WHY 9 IS STRONG
Most know that 9mm self-loaders are common. On the other hand, Ar-type pistols are not so common.
The adoption of 9mm for SMGS (often called machine pistols) began prior to World War II. After the war, 9mm SMGS and pistols became practically universal with NATO countries. (The Thompson and M3 .45 were in use with the United States until at least the Vietnam War.)
The adoption of the 5.56mm rifle finally gave United States soldiers a go-anywhere, do-anything long gun that was useful for precision fire as a rifle and area fire as an automatic rifle. It replaced the 9mm sub-machinegun. For many years that is where the situation stood. The superiority of the 5.56mm cartridge made the 9mm SMG obsolete. Then Colt responded to LEO requests for a 9mm AR to fill a traditional SMG niche. Less expensive than the Heckler & Koch MP5, the Colt 9mm SMG enjoyed some popularity but was eclipsed by 5.56mm variants.
Today there are 9mm AR conversions available, and there are many good reasons for owning a 9mm AR. The 9mm offers inexpensive practice, ammunition that is available everywhere, and it provides good accuracy up to 100 yards—or even a little more.
Admittedly, I have been resistant to the concept of a 9mm AR based on the superior power, accuracy and wound potential of the 5.56mm. That’s fine for LEO and others, but for most of us, the 9mm does just fine. My friend Darrell has a great deal of experience with the AR, including military experience, and he enjoys his 9mm AR. He asked me what the likelihood of me needing the rifle in a personal defense engagement or for hunting game. I had to admit that it was pretty slim … and I had other rifles for those chores.
He also asked if I had used a rifle during critical engagements. During that time in my life, it was the rifle and the shotgun. The AR pistol is a great recreational handgun, he said, and this is true and more than enough reason for choosing the 9mm.
On the other hand, if personal defense is the chore, the Wilson Combat AR9 is far superior to standard handguns and will give a homeowner an edge in a defensive situation. For area or site defense, the AR pistol has many advantages, including increased range over a shotgun.
It does not surprise me that Wilson made this. The Ar-type pistol is very popular so it makes a lot of sense that a 9mm Ar-pistol variant would be introduced. The 9mm offers inexpensive, easily found ammunition; and good maneuverability in tight quarters, such as vehicle defense and in the home. This is an ideal role for a short, fast-handling AR.
The 9mm has the advantage of less flash and blast, and light recoil, too. The 9mm with the most powerful loads offers good wound potential, more so from the AR pistol’s longer barrel. There are firing ranges that prohibit rifles and rifle-caliber pistols, but the 9mm AR pistol is just fine.
This allows more practice. As an example, my pistol range is less than 20 minutes away, but the rifle range is a solid hour. There are also a number of venues for competition with the 9mm AR rifle and the AR pistol, as well. An Ar-type platform is far more accurate than the Uzi-type pistol and most 9mm carbines. The AR9 is a credible piece, well-made, and with more applications than we might first think.
