Testing the difference with standard pressure Speer Gold Dot ammunition the difference between 9mm, .380 ACP and .38 Special. Guns used are the Diamondback DB9 3" barrel for the 9mm, the Ruger LCP 2.75" barrel for the .380 ACP and the S&W 342 PD for the .38 Special. Testing for velocity, accuracy and terminal ballistic performance. Always appreciative of any channel help :) https://www.paypal.me/gunsamrevolver
