I’ve got a vp9 (optics ready) that I just bought a Leupold Deltapoint red dot for. It should arrive later next week. As I understand I need taller sights to be able to cowitness. I found some sights that say optics ready sights but they don’t look any taller than the factory sights. I’ve found some that say suppressor height sights and they clearly look taller. Are the optics ready just a different mounting size or will they work with the red dot and not a suppressor? I’ve tried googling and haven’t found anything that clarifies . What sights are you all using with your red dots?
