Gents, I ran a couple hundred gold dot 147s on top of 5gr of power pistol and some factory 115s to see how the hackethorn will regulate.
The sights are listed as fitting all the bigger common glocks but not the single stacks. They work great for me. Rear has about .035" of slide beyond the sight on each side and elevation was as good as i can shoot at 25 and 50 yards.
If you haven't tried these sights, they are the greatest I've used for a gun that needs to have night abilities but accuracy during light is important.
All rounds were fired from the s15 mags without a problem but they are a biche to load 15 into.
