What is the difference between SIG M17 and M18?

The M18 is comparably compact, using the exact same frame as the M17 version yet its grip is smaller. Furthermore, the M17 has a shorter slide and a 3.9-inch barrel. The M17 is outfitted with a standard 17 round magazine along with two extended 21 round versions.

Built on Sig’s P320 platform and billed as the P320-M18, the pistol “is configured nearly identically to the U.S. military’s models,” Sig Sauer said in a press release, featuring black controls and a coyote-tan grip module, PVD finished slide, and ambidextrous manual safety.

What is a recoilless rifle?

A recoilless rifle, recoilless launcher or recoilless gun is a type of firearm designed to eject a countermass of some type to offset the recoil of firing. The system is called a recoilless rifle if it has a rifled barrel, and a recoilless gun if it is a smoothbore.

What is the difference between a recoilless and smoothbore?

Recoilless rifle. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are often called recoilless rifles.

What are the most common recoilless weapons?

Front-line recoilless weapons in the armies of modern industrialized nations are mostly man-portable devices such as the Carl Gustav, an 84 mm weapon.

How do recoilless anti-tank guns work?

Such large systems have mostly been replaced by guided anti-tank missiles in first-world armies. There are a number of principles under which a recoilless gun can operate, all involving the ejection of some kind of counter-mass from the rear of the gun tube to offset the force of the projectile being fired forward.
