Pawpaw, if you think that is wrapped tightly, if (while I'm serving as RO) I see someone carrying an XD with the cooked striker indicator back, I will have the person face a berm, show me an empty chamber, and then drop the striker.
That is how USPSA, IDPA, 3 gun and sports are run.
It seems as if the OP is being asked to serve as RO but wants to be able to keep his firearm loaded. I don't really see the reason for this. If he is competing then just leave it unloaded like all the other competitors. If he isn't competing, then why wear a gun in the first place? If I am just RO'ing a match and not shooting then I am not wearing all of my shooting gear. Texas weather is hot, and I will avoid extra weight however possible.
