I had a few doubts when my new G26 stacked a few. Took a few more rounds to realize the wife only was having the issues. It was limp wristing and I was able to relax my wrist enough to duplicate the issue.
Thankfully, stacks and other FTF's have been few and far between with any of my pistols going back many years. Thankfully, I've never relied on the second or third shots, but I can clear it fast and naturally if necessary.
