I did not include the expanded round from the CZ as it was the basically the same as from the C9Īs you can see a given round does gain velocity and expansion from the longer barrel (as expected). The expanded bullet on the left is from the C9 and the one on the right is from the 996TS. Here are the rounds dug from the gel as well as one unfired for comparison. That velocity gain equated to additional expansion and a little less penetration.
Please click on the chart for a larger version.Īs expected there was a small velocity gain from the Hi Point C9 to the CZ 75B but also there was a substantial velocity gain when fired from the Hi Point 995TS carbine. The cloth is similar to khaki work pants. Since this is primarily a defensive experiment I opted to shoot the ballistic gel with the 3 layers of cloth over the end. This is a pretty straight forward experiment using a selection of factory defensive rounds with known performance shot over the chronograph to track the feet per second difference and into ballistic gel to illustrate what that change in velocity equates to. With the longer barrel the bullet has more time in the bore allowing the propellent, as it detonates and produces gas, to provide continued acceleration of the bullet. Of course we all know the benefits of a handgun, relatively small and easy to carry/conceal but with that size comes the drawback of lessened energy even when comparing a pistol to a carbine in the same caliber. You can read more on the 9mm Luger ballistic test in this link. Adding in the CZ 75B Omega as another 9mm pistol with a somewhat longer barrel than the C9. So I figured I would take some of the better performing rounds from the 9mm Luger ballistic test and make the comparison. I have received, as test samples, a Hi Point 916 C9 pistol chambered in 9mm Luger as well as a Hi Point 995TS carbine chambered in 9mm Luger. Is it worth the extra investment to have a carbine chambered in a handgun caliber for home defense or a “truck gun”? Many prefer a pistol for day to day carry and understandably so. It is not feasible to always carry a carbine or rifle as a defensive weapon.
Pistol vs Carbine differences ammunition performance, and it is enough to really matter?
