Shooting 6" low - FIXED!

A few weeks ago I took my new-to-me Smoke frame R51 out to the range. It was shooting 6" low at 35 feet. @%^#&*$@%!!! This was strange because my black R51 is spot on.

Then I lent it to a friend. As I was demonstrating it, I loaded a laser training cartridge into it and it was hitting dead-nuts. Huh?

Eventually, I realized that I was using the laser training cartridge with my street glasses. Tri-focals. And I was looking at them through the proper lens. When I was shooting at the range, I was using my safety glasses, with mono-focal corrective lenses. It's supposed to be the same focal point as the same lens I was using with my laser cartridge.

So I went back to the range and checked my bio-mechanics. I found that I was tilting my head down a little, in a sort of more aggressive body position, same as tucking the chin down when fighting. This aligned my eyesight through the top 1/3 of my lenses. Remember, they're mono-focal. Supposed to be the same focus no matter what part of the lens I'm looking through. But changing the point I was looking through the lens very subtly added a bit of unexpected parallax. It wasn't much but it changed my POI.

When I moved my head up to a more erect posture, my groups moved to the exact right spot.

Lesson learned.

I advocate for it too. And, even then, I was still mostly doing so. But I was letting my "fighting" stance enter in a way that wasn't appropriate to shooting. I was tucking my chin down, not to bring my eyes down to my gun, but because I tuck my chin when I fight. My best guess is that I inappropriately allowed my fighting stance to influence my other fighting stance too much and didn't notice it.

Now that I've identified the problem, I can work to fix it. :)

Heck, if i didn't need corrective lenses, it wouldn't be a problem at all. :(

Hmm... Maybe this is an argument for Pistol RD?

whats the problem. You shot the target in the neck instead of the face. Or in the dick instead of the guts

Interesting. I'll have to remember this when I'm at the rage later this week. I shoot POA/POI with two of my 9mm, the other is consistently low - by about 6 inches. And I wear trifocals - progressives. Could be at least part of the problem

Friday, while at the range, the frame on my shooting glasses broke. The bottom loop holding the right lens in. Grrr... It just randomly popped apart and dropped my lens onto the gravel. :p
