• Police shotguns do not have an ISS (Integrated Safety System) which is a locking
mechanism on the safety of commercial shotguns. This type of locking mechanism
can cause delay to an officer who needs the weapon but does not have the
appropriate key. LE shotguns have the standard, proven, cross bolt safety.
Express guns no longer have the "J" lock/ISS lock
• The Express model will not allow for the addition of an extension tube without
physical modification to the tube and barrel, which can nullify the warranty.
Recent production Express guns I have seen no longer have the "dimples" in the magazine tube
• The Express model utilizes a synthetic trigger housing while the Police models use a
compressed metal housing.
Police guns now have the polymer trigger plate (housing)
• The Police shotgun barrel is locked down with a “ball detent” system in conjunction
with the magazine cap vs. a lesser grade “synthetic magazine spring retainer” lock
down as used on the Express system.
Recent production Express barrels I have seen again have the ball detent to retain the magazine cap
