SIG Sauer P250

The SIG Sauer P250 is a semi-automatic pistol made by Sigarms (now known as Sig Sauer Inc. of Exeter, New Hampshire). Introduced in 2007, the hammer-fired P250 can be chambered in .22 Long Rifle, .380 ACP, 9×19mm Parabellum (9mm), .357 SIG, .40 S&W, and .45 ACP. The P250 chambered in 9mm was introduced to the North American market on November 7, 2007, followed by the .45 ACP compact model in February 2008 at the SHOT Show. The last of the models was introduced in late 2009.
In early 2014, the SIG P320 was introduced. This striker-fired descendant of the P250 continued the modular format and shares several of the same components including magazines and grip frames.
As of January 2017, the P250 was no longer listed online by SIG Sauer, except for a .22 Long Rifle version; no P250 was listed as of January 2018.
Design details.
The P250 has no manual external safeties. Instead, A firing pin block aids to prevent the weapon from accidental discharge.
The trigger is a self-decocking DAO trigger system with spurless and recessed hammer. The trigger system has a pull weight of about 45 N (4.6 kgf, 5.5 lbf)
The handguns are available with a dark colored Nitron slide surface finish, two tone finish, where the stainless steel slide has an untreated surface, and a diamond-plated finish.
Product evolution changes.
The grip module on the P250 Compact was changed in 2009. This change makes that the original and new style grip modules use different magazines. These old magazines are not compatible with new grip modules; the accessory rail was changed as well from a curved rail to a Picatinny rail.
The factory holsters of the original grip modules do not fit newer grip modules featuring Picatinny rails though the modular nature of the firearm allows the original grip modules to be easily swapped out with the new version inexpensively.
In 2012, SIG Sauer introduced a medium width version of the subcompact grip module with the Picatinny rail. The small width versions of the subcompact does not have this. Also introduced were exchange kits for a .380ACP and a .45ACP caliber subcompact version.
Discontinuation.
In the 2017 Sig Sauer catalog, the P250 was found under the rimfire category showing the .22 LR caliber as being available but mentioning that caliber exchange kits could be applied to convert the handgun to 9 x 19mm, .40 S&W, or .45 ACP calibers. As of January 2018, the P250 was no longer found on the Sig Sauer website.
