The Ruger P series are a line of centerfire semi-automatic pistols made by Sturm, Ruger & Company. The P series pistols were designed for military, police, civilian self defense and recreational use. The designs are largely based on the Browning action found in the M1911 pistol, but with minor variations, generally related to the safety mechanism and the barrel-camblock interface. Reviews have considered them rugged, reliable, and strong, though this strength comes at the price of bulk and a blocky appearance.[2]

Design details

The P series are short recoil-operated, locked breech semi-automatic pistols. They utilize a SIG P220 type locking system, and a 1911 style tilting barrel. The P series were made with a traditional double action/single action (DA/SA), or double action only (DAO) trigger mechanism.

The standard models have an ambidextrous manual safety/decocker located on the slide; when the safety lever is lowered to the safe position, the firing pin is cammed into the slide away from the hammer, the trigger is disconnected from the sear and the hammer is decocked. The decocker models have no manual safety; instead, when the lever is lowered it only cams the firing pin into the slide and drops the hammer, when the lever is released it springs back to the normal position. The DAO models have no manual safety or decocker. All models feature an automatic firing pin safety that blocks the firing pin unless the trigger is pulled fully rearward.[3][4]

The pistols make extensive use of investment cast parts and proprietary Ruger alloys. Nearly all internal parts, including the barrel, are stainless steel; while the slide and ejector are carbon steel. The P85 through P944 use an investment cast aluminum frame, while the P95 and later models use a fiberglass-reinforced polyurethane frame.

The 9mm and .40 S&W versions use double-column box magazines; the 9mm has a 15 round capacity, and the .40 has a 10 round capacity. The .45 ACP versions use single-column magazines holding 7 rounds. All P series of the same caliber use a similar magazine design, however slight modifications have been made to at least the 9mm guns so that not all P series magazines will function in all P series frames. Ruger did not keep track of the magazine models so an older magazine may not secure in a newer frame. The Ruger Police Carbine also uses P series magazines. The P series pistols have an ambidextrous magazine release located behind the trigger guard, it can be pushed forward from either side to eject the magazine.

The P95 and earlier models have fixed, 3-dot sights; while the P97 and P345 have windage adjustable 3-dot sights.

Individual model information

Most models are or were available with blued steel or stainless steel slides, a manual safety or decocker, and DA/SA or DAO triggers. Production of DAO versions stopped in 2004.[5]

Only the manual safety, P95PR and P345 are still in production.[6]

P85/P85 MKII

The P85 was developed in 1985, but was not available until 1987.[2] It was only available with a DA/SA trigger, decocker, and a manual safety.

Early P85 pistols were recalled for a safety issue that resulted in one accidental discharge. If the firing pin broke in front of the firing pin block, applying the safety, which dropped the hammer, could transfer enough energy to the broken firing pin to cause a discharge. The P85 was recalled, and a new safety was installed that prevented contact between firing pin and hammer during a decocking operation. This modification was done free of charge. The P85 MKII was released with the safety fix, larger safety levers, improved accuracy, and the option of a stainless steel slide.[2][4]

P85 production stopped in 1990, and the P85 MKII was discontinued in 1992.[5]

P89

The P89 is an upgraded P85 MKII that introduced a number of new features; including a DAO model.

In 1991, Ruger produced a limited run P89X convertible model, which came with a second barrel and recoil spring assembly that allowed conversion between 9mm and .30 Luger calibers.

The P89 was discontinued in late 2007.[5]

P90

The P90 is a scaled up P89 chambered in .45 ACP with an aluminum frame. The P90 is considered to have above average accuracy for its price.[2]

P91

The P91 is a version of the P89 chambered in .40 S&W. It was discontinued in 2004[5]

P93, P94 and P944

The P93 is a compact 9mm model, with a shortened 4 in (100 mm) barrel and a streamlined slide and frame. The P94 is a mid-sized 9mm, with a 4.2 in (110 mm) barrel and the P93's streamlined styling. The P944 is similar externally to the P94 but chambered in .40 S&W. The P944 also introduced a camblock incorporated into the recoil spring guide rather than the M1911-style swinging link of previous version. This camblock was used on all P-series pistols designed afterward. The P91 was discontinued in 1994, and the P94 was discontinued in 2004.[5]

P95

Introduced in 1996, the P95 replaced the original P90 in production. The barrel length was reduced from 4.5" to 3.9", making it more compact than the earlier P series pistols. New models had changed from an aluminum frame to one made of fiberglass-reinforced polyurethane[7] based on Dow Chemical's "Isoplast". This reduced the weight of the pistol by 4 ounces (110 g) and reduced manufacturing costs. Unlike other polymer framed handguns on the market at the time of design, the P95 had no metal inserts in the frame. The high strength polymer allowed the slide to ride directly on the polymer frame rails which simplified manufacturing and further reduced production costs.

In December 2004, Ruger was awarded a contract for 5,000 KP95D pistols by the U.S. Army Tank-automotive and Armaments Command, Rock Island Arsenal, Illinois.[8]

P97

The P97 is based on the P95, but chambered in .45 ACP. It was only available in decocker and DAO versions.

It featured an adjustable rear sight. The front sight is pinned in, and the rear held in by a set screw. The P97 is used by a number of police departments in the United States and elsewhere.

The P97 was discontinued in 2004.[5]

P345

The P345 was released in 2004, and incorporates an integrated keyed lock that locks the safety in the safe position, a loaded chamber indicator, and a magazine disconnect that blocks the firing pin when the magazine is removed. It also has many ergonomic improvements such as a new polymer frame design (narrower than the double column derived P90 and P97) and low profile safety levers. The model P345PR adds a Picatinny rail to the frame, for mounting lights and other accessories. It was designed to be legal for sale in states that require elaborate safety measures.

The P345 was also offered in a Distributor Exclusive edition by TALO Distributors, Inc. Only 500 units were produced between October and December 2007. This model featured a unique Serial number (1-500), 24k gold embellishments, and polished blued steel slide.

Options and Model Numbers

A K prefix in the model number indicates stainless steel parts. The suffixes D indicates a decocker model, and (DAO) indicates a Double-Action-Only model. For example, a P89 with a stainless steel slide that only has a decocker would be a KP89D.

This chart lists the various options that are or were available. It only lists standard catalog items; special two tone "T" and "TH" models were and are available through special distributor deals; these models are generally sold at a slightly reduced price, include only 1 magazine, a different case, and have a blued slide on the lighter colored aluminum frame normally used for stainless models.

Table codes:

Listed magazine capacities are for full capacity factory magazines; magazine capacities may be limited to 10 rounds in some locations, and extended aftermarket magazines may hold more than the listed quantity.
