I was at the range doing a little stree relief. Fired various guns and was having a good ole time. However I fired approx 200 rounds through my Browning BDA and had one round FTF first strike. The round in question was a Remington cheap green box ball. The round was approx 7-8 in the mag. All rounds before fired fine then click. I pulled the trigger DA and the round went off with the 2nd strike of the pin. Has anyone had any experience with this? This is my CCW gun and I am a little freaked out that a round failed to fire. I shot approx another 100 or so rounds after the problem without a hiccup. Also these are not my defensive rounds I am using Winchester PDX1 95 grain for CCW. Also the gun was spit shinned prior to range session clean and properly lubricated. Overall I am pretty meticulus about the condition this gun is kept in. Any ideas?
