I am fairly new to handguns first off but consider myself a fast learner. My wife bought me an early Christmas present. The SD40VE which I love but I am having one small issue. I took my 10 year old son with me to the range to put some rounds through this gun and we had a blast. The issue was everytime I got to the last round in the mag I would get a failure to feed. I'm pretty sure this is on my part "limp wristing" or whatever it is called. Because my son only had it happen to him once. I'm thinking because he had a death grip on the gun where I was a little more relaxed. Is there something else that could be causing this?
