I, too, paid as much for shipping as I did for a pack of screws. 🤑
I went with the 94414A713 which are the same screws in 8mm length. The sight mounted up as perfectly as I could tell. Screws torqued to 15 in-lb, no gaps or light between sight and slide, windage was perfect and didn’t need adjusting at 25 yards.
I consistently don’t have the best user experience with Holosuns. My four Trijicon red dots RMR/SRO mounted to M&Ps zeroed with a couple clicks and same with one RMR on a Walther PPQ.
I’m just not sure I’m comfortable with the elevation bottomed out but it’s close enough at 25 yards that I can live with the zero.
