Glock 30 Gen 4, .45 Auto, like new, one short range session

One month old. Like new condition. Includes three 10-round magazines, backstraps, and case.
Except for the added Pierce grip plug, it is in factory condition.
I took it to the range once and put 55 rounds through it. It did great. However, I decided a single-stack would fit my hands better for an EDC.
I spent $600 including tax. Asking $480. [Price reduced from $500.]

Per NM law, transfer must take place via FFL (buyer pays).
Extreme SE Albuquerque, NM [Near Four Hills]

Cash preferred. Trades considered. Looking for:
.45 ACP single stack, semi-auto handgun, full frame acceptable.
.357 magnum revolver (3-4″ barrel) or lever-action rifle.
