Like the title says - Plunger wont drop w RDS screwed on. Holosun sight, psa optic cut slide, psa included screws to affix the sight.

I think I know the screw is pressing on the plunger and preventing it from dropping out.

Dumb Qs -

will this impact reliability?

What are the fixes?

Appreciate anyone taking a read here

Pull the right side screw and file the bottom till it clears the plunger tunnel.

Or use the shorter screws that come with the holosun optic.

Appreciate it. Follow up dumb q - The dagger manual said to use dagger screws only. How does one confirm that the screw threads for the holosun 407  are compatible w the dagger slide tap? I can’t seem to find much online. dont want to muck up the tap
