The wider trigger shoe increases the surface area over the original. This
additional leverage allows the trigger pull to feel lighter than it actually is. The
shoes are made of aluminum and anodized in several colors.
Fits the following:
303, 390, 3901, 391, A300, A400
Fitting Instructions:
To install shoe first make sure that the small set screws are backed fully out of the
inner channel. Slide shoe over the trigger ensuring that the roll pin is behind the
bottom of the trigger (not applicable to Beretta original factory trigger) Once
aligned push shoe back to make sure it is firmly against the inside of the trigger .
Lock down the set screws. It is recommended that you apply medium thread
locker (Blue) to the set screws before you lock them down on the trigger.
Make sure that the shoe is not contacting anywhere on the trigger guard once
fitted. Always check and make sure the firearm is unloaded and safe before
attempting to fit any accessory to it. For additional information or help please call
or email Briley Manufacturing.
