I had 3 ftf in 21 rounds in 9mm. I was testing a new gun so was bummed thinking it was the gun. So I came home and Googled:"Hornady Critical Defense light strike." There are numerous threads including about any handgun brand you can think of. I figured that I'd find this issue with the Kel Tec pistols in the search as that is what I was using. I also found this: http://tjofsugarland.blogspot.com/2009/11/hornady-critical-defense-ammo.html and this: http://tjofsugarland.blogspot.com/ If you use this ammo make very sure you have no issues. Even the Rohrbaugh that costs 1,200 bucks have had ftf with this ammo. Some people are having no problem but the amount that have is amazing. Remington UMC ammo worked perfectly in the 56 rounds I fired. I'm not putting anything or any firearms down. I just want to make sure people do research before they buy any SD ammo, especially this one. I wish I had.
