Vortex slide not cut properly - TRYBE Defense Sig Sauer P320 Compact Pistol Slide

The Vortex-cut slide isn't cut anywhere near the correct specification. The holes are too small for the screws and it catches slightly on bnoth ends (so the cut is too short). It also only has two 3mm pins instead of the regular four for Vortex (also Docter/Noblex/Burris etc.). Maybe it's cut to fit only a specific sight and not to the actual standard, but if so they should have spent some time in the decription pointing out that it wasn't cut to standard instead of trying to sell more Trybe garbage in the links.
