Frequently Asked Questions

How do you remove the firing pin assembly from an IWI Masada pistol?

To remove the firing pin assembly from an IWI Masada, you'll need a 2mm punch. Press the sleeve with the U-shaped cutout at the rear of the slide while simultaneously pushing down on the back plate. Once released, you can remove the firing pin block and then the firing pin itself.

What causes a dead trigger after reassembling the IWI Masada?

A common cause for a dead trigger after reassembling the IWI Masada is the incorrect seating of the reset spring. This spring, located at the bottom of the trigger bar, must be properly recessed into the frame for the trigger to reset after firing.

How do you remove and reinstall the magazine release lever on an IWI Masada?

To remove the magazine release lever on an IWI Masada, first remove the receiver insert. Then, use a 2mm punch and hammer to drive out the retaining pin. For reinstallation, ensure the spring and green insert are in place, insert the new latch, and drive the pin back through, using the punch as a guide.

What are the key alignment points when reinstalling the receiver insert on an IWI Masada?

When reinstalling the receiver insert on an IWI Masada, four key alignment points must be considered: the serial number block at the rear, the spring seating into its hole in the frame, the trigger insertion, and the block aligning with its specific cutout in the frame.
