The Underwood was pretty spicy. I ended up biting the bullet and purchasing a KKM Barrel. Pretty sure I’ll make no additional changes to it from this point forward.
The Holosun SCS was dead on, until I started anticipating recoil and pushing them low left. Practice needed I suppose.
Also took out my brand new G26. Felt like a cap gun compared to the G20. Love it though, pocket carry around town.
