i called directly Phone: (501) 724-6193 ,spoke to a brenda i think.she took my order,.told me the mail only went out on certain days of the week and it would be in the next shipment.i called back 7 or so days later to confirm shipment and got confirmation.got it put it on,love it.the factory stock is way to long and this unit has spacers.in hindsight,the MK 5 for the beretta was not in the catalogues because it was made for beretta directly.maybe because the dealers had no access was reason enough
