Not a drop in - Faxon Firearms Match Series 9mm Luger, M&P 2.0 Compact Non-Threaded Pistol Barrel

Hoping optics planet and or taxon makes ths right. Tried to drop in the barrel before my range day but did not fit in my M&P 2.0 9MMC. TOOK it to my gunsmith but he told me to return or exchange it cuz they're supposed to b direct drop in barrels. I'll drop a new review shortly. After things are right.
