Blue, you may be on to something... Again!
I'd give this a shot--Load the mag up and shoot four or five rounds. Set the gun down, dry off your hands, get a good fresh grip and fire one shot, then set the gun down and repeat one shot at a time until they're all fired. It might be that a fresh grip on the gun will make a difference on that last shot. It'd be worth trying anyway.
I'm always prone to look at software issues (stuff I'm doing) before hardware issues (stuff the gun is doing). And I've gotten to where I hyper-analyze everything about myself. But it works for me.
I'll try to take and PM you some pics of a grip that might help. I'm not about to start a "how to hold your gun" war here, lol.
