Bear in mind there's a cost involved to gear-up your gun to use the special ammo.
Pricing varies from kit to kit in the $199 to $539 range
UTM offers a wide range of kits for popular service weapons including pistols and rifle from major manufacturers such as Beretta, Colt, Heckler & Koch, Glock, SIG Sauer and Smith & Wesson. The kits come with everything necessary to get started and only require a field-strip to install. Depending on the model it may come with a complete upper assembly or it may just require a barrel and spring change.
It would be interesting to know how they feel (to shoot—not to be shot by! (just pre-empting Mr. Snurdlebaum there )
) compared to an air pistol, or even an AirSoft (not sure exactly what the difference is between those two, other than the projectile).
They say the UTM plastic projectile is only 1g, which is just over 15gr (or less than half an average .22 LR), however the average air gun pellet I think is around 7gr or so for .177 (though average .22 air pellets are more in the same ball park as the UTM at around 14 or 15gr). Velocity is another matter—the article mentions 375 fps but it's not clear if that's the rifle or pistol version. I believe that powerful air rifles get into the quadruple digits in the smaller calibers but I don't know about C02
pistols.[John—is your S&W an air pistol or AirSoft, what do you shoot out of it and do you know the velocity?]
The UTM ammo is designed to not penetrate skin. I doubt you'd have much trouble penetrating skin with a .177 lead pellet—even from a pistol.
I'm also curious about the expelled gasses too, and the need for extracting them from an indoor environment (primer only but there still must be some, I'm guessing).
So—Yes, John—I think you need to be the Guinea Pig
