OSA Smith & Wesson M&P Shield Optic Cut – Holosun 507K / 407K / EPS / EPS Carry
Upgrade your Smith & Wesson M&P or M&P Shield with a precision direct-milled optic cut designed for the Holosun 507K, 407K, EPS, and EPS Carry. By machining the optic directly into your factory slide, your red dot sits lower than adapter plate systems, providing a stronger mounting interface, improved durability, and a faster, more natural presentation.
Whether you're setting up an everyday carry pistol or a dedicated defensive handgun, a direct-milled slide offers the most secure and reliable way to mount your optic.

Our Thoughts
The Holosun EPS Carry and 507K have become some of our favorite optics for concealed carry pistols.
Their compact footprint, excellent battery life, and dependable performance make them an outstanding match for the slim profile of the M&P Shield family.
Rather than relying on an adapter plate, a direct-milled slide allows the optic to sit significantly lower, improving your presentation while creating a stronger, cleaner mounting solution.
The result is a pistol that feels more natural to shoot and provides greater long-term reliability.
If you're carrying your pistol every day, we believe a direct optic cut is the best way to mount your red dot.
