glock 45 mos slide cut

The Glock 45 MOS (Modular Optic System) has quickly become a favorite among both competitive shooters and everyday carry enthusiasts. Its inherent accuracy and reliability are further amplified with the addition of a red dot sight, dramatically improving target acquisition and overall shooting performance. But simply having a MOS plate isn't enough; the right slide cut is crucial for optimal optic mounting and performance. This guide dives into the world of Glock 45 MOS slide cuts, exploring the different options and helping you choose the best fit for your needs.

Understanding Glock 45 MOS Slide Cuts

The MOS system on the Glock 45 provides a convenient platform for mounting miniature red dot sights (MRDS). However, the factory slide requires the addition of an optic plate to securely attach the chosen optic. This is where slide cuts come into play. A slide cut modifies the Glock 45's slide, providing a more integrated and often more robust mounting solution for your red dot sight. There are several types of cuts to consider:

1. Standard MOS Cut:

This is the most basic modification. It involves milling the slide to accommodate the MOS plate and the chosen red dot sight. While functional, it often leaves the optic sitting relatively high above the bore, impacting co-witness capabilities (the ability to see both iron sights and the red dot).

2. Lower 1/3 Co-Witness Cut:

This cut lowers the red dot sight, allowing for a lower 1/3 co-witness with the factory iron sights. This means the top of the front sight will be visible just below the bottom edge of the red dot window. This offers a reliable backup sighting system should your red dot malfunction.

3. Absolute Co-Witness Cut:

This cut positions the red dot sight such that the iron sights are perfectly aligned with the red dot's window. This offers a clear sight picture, but some shooters find this less advantageous in close-quarters scenarios due to the higher optic position.

4. Upturned Cuts (RMR Cut, etc.):

These cuts are specifically designed for certain optic models, like the Trijicon RMR, providing a flusher, more integrated mount, often with enhanced recoil management. These can offer the lowest possible profile and are favoured by many competitive shooters.

Factors to Consider When Choosing a Glock 45 MOS Slide Cut:

  • Your Optic Choice: The type of red dot sight you plan to use will greatly influence the type of slide cut needed. Make sure the cut is compatible with your chosen optic.
  • Shooting Style: If you primarily use your Glock 45 for self-defense, a lower 1/3 co-witness cut provides a solid backup aiming system. For competitive shooting, an absolute co-witness or upturned cut might be preferred.
  • Budget: Different slide cuts have different price points. Consider your budget when making your decision.
  • Gunsmith Expertise: Ensure you choose a reputable gunsmith with experience in performing Glock slide cuts. A poorly executed cut can compromise the integrity of your firearm.

Maintaining Your Glock 45 MOS with a Slide Cut:

Regular cleaning and lubrication are critical, especially after extensive use. Pay close attention to the area around the optic mount and ensure it's free from debris that could interfere with its functionality.

Conclusion:

Choosing the right Glock 45 MOS slide cut is a crucial step in optimizing your firearm's performance. By considering the various factors outlined above, you can make an informed decision that enhances both accuracy and overall shooting experience. Remember, consulting with a qualified gunsmith is always recommended before undertaking any modifications to your firearm. The right slide cut will significantly improve your shooting and enhance your confidence in your Glock 45 MOS.
