How to Choose the Right Red Dot for Your SIRT Pistol
When choosing the ideal sight for your SIRT training pistol, consider the following:
- Footprint Compatibility
- Most SIRT slides replicate RMSc or RMR footprints. Match your optic accordingly.
- Weight and Balance
- Since the SIRT lacks recoil, balance matters more than recoil resistance. Lighter optics maintain natural point-of-aim feel.
- Dot Size
- A 3–6 MOA dot works best for indoor training distances (3–15 yards).
- Battery Access
- Top-loading batteries (like Vortex Venom) are more convenient for frequent use.
- Optical Clarity
- Look for anti-reflective coatings to avoid flare under indoor lighting.
- Mounting Simplicity
- Direct-fit optics like the RMSc and Sentinel simplify installation — ideal for non-gunsmith users.
