Twenty-Ninth in a series of a quest to find the overall best defensive ammunition for modern 9mm pocket pistols (such as the Sig Sauer P938, Taurus PT709, the Ruger LC9, Kahr CM9, Beretta Nano, Kel-Tec PF9 or S&W Shield or any other popular 9mm micro-pistol using a barrel length of approximately 3").
In this test, I fired three bullets from the 3" barrel into a denim-covered gel block, and witnessed three complete fails. I then used the remaining room in the block to test the other guns, firing one round from the 4" gun (which also clogged and failed to expand) and one round from the 6" gun (which performed perfectly and penetrated to an excellent 16.75" depth).
I then fired three more rounds from the 3" barrel into a block of bare gel and witnessed another example of poor performance, with all three bullets only partly expanding, while the rest of the bullet sheared off, leaving chunks of bullet throughout the block. I then fired a bullet from the 4" gun, which performed excellently, and then one from the 6" gun, which also performed excellently.
My conclusions are simple: avoid this ammo if you're using a 3" or 4"-barreled gun. This ammo says right on the box, "Law Enforcement Duty Ammunition." They're not kidding. This ammo appears to only work properly from a full-sized, duty-style pistol. If you have a gun with at least a 4.6" barrel, such as a Glock 17, or, better yet, a 5.3" barrel like the Glock 17L, then this ammo might be great. But for anyone using a shorter barrel, this ammo appears to be a poor choice. Stick with regular Gold Dots or Short Barrel Gold Dots for the smaller pistols.
