The shooter in the above linked video is one heck of a remarkable shooter.
I was amazed at how accurate my first Springfield Armory 1911-A1 .45 Auto was. It's a Loaded Model. I sold all of my other 1911-A1s. Now I own only Springfield Armory 1911-A1s.
For clarity, I bought a Springfield Armory Loaded Model as between-trout-bites entertainment for my kids. That gun has been nothing short of flawless. At the years ago price I paid, it was an incredible bargain. The Loaded Model is worth far more than Springfield Armory's MSRP.
Because of my 100% positive experience with my Loaded Model, I bought a Springfield Armory TRP .45 for use as my primary wilderness handgun. We've run across HUGE black bears while chasing trout. Avoidance is our primary mean critter strategy. If a bear is in one of our fishing spots, we'll go to another. If a bear were to wander into a spot we're fishing, we'll wander out. However, as a parent, my highest priority is protecting my kids. Should any bear get a notion that my kids are on its dining menu, it'll get 8 230 grain Fed HST LE rounds. I needed a 100% reliable handgun to protect my kids. For many reasons, the Springfield Armory TRP was a no-brainer for me. I completely understand other fishermen/ourdoorsmen going with what works best for them.
BTW, I could've used my Loaded Model for black bear defense. However, since water is necessary for catching trout, I wanted Springfield Armory's Armory Kote. While I've been lucky to date by keeping water, mud, etc off of my TRP, sooner or later it will endure trout fishing elements. Armory Kote allows me to carry it for a week or monger without worrying about rust.
After I bought my Springfield Armory TRP .45 Auto, I was at a rifle range sighting in a center fire rifle. My target was a hundred yards distant. After I assured my rifles was sighted correctly, I awaited for the range to clear to retrieve my target. Since I was doing nothing but waiting, I fired about a dozen rounds out of my TRP at my rifle target. I did use a rest. I didn't think I'd hit my target, mostly due to the rainbow arc of the .45 Auto cartridge at that range. I held about a foot high. and fired. I'll merely write that I was astonished by my TRP's 100 yard performance.
My Springfield Armory EMP 3 could make a novice look like an accomplished target shooter. For a small handgun, it is unfathomably accurate. It replaced my decades old S&W Model 60 as my carry gun that I very rarely carry. The Model 60 and its sister, the Model 36, were old school, perfunctory off-duty handguns. The Model 60 is a very good and easily concealed handgun. But it has what could be fatal limitations. For self-defense, the EMP 3 is geometrically superior to the Model 60. BTW, my Model 60 is one of three revolvers with which I've experienced catastrophic failure, meaning that if I had been confronted with a survival situation, I would have been armed with a throwing weapon.
I used to be a Sig P series (all metal) loyalist when it came to handgun accuracy until I bought my first Springfield Armory 1911-A1. I still love SIg handguns, but not as much as I love my Springfield Armory 1911-A1s. Based upon my experience, Sig P series handguns and Springfield Armory 1911-A1 handguns are 100% reliable. I have zero knowledge of other Sig and SA handguns.
