Holosun HS507: why the optic matters

Mounting a Holosun HS507 on the slide transforms the Q4 SF from a traditional iron-sighted pistol into an instinctive, two-eyed shooting tool. The HS507 offers crisp reticle clarity and battery-efficient operation, speeding target acquisition in close-quarters defensive scenarios. This combination benefits shooters who prioritize rapid, accurate follow-up shots and consistent sight picture under stress.

Certified Used value and reliability

Buying Certified Used reduces the premium on a like-new firearm while maintaining quality standards. The WALTHER Q4 SF in this listing carries a “Certified Used” stamp, which guarantees the gun is in very good to excellent condition and backed by a no-questions-asked return policy — useful reassurance when purchasing a tactical pistol.

Tactical applications and user notes

With three 15-round magazines included, the WALTHER Q4 SF is well-suited to range training, home defense, and competition stages that allow optics. The original case simplifies transport and storage, and the pre-mounted HS507 eliminates guesswork when zeroing and reholstering. For those prioritizing an optic-ready semi-auto at a competitive price point, this package is compelling.
