After installing a custom aftermarket trigger in your factory S&W® M&P®, you may experience light primer strikes, which can lead to a failure to fire. To address this well-known issue, we offer an extended striker block plunger, which has been re-engineered to ensure positive ignition.
Even without a custom aftermarket trigger, the improved geometry of our Extended Striker Block Plunger makes a great addition to noticeably improve the feel of the factory trigger.
Fits all S&W® M&P® and M&P® 2.0™ (including Compacts) any caliber. S&W® Shield™ 9/40.
Fully machined from 17-4 Stainless. Drop-in installation. Compatible with polymer and metal frame.
