Joe4d,
In their defense based on the rules then it is completely legal there is no way the trigger could be operated. It was sort of an off hand comment so maybe they were more thinking out loud as they visually inspected my gear.
The local club offers a variety of matches and one was a tactical rifle match that included some pistol and the other was a 3gun fund raiser match.
I am new to USPSA only mentioned production as I will be shooting my unmodified H&K USP.
Thank you for the clarifications,
Earl
