The Holosun HS507C<\/strong> is a compact open reflex (red dot) type aiming lens, developed by Holosun Technologies. Designed primarily for direct gun mounting, it is equipped with the Multiple Reticle System (MRS), a backup solar panel and Shake Awake technology, making it one of the most versatile optics on the market in the sub-CHF 300 range. <\/p>\n\n

History and Development of the Holosun HS507C<\/h2>\n

Holosun Technologies launched the 507C series to meet the demand from the civilian and professional market for compact optics for direct-mount guns. Unlike enclosed designs like the 509 series, the HS507C is an open reflex lens: the LED emitter and the projection mirror are exposed. This architecture is lighter and less bulky, at the cost of slightly reduced debris protection. <\/p>\n

The X2 version, launched at the end of 2021, represents a significant evolution from the original. It brings a slightly enlarged viewing window, improved multi-coated glass for better light transmission, and a reinforced overall construction. The HS507C-X2 is compatible with the Holosun 507\/508 footprint which is now adopted by many pistol manufacturers, including SIG Sauer, CZ and Walther. Holosun also offers a version with ACSS Vulcan reticle in partnership with Primary Arms, offering a chevron or point with a built-in holdover scale. <\/p>\n\n

Operation and Technical Particularities<\/h2>\n

The HS507C uses a Super LED powered in parallel by a CR1632 battery and a solar panel integrated at the top of the case (Solar Failsafe). Under conditions of sufficient ambient lighting, the optics can operate indefinitely without stressing the battery. The Shake Awake function puts the device to sleep after a set rest period and instantly reactivates it as soon as motion is detected. <\/p>\n

The Multiple Reticle System allows real-time switching between three reticle configurations: 2 MOA point alone (high accuracy on distant targets), 32 MOA circle alone (fast acquisition), or a combination of both (maximum versatility). Switching between reticles requires no readjustment from scratch. The LED is the same for all three configurations, ensuring consistency of the point of impact regardless of the configuration chosen. <\/p>\n\n

Variants and Versions<\/h2>\n

The 507C series includes the standard HS507C-X2 (red dot), the HS507C-X2 green dot version (HS507C-X2 Green, less eye strain in extended use), and the HS507C-V2 ACSS Vulcan with chevron reticle developed in partnership with Primary Arms. The latter incorporates holdovers for different distances and target speeds, making the optics particularly suitable for dynamic competition. The HS507K is a miniaturized version for compact pistols with a reduced slide cut window. <\/p>\n\n

Compatibility and Mounting<\/h2>\n

The HS507C-X2 is compatible with the proprietary Holosun 507\/508 footprint, which has been adopted as a direct-mount standard by several manufacturers. It natively fits the Sauer P320 X-Series and P365 XL, CZ P-10 F OR, Walther PDP, Smith & Wesson M&P M2.0 OR, and Canik TP9 SFx SIGs. For platforms using the RMR footprint (Glock MOS, etc.), adapter boards are available. The mounting height is optimized for co-witnessing with standard fixed sights. <\/p>\n\n

Civil Possession in Switzerland<\/h2>\n

In Switzerland, the Holosun HS507C is an optical accessory and not a firearm. Its acquisition is free for any adult Swiss resident, without the need for a weapons acquisition permit. It can be mounted on any semi-automatic pistol that is legally owned. In accordance with the Federal Weapons Act (Arms Act), the acquisition of the support weapon requires an acquisition permit issued by the competent cantonal authority. The conditions include: being at least 18 years old, not being under general guardianship, and not presenting a reason for refusal within the meaning of Art. 8 (2) Arms Act. <\/p>\n\n

Conclusion<\/h2>\n

The Holosun HS507C-X2 has established itself as a benchmark in the segment of micro optics for pistols. Its excellent value for money, combined with the Solar Failsafe, Multiple Reticle System and Shake Awake technology, makes it a top choice for IPSC\/USPSA sport shooters, self-defense enthusiasts and professionals looking for reliable optics at a controlled price. Its wide compatibility with modern platforms further strengthens its status as the benchmark lens in the European and Swiss market. <\/p>\n\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"featured_media":4350,"template":"elementor_theme","meta":{"_acf_changed":false},"class_list":["post-5197","wiki","type-wiki","status-publish","has-post-thumbnail","hentry"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/wiki\/5197","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":1,"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/wiki\/5197\/revisions"}],"predecessor-version":[{"id":5199,"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/wiki\/5197\/revisions\/5199"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/media\/4350"}],"wp:attachment":[{"href":"https:\/\/nextgun.ch\/en\/wp-json\/wp\/v2\/media?parent=5197"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
