@PlantShepherd I would definitely look at Apex triggers but as far as red dot optics there are a lot of options. I chose the sig romeo1 pro for a few reasons. 1 its a perfect match and fit for my p320…2 the price was good at $400 …3 it has the motac feature which turns off the red dot after 2min of inactivity and turns back on when you puck up the gun.
If you dont want to spend the money on an optic would could was buy dawson sights for under $100. They are best night sights imo.
@Eudaemon … im a huge sig fanboy but I also love hk as well. I own a hk usp compact in 357sig and its a great shooter right out of the box.
