3.1 Field Stripping (EP9 MDB)Updated 6 minutes ago
Regular cleaning and maintenance will ensure proper function and long life of your firearm. Before disassembling your pistol, unload and make absolutely certain that your pistol has been cleared, as described in the unloading instructions.
3.1.1 Verify your pistol is unloaded/clear and return the bolt into battery.
3.1.2 Partially push the rear take down pin from the left side so it is not captured by the detent that retains it in the receiver in the closed position. Do not attempt to drive it out with a punch. A bullet tip or other tool that will move it enough to grasp the head on the opposite side is proper procedure. (fig 4)
3.1.3 Pull the rear take down pin the rest of the way to the right side of the lower receiver until it engages the detent that holds the pin in the open position. (fig 5)

3.1.4 Grasp the front of the magazine well with a thumb up on the back of the hand guard retainer as shown in the illustration. (fig 6) Push the upper assembly forward with thumb until it lifts up in the back to a loose position and simultaneously disengages from the front retaining hook.
3.1.5 The upper and lower receiver groups are now separated; set the lower receiver group aside.
3.1.6 Move the charging handle a couple of inches to rear and remove the bolt assembly. It will simply pull straight out with no further action required.
3.1.7 Remove the firing pin retainer from the left side of the bolt carrier group. You may use a small tool to push out the firing pin retainer. (fig 7) To further aid disassembly you may need to slightly depress the firing pin to relieve tension from the firing pin spring. Before removing the retainer note its position relative to the firing pin head. It MUST be reinstalled positioned the same way. (fig 8)
3.1.8 Tilt bolt face up and remove firing pin from the bolt.
3.1.9 Remove the extractor by pulling the retaining pin up and out of the bolt while applying slight pressure onto the lateral face of the extractor. (fig 9) Please note: When reinserting the extractor retaining pin, you must insert it from the top, not the bottom. The loop must be on the top. (fig 9)

3.1.10 Your pistol is now disassembled to the point necessary for normal required cleaning and maintenance. Do not attempt disassembly of your bolt any further than herein described.
