Joseph - Buds often uses stock photos that do not accurately depict all the details of any particular model firearm being sold. When I checked, the picture on the Taurus Company web site shows two rail slots in this pistol (exact same model # and exact same UPC) just, as you said on YouTube. See: taurususa.com/firearms/pistols/92/92-pistols-9mm-17-round-2/ I am confident that while the picture on Buds web site is different, this is the pistol one would actually receive.

Joseph, this looks to be an older stock photo. I would still verify the # of notches with Buds Customer Service at 1-859-368-0371 9am-9pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 9pm Mon-Sat and 11am - 7pm Sun (7 days a week).
