any firearm is the process of understanding the relationship of Point Of Aim (where the shooter aims the firearm) [POA] to Point Of Impact (where the round actually strikes the target) [POI].

For Soldiers to achieve a high level of accuracy and precision, it is critical they zero their [sighting system] to their weapon correctly. The Soldier must first achieve a consistent grouping of a series of shots, then align the mean point of impact of that grouping to the appropriate point of aim.

–Appendix E – Zeroing, Department of the Army Training Circular 3-22.9 – Rifle and Carbine, May 2016

This is the process most shooters are familiar with regarding zero. However, zeroing a fixed sighted handgun is different than zeroing a rifle.

Bottom Line up front: With rifles, we zero the sights to the ammunition. With fixed sighted handguns, we zero (adjust) the ammunition to the sights.

Spot shooting (Part II)

Yesterday, I was re-reading The Complete Book of Modern Handgunning published in 1961. It’s interesting to see how much has changed in the world of handgun shooting and how much has not.

The following gem is found in Chapter 11. How to Shoot

It brought to mind an unintentional laboratory experiment that happened while I was teaching a snub revolver class. In 2012,  I taught a short block of instruction on snub nose revolvers at the Northeast Shooters Summit, just as I did in 2011. The same block of instruction was given both Saturday and Sunday to two different groups of shooters totaling about 40. Many of these shooters had almost no experience using any revolver, much less a snub. They fired approximately 40 rounds in two hours of training, followed by a 10 round qualification course at 5 and 10 yards. The way the training was structured was shooting on dot targets until the qualification course. I emphasized the concept of spot shooting that I discussed in my previous blog post.

The target used for the qual was the TQ-21TC(C) target photo target. The value of this particular target is that it has a visible aiming point at the base of the V formed by the open throat of the jacket collar.

In both years the success rate on the qualification, using that target, was 100 percent. This mirrored my results when teaching other snub revolver classes. On Sunday of 2012, there was a target mixup and my targets were used for a class before mine. The target available for my class was the DST-1A, which has no visible aiming point on it. It is an almost solid black silhouette with a head.

The difference in the students’ success rate from previous classes was stark. Approximately 50 percent of the students failed the qualification course when it was fired on the DST-1A. Their shots were all over the targets with many complete misses. The change from defined point of aim to ‘center of mass’ aiming altered the outcome of the test radically. This occurred despite them being told to try to visualize a spot to shoot at.

As I mentioned in my previous post about Spot Shooting, using blank targets is a poor way to teach people how to shoot. Sadly, the blank target concept has become the norm. Conversely, it is interesting to note that since the Bianchi Cup (NRA Action Pistol)  switched to the AP-1 target, which has a defined aiming point, from the D-1, which doesn’t, records have been broken every year.

The ubiquitous original B-27 target at least has an X to aim at, even if it is anatomically misplaced. Something to think about in training, practice, and actual incidents is to pick an aiming point or “Mark your targets before you fire.” as Colour Sergeant Bourne put it.
