First Look: Apex Optic Mounting Plate for SIG P320

posted on June 15, 2020

Red-dot optics on pistols are quickly gaining acceptance for armed citizens and law enforcement personnel. However, mounting options can be limited, and there are new sights being offered on a regular basis. To give you more options, Apex Tactical Specialties is introducing new mounting plates for SIG Sauer P320 pistols which increase your red-dot choices for this popular pistol. Apex Tactical is known for making high-quality gear The plates are designed specifically to fit the P320 models such as the M17, M18 and Legion and they allow the user to securely mount the Aimpoint Acro P-1 optic to the slide.

The new Apex Optic Mount also fits P320 slides with a PRO slide cut (rev2), which includes the P320 XFive Legion, P320-M17, P320-M18, P320 XFull, P320 XCarry, P320 XCompact and P320 XVTAC. The mounting plate is machined from a billet of heat-treated steel and black Melonite finished for enhanced durability. The low-profile design of the mounting plate ensures co-witnessing between the suppressor height sights and the Aimpoint Acro P-1.

Apex offers three versions to choose from. The first is a mounting plate by itself, without an iron-sight option. The second and third options feature an integrated rear sight, which sits forward of the optic and co-witnesses with the included front sight.

Two front-sight height options are available, based on the barrel length of the pistol. The first model is for pistols with a 4.7-inch or shorter barrel, such as for the M17 and M18, and includes a front sight. The other is for use with 5.0-inch barreled pistols, such as the guns in the P320 Legion series. 

Features and Specifications:
– Specifically for use with P320 models with the Romeo1 Pro slide cut (rev2)
– Securely mount the Aimpoint Acro P-1
– Easy to install
– MSRP: $54.95 for P320 pistols with a 4.7 inch or shorter barrel, such as for the M17 and M18, $119.95 for pistols such as the P320 Legion with a 5-inch barrel.

Going on 40 years ago, I blundered my way into my first job in the gunwriting business. It was a function of pure, dumb luck on my part and for that, I am eternally thankful. Among the many blessings of this luck were the great people I met and the range of new experiences. Such new people included the late Chuck Karwan, my fellow Vietnam vet and as good a friend as I could possibly want.
