Rangefinders will perform differently based on changes in ambient conditions such as bright sunlight or snow, rain or fog, temperature and the reflectivity of the target being ranged.You can test reticle laser alignment by using hyperscan across a stop sign and see if there is a jump before or after the reticle passes over the item. Keep in mind that target color can also make a difference. Test known items and reflective targets to verify performance such as a reflective item at a known distance.At long distances, hyperscan mode or a tripod should be used to ensure that the target is being hit by the laser.The rangefinder is working at four times per second versus a single click at one time per second. Hyperscan mode is utilized when holding the “RANGE” button down. Since these surfaces cannot be changed, using the range finder in “hyperscan mode” which increases chances of getting a range. Some surfaces known as Lambertian surfaces can diffuse the light coming back to the range finder making ranging less accurate. All range finders are dependent on the target’s ability to reflect light back into the range finder’s receiver.When attempting to zero the laser and your adjustments are locked up or do not take effect: The P320-M17 uses a standard polymer case.

Packaging: All commemorative models will ship in the same corrugated cardboard packaging that was used for Military contract shipments. The P320-M17 includes 2EA 17rd mags.Ĭoin & Card: Each M17-Commemorative will include a limited edition coin and authenticity card with the individual serial number to be redeemed by the purchaser.

Rear sight: The commemorative model uses a one-screw design with orange tritium vials. Serial numbers: Both models will have the “M17” prefix, but the commemorative model will only have four numbers, while the P320-M17 will use six. The P320-M17 uses more standard corrosion protection such as DLC and black-passivate coatings. Slide markings: The commemorative slide is marked “Sig Sauer M17” and includes the SIG CAGE code (6ZWB1) and part number (13067008).īarrel markings: The commemorative barrel includes the SIG CAGE code under the caliber engraving.Ĭorrosive finish: The commemorative incorporates the same phosphate protection on internal parts and critical components as the contracted pistols shipped to the Military. The commemorative also uses a tamper-resistant extractor pin, just like the original contract pistols.

The commemorative model has coyote tan colored controls, while the P320-M17 comes standard with black controls. Controls: The most obvious difference is the color of the controls (trigger, slide catch lever, takedown lever, manual safety, magazine catch, extractor pin, slide plate, and sear housing).
