Sig Sauer makes some beautiful guns. They’re also pretty expensive. Machining a metal frame costs much more than injecting polymer. With ATOS, Sig Sauer is improving inspection efficiency on parts that have small surfaces. The system captures full-field data, which cuts quality inspection time by 30 percent. Sig Sauer is now using ATOS for its most difficult parts.
Frame
Sig Sauer’s newest addition to their modular pistol line- a version of the military M17 currently being sold commercially- has garnered much attention. With competition from long-standing rimfire pistols and red-dot options like the ROMEO1, Sig’s P320 Compact has a tough act to follow.
The Sig P320’s external controls are simple, low-profile, and ambidextrous. It also boasts a 20-round capacity—something that’s hard to find in most semi-auto rimfire pistols. The Sig P320 Compact also offers a proprietary accessory rail up front compatible with a Romeo1 PRO, Deltapoint PRO, or RMR. It has a comfortable, aggressively textured grip module that’s easy to hold.
Slide
Sig Sauer handguns are a good choice for concealed carry, and they’re also great for self-defense. Whether you need more capacity or an improved trigger, there are Sig factory parts for sale. The slide on this pistol is not serialized, so you can change the caliber without changing the entire weapon. Sig offers kits for this purpose, called Caliber X-Change kits.
Barrels
Sig Sauer, known for double-action, single-action hammer-fired pistols, had only made a striker-fired polymer gun in the P320. It’s a gun embraced by police departments and large security companies worldwide.
They wanted to correct the major shortfalls of the early striker-fired guns (*cough* Glock *cough*). Hence, the XL version. It features a non-serialized firing component, so the slide and grip module can be changed with caliber change kits for common duty calibers like 9mm,40 S&W, and.357 Sig. Also, it has an accessory rail and a beefed-up steel guide rod.
Sights
A good choice of sights is a must for a defensive gun. Sig Sauer offers several options. It’s worth noting that the skeletonized striker assembly Sig introduced with the P320 was not there out of some German dedication to quality. It was necessary to fix a problem that caused the pistol to discharge when it wasn’t supposed to.
The actual portion of the gun considered a firearm is called the FCG, or fire control unit, and it’s also where you find the serial number. Sig has begun sharing technical drawings with carefully chosen companies to grow the well-fitting, reliable FCGs market.
Firing Pins
Sig Sauer is known (with a cringy exception or two) for making excellent handguns. Their entry into the striker-fired polymer pistol market with the p365 is a welcome sight that gives Glock’s double/single action hammer-fired guns a run for their money.
Upon release, the p365 had its fair share of issues, including problems with the night sights, triggers that didn’t go into the battery, and primer strikes that were too light. Sig Sauer responded to these concerns by upgrading the fire control unit.
Trigger
Sig Sauer’s flagship P320 is a popular choice among police departments, military shooters, and civilians who want a modular pistol that will last. It’s also a great gun to modify for aesthetics or performance upgrades. The heart of the weapon, the Fire Control Unit (FCU), is a stainless steel assembly that houses the trigger, disconnector trigger bar, and sear. It’s where you find the serial number.
Magazines
Sig Sauer’s magazines are well-regarded for their durability, reliability, and performance. Find the extended mags you need for your P320 or MPX in Black, Burnt Bronze, FDE, OD Green, or Vera Blue, and elevate your shooting experience at the range or in self-defense encounters.
It can fire many rounds through it without problems, including water-damaged steel-cased Tula ammo.
