The Overwatch Precision TAC Trigger is a flat flat-faced, direct drop-in replacement for your OEM trigger. Each trigger shoe and trigger safety tab is machined in the USA out of 7075-T6 aluminum alloy, and affixed to an NP3 plated, Gen 3 OEM trigger bar by 316 Stainless Steel coiled spring pins. The trigger shoe and safety tab are both Type III hard coat anodized to MIL-A-8625 standard. The small indexing hook ensures consistent trigger finger placement, and the broad, flat face of the trigger allows a uniquely self-correcting, straight rearward press. The flat face reduces trigger reach is by 0.24", making this an ideal option for smaller statured shooters. Pre-travel has been reduced as much as possible without compromising firearm safety features, resulting in a clean, crisp break, and reduced overtravel. Robar's NP3 plating provides virtually impermeable corrosion resistance and smooth, grit-free operation. Note that trigger pull weight does not change from factory weight with the use of this trigger alone.
NOTE: According to manufacturer, all the Gen 3 trigger bars are completely functional and safe in Gen 4 pistols
