Mounting: RMSc footprint

Weight: 1.0 oz

Pros

Exceptionally long battery life

Shake Awake and Solar Backup technology

My Experience

I mounted the 507K X2 on the EDC X9L with no adapter plate required. The sight co-witnessed perfectly with the factory sights. After 800 rounds of Federal 124gr, the zero held tight. The reticle was crisp, and brightness adjustments were easy even with gloves.

How to Choose the Right Red Dot for the Wilson Combat EDC X9L

When selecting an optic for your X9L, consider the following:

Footprint Compatibility – The X9L typically accepts RMSc optics. Confirm whether your slide cut is factory RMSc or custom (RMRcc or DPP adapters are optional).

Window Size – Larger windows (DeltaPoint Pro) help with fast target acquisition; smaller ones (507K, RMRcc) conceal better.

Battery Access – Top or side-loading batteries prevent loss of zero during maintenance.

Reticle Type – Circle-dot reticles (Holosun) offer faster close-range acquisition.

Durability – Go for forged or 7075 aluminum housings for recoil resistance.

Budget vs Purpose – Premium optics (Trijicon, Leupold) for professionals; Swampfox or Holosun for budget-friendly excellence.
