Load data for caliber ".32 S&W Long N.P."
The .32 S&W Long N.P. (New Police) is a centerfire revolver cartridge that is based on the .32 S&W Long cartridge. It was developed in the early 1900s as a replacement for the .32 Long Colt cartridge, which was then in use by many police departments.

The .32 S&W Long N.P. cartridge typically fires a 98- to 100-grain bullet at a muzzle velocity of around 700 to 800 feet per second. It was designed as a low-recoil cartridge suitable for use in small, lightweight revolvers, and was intended primarily for law enforcement use.

The .32 S&W Long N.P. cartridge was eventually largely replaced by more powerful cartridges such as the .38 Special, but it remains in use by some law enforcement agencies and is also popular among recreational shooters and revolver enthusiasts. It is a relatively low-power cartridge that is suitable for target shooting and small game hunting, but is not generally recommended for self-defense purposes.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
