Though there are many Glock®trigger upgrades available today, every other company came after Zev Technologies, the first company to develop aftermarket triggers for these popular guns. Now, Zev's engineers are maintaining the company's position as an industry leader with the introduction of Zev Technologies Glock®PRO Flat Face Drop-In Trigger Kit. After spending thousands of hours and hundreds of thousands of rounds in development time, the Zev PRO Flat Face Drop-In Trigger Kit incorporates many cutting-edge advancements, like a proprietary trigger-bar design and a new connector, all designed to produce a trigger pull that's crisper and cleaner than ever before. Durability is also enhanced in the Zev PRO Flat Face Drop-In Trigger Kit, thanks to a trigger pad produced through a riveted production process, making it one of the hardiest and most-reliable designs available today.
