The Rock River Arms PPS carbine employs the company's patent-pending Performance Piston System (PPS) to reduce recoil, as well as residue in the upper receiver. It features a purpose-designed bolt carrier, an adjustable gas piston, and an over-the-barrel spring and guide rod arrangement. The result is a departure from the traditional recoil system associated with AR-style firearms. Rock River Arms is expected to offer its PPS carbine to law enforcement later in 2010; the rifle carries a suggested retail price of $1,685.

The Mossberg 590A1 is an ideal platform for personalizing a pump-action shotgun, says Mike Shain of AIMPRO Tactical. Shain is one of several shops that offer action jobs, Magnaporting, accesorization and cleaning, polishing and refinishing of police scatterguns. Vang Comp and Wilson Combat are two others that offer shotgun modifications. For less than $250, Shain can reduce felt recoil and muzzle jump, giving operators a shot pattern of 4 inches or less from 50 yards. "What can we do to hot rod this gun," Shain asks, not needing an answer. "It's a great gun out of the box, but how can we squeeze every last drop of performance out of this gun."

With all of the duty holsters available today, it's amazing to think the only option for police officers used to be black leather. Now there's also laminate, nylon, and all manner of synthetics. For finish there's basketweave, plain, or high gloss. Not to mention increasingly innovative retention devices in holsters from level 1 to 3. Here's a selection of holsters for duty carry encompassing all of these variations.

When it comes to gear and gadgets for duty applications, many of us are drawn to the coolest, most expensive items. That's true of weapons and it's true of weapon accessories such as optics. But what's more important is to find the right optics to fit your mission.
