Frequently Asked Questions

How do you zero a Holosun 507C red dot sight?

To zero a Holosun 507C, first ensure the firearm is unloaded. Aim at your target and fire a shot. Observe where the shot landed relative to your aim point. Use the adjustment turrets on the optic to move the red dot to compensate for the deviation, then fire again and repeat until your shots consistently hit your point of aim.

What are the key components of the MAC 9 DS Comp setup shown?

The setup features a Military Armament Corporation (MAC) 9 DS Comp 5-inch double-stack 1911 pistol. It is equipped with a Holosun 507C red dot sight, which includes a solar panel, and a SureFire X300 weapon-mounted light.

How does adding accessories affect the weight of a pistol?

Adding accessories like red dot sights and weapon-mounted lights significantly increases a pistol's weight. For the MAC 9 DS Comp, the addition of these items made the firearm feel 'super heavy,' even when unloaded, impacting its overall balance and handling.

What are the benefits of shooting steel targets?

Shooting steel targets provides immediate auditory and visual feedback, confirming hits. It allows for practicing speed and accuracy simultaneously, as you can quickly re-engage targets after each shot, which the speaker found very satisfying and enjoyable.
