Apex Now Shipping New Flat Advanced Trigger for Sig P320

PEORIA, Ariz. – Apex Tactical Specialties is now shipping the all new Flat Advanced Trigger for the Sig Sauer P320 series of pistols. Designed to reduce trigger pull weight by approximately 2 lbs., the new trigger has an MSRP of $49.95.

The new Flat Advanced Trigger is a direct, drop-in replacement for the factory trigger and is easily installed without the need for tools or fixtures. Similar in design to Apex’s original Flat-Faced Action Enhancement Trigger, the new flat design sits slightly back compared to its predecessor, reducing the trigger reach to better accommodate those with slightly smaller hands. The flat profile puts the shooter’s finger at a natural resting position and allows the shooter to take advantage of the increased leverage.

The new trigger functions in the 9mm, .357SIG, .40S&W and .45ACP caliber versions of the Sig Sauer P320.

The Apex Flat Advanced Trigger is now shipping and available for purchase from ApexTactical.com, AIM Surplus, Brownells, Legion Precision, MidwayUSA and Rainier Arms.

Dealers wishing to stock the new trigger can order from Crow Shooting Supply and RSR, or by contacting Apex at dealer@apextactical.com or calling (623) 322-0200.

Features and Specifications:
– Reduces trigger pull weight by approximately 2 lbs.

    Can you make this for duty carry? I.E. Not reducing the trigger pull but making a flat trigger?

    That was what our first trigger, the Flat-Faced Action Enhancement Trigger for the P320, was.

    I bought my 320 just before the bang went off (no finger on the trigger) so i do the recall and i am still waiting to send it in but am not sure if i will or not ??? There is an awful lot of shooters out there that are not very happy with the repair… My Q is will i be able to use your trigger on my sig or will it only work with sigs that has had the repair done ??? I love your trigger on my glock 22 and thought i would try it on my sig but that’s when you put the trigger on hold to see what would happen with the sig deal… The thing i like is the two lb. reduction and to me the flat trigger is the best going right now… If you could get back back to me and it works on my gun i will order it real quick… Many thanks, RRL
