This is the first time in 6 years and over 20k+ rounds this gun has jammed. I think it was a magazine spring issue since the bullet (Blazer Brass 165 grain FMJ) nose dived into the bottom of the feed ramp. I was using my 10 round range magazines that I've had for 6 years. Never replaced the springs. I think they are getting weak. My 13 round carry mags still work well so I'm not concerned about that. Still though, I was a little pissed that my pistol jammed. One other thing I thought could be the problem was the recoil spring. I'm using the same spring that the pistol came with, and I know most of them last for hundreds of thousands of rounds, but I wonder if mine is a little weak. It is so easy to rack the slide. Much easier than when I first bought the pistol. I doubt this was the issue tonight as the slide did attempt to feed the round. I posted a recreated picture with a snap cap for everyone's viewing pleasure. Feel free to post your opinion. My opinion is a weak magazine spring. Thanks.
