Don't go by the pictures they use. Everybody uses the old stock pictures from what I see. I bought a used one that was originally purchased at Bud's in 2018 and it has the full length rails on the front, not the short tab shown in all the stock photos.
Yeah, that's what I'm guessing, but knowing my luck .... it'll be the Short Rail Slide
I know it sounds dumb, but I really like the looks of the "Full Rail" Slide over the old style
Seems that the only place using a Pic of the new Slide profile, is CZCustom
