Maybe ask yourself, "what is the consequence of failure?" and if you are honest with yourself, the answer will be "nuthin". You should, and I suspect you do, have no expectation of winning. So if you have an ammo problem, you will not win. If you do not have an ammo problem, you will not win. Your reloads are proven, I recently bought a Ruger 9mm 1911 and probably am 1k rounds in, and I think the only FTF/FTE type issue was with WBW from Walmart.
Yup, and like I said, you are not going to win your first match, so the sooner you get that behind you the better
