Factory new 2022 SIG Neuhausen SG553 Pistol

The Swiss SIG SG553 also known as the “553” was launched in late 2007/early 2008 as an improvement to the previous compact 55X model the SIG SG552. The 553 returned the recoil spring back to the front of the firearm wrapping it around the piston like the original SIG 540 and 550 models. This change helped improve reliability as the SIG 552 had relocated the spring to the rear like that on a AK Kalashnikov design. The SIG SG553 also returned to the same original charging handle the 550 used.  The original 553 was an 8.25″ barrel but SIG also made a long barrel version with a 347mm or 13.7″ barrel known as the SG 553 LB. The LB variant has the grenade ring and can support a bayonet. The 553 like the 552 is arguably one of the favorite versions of the 55X family and is likely the most practical model for the modern era. The 553 and its many variants is used by militaries and law enforcement agencies around the world which includes and is not limited to: Argentine federal police, Brazilian Air Force, Special operations of the French Army, German GSG9 and GIGN, Malta’s Army, Polish GROM special forces, Serbian Anti Terrorist units, Venezuelan Marines, Swiss Army and police, the US FBI, DEA, and many SWAT teams, and most famously the Vatican City guard.
