If Wilson has had your gun over a week, I would be calling them they are pretty damn quick in turnaround. I fortunately have never had the problems that you describe, the ONLY HP ammo I had malfunction has been Hornady TAP FPD, my 1911's each ran over 100 flawless rounds and then choked, my Nighthawk Commander is the only one that has fed over 200 flawless rounds of that, but I only use it in my Glock, I think it has something to do with the coating on the case, hell I do not know but when I have any question about ammo I do not use it
If you have not tried Remington Golden saber 230 Grain, give it a shot, something about the design of the projectile makes it extremely reliable and i have fired 1000's of rounds of it with no problems whatsoever,
