Holosun 507K X2

This red dot sight is intended primarily for use on slimline pistols like the Glock 48 and 43X, Sig Sauer P365 series, S&W M&P Shield, HK SFP9 CC, Springfield Hellcat/HS Produkt H11, Walther PPS M2, etc.

It also mounts directly (no adapter plates needed) to the P365, P365X, P365XL, P365X MACRO, P365-380 and P322.

Made of 7075 aluminium with an anodised finish, water resistant up to 1 m.

The “shake awake” feature means the device will power off automatically after a few minutes of not detecting movement, and will power on immediately after detecting the slightest movement or vibration. However, we recommend turning off the device when not in use.

It comes with all the hardware necessary for its installation. We recommend applying Loctite 243 on all the screws and direct mount to a slide milled with the specific footprint of this optic (no adapter plate). The 507K-X2 has a modified Shield RMSc footprint.

This device has 3 reticle modes: 2 MOA dot, 2 MOA dot with 32 MOA ring and 32 MOA ring only.
