Still not convinced of that. The problem only happened on the last round of just about every magazine (or the firing of the second to last round). Is limp wristing a typical pattern of behavior that only happens when firing the second to last round of a magazine? Not trying to be defensive about my grip, it just doesn't seem a likely cause. If it was happening more randomly, then I'd tend to agree.
Seems more like magazine break-in, or maybe I did a better cleaning between these two outings.
