But the place you have to potentially compromise is in selecting what that chambering is.
That means the pistol needs to be smaller and chambered in you guessed it a pistol cartridge.
So, why would you choose to have a rifle chambered in a pistol cartridge?
Springfield Armory offers modern “cowboy guns” with the Prodigy and SAINT Victor Carbine pairing. These 9mm firearms offer compatibility in ammunition choice.
Is it worth it?
In fact, its a darn good match.
Old West cowboys perfected the concept, with their revolvers and lever-action rifles sharing ammo.
With the SAINT Victor and Prodigy, you can load the same ammunition into all of your magazines. No worries about maintaining supplies and reloading gear for multiple cartridges.
Convenience stores back then were called general stores, and they were few and far between.
They used the cartridges in their belt to top off their rifle and their pistol.
You could run out of 5.56mm and your AR-15 is downgraded to a stick.
The Springfield Armory SAINT Victor Carbine is accurate and reliable. This makes it an ideal modern cowboy carbine.
Disadvantage or Advantage?
5.56 NATO round has a muzzle velocity of about 3,250 fps.
Lets face it, a 115-gr.
The 9x19mm Parabellum cartridge is a reliable self-defense round in pistols. When shot from a carbine, velocity and energy are increased due to the longer barrel length.
9mm round has a lot less velocity at 1,500 fps.
But put the pistol caliber carbine into context.
It will most likely be used in a defensive situation.
The Springfield Armory 1911 DS Prodigy is easy to shoot, allows for the use of accessories like lights and optics, and uses double-stack magazines.
You probably wont have shots out to 75 or 100 yards.
A pistol carbine distance is a close to medium distance firearm basically spitting distance out to 50 yards.
Note: Want to see Beyond Seclusion push a SAINT Victor 9mm out hundreds of yards?
Recoil is less with a 9mm carbine, so users can more easily manage follow-up shots.
A rifle is also steadier to shoot more accurately.
Also, know what is behind your walls.
Running Federal American Eagle 115-gr.
FMJs ammo through the 5 Prodigy, velocity was 1,140 fps during my testing.
Through the SAINT Victor 9mm, it was 1258 fps.
Remington HTP defense ammo loaded with a 147-gr.
JHP had a muzzle velocity of 920 fps in the Prodigy, and 1,010 fps in the SAINT Victor.
Some Hornady Custom loaded with a 124-gr.
The longer barrel of the Victor clearly gives velocity a bump-up.
We all have different calibers for different situations, and the 9mm has a place in your AR line-up.
