Why Steel Matters
When you mount an optic on your handgun, especially a carry or duty gun, failure isn’t an option. Steel plates offer more strength, less flex, and better heat resistance than aluminum. They also let you keep a lower profile, reducing bulk and helping co-witness with suppressor-height iron sights.
- Holds zero better under recoil
- Less flex than aluminum - optic stays rock solid
- Thinner profile = lower optic height = better sight picture
- Heat resistant and more durable over time
- Built to survive thousands of rounds, not just range days
