Magwell Installation

• Insure your gun is UNLOADED

• Remove the grips.

• Remove the factory hammer spring cap.

• Insure that the magwell fits over the frame and lies flat.  It if does not, minor fitting may be required.

• Install the provided hammer spring cap into the gun. 

• Test the trigger to be sure that it still functions properly.

• Start the included screw into the hammer spring cap.

• Slide the magwell over the screw head (larger side of the hole).  Keep the magwell centered over the frame as you tighten the screw using your allen/hex wrench.  Insure that the magwell sits FLAT against the frame as you finish tightening the screw.

• Tighten the screw so it is just past finger tight.  DO NOT OVER TIGHTEN THE SCREW.

• Replace the grips on the gun.   It may be necessary to remove a very small amount of material from the bottom of the grips.

• Depending on the model of Beretta that you have, a certain amount of blending will be will be necessary to seamlessly mate the intersection of the magwell and the gun.

• If you experience any problems with the screw loosening, a small amount of low strength thread locker such as Locktite 222 may be used on the screw threads before installing the magwell.

• remove grips

• remove hammer spring cap pin

• remove hammer spring cap

• remove hammer pin

• remove hammer

• reverse to replace

Insure the hammer is down.  Prop the gun on something that won't destroy the  finish (I use a hockey puck) and drive the pin out.  The punch you use to drive the pin out will prevent the cap from flying away.

PX4 trigger weight

• Factory trigger weighs between 9.5 and 10lbs.

• I can get the DA weight down to 7 to 7.5 lbs.  Any lighter and reliability will be an issue.

PX4 Sights

• Stock = 7.4mm=.291"
  Highest = 8.0=.214"
  at 25 yards, diff of about 4"
  at 15 yards, diff of about 2.5"
  at 10 yards, diff about 1.75"

92/96 Trigger Weights

• Factory F spring is about 12lbs DA and 6lbs SA

• D spring is about 10lbs DA and 5lbs SA

• Competition spring is about 9lbs DA and about 4.5lbs SA

• A trigger job will NOT reduce the DA weights any more than listed above.

• A trigger job can definitely reduce the SA weights below what is listed above.
