How to Choose the Right SIG Factory Parts for Your Firearm

The modularity of the Sig Sauer P320 makes it an excellent platform for customization and upgrades. For example, the type of ammunition you use can dramatically impact your shooting performance. Choose FMJ (full metal jacket) ammo to minimize recoil and maximize accuracy.


Unlike an AR-15, the pistol portion of a Sig Sauer doesn’t require an FFL license to purchase and install new grip modules. It makes it possible to swap out the gun’s grip module and trigger without altering the firearm. Triggers are available in various styles and weights, with many options of sig factory parts for sale catering to specific needs. For example, a competition shooter may prefer a light trigger pull, while a police officer or defensive pistol owner wants something much more rugged.

Two-stage triggers are also popular, and they’re known for having a short initial take-up before reaching a slightly heavier “wall” that must be overcome to fire the weapon. Be aware, however, that the extra crisp feel of a two-stage trigger requires more time in machining and tighter QC tolerances. It translates into higher costs. Additionally, using a super-light two-stage trigger in a defensive pistol could result in negligent discharges if the shooter is stressed or unprepared.


The barrel of any firearm is an essential component that impacts accuracy, durability, and overall quality. Its length, profile, and material all depend on its purpose. For example, if you intend to use your rifle for hunting or target shooting, a longer barrel provides greater stability and accuracy over long distances. Conversely, a shorter barrel is ideal for maneuvering tight spaces or protecting your home.

Barrels can be made from various materials, including stainless steel and chrome alloy. They also come in a range of profiles, from fluted to straight. The twist rate of a gun barrel is an important factor to consider, as too slow can compromise accuracy and too fast can cause bullets to fly out of control.


Sights are a key element of shooting a handgun. There are many types of sights to choose from, including combat style, fiber-optic and tritium. Combat sights are simple, with a wide front blade and rear notch. They are optimized for shooting large targets at distances up to 25 yards.

Some handguns come from the factory with combat sights mounted, while others have a milled slide to install a micro red-dot optic. A micro red dot is a sight that mounts on top of a pistol and projects a red or green dot that you use as an aiming point.

Fiber optic sights are popular upgrades that offer a clearer front and rear dot in low-lighting conditions. They come in various colors, and you can customize them with red and green fronts and dual rear dots. Most rear sights fit into a dovetail, a trapezoid-shaped notch that uses friction to hold the sight in place.


Whether you’re a competitive shooter, home defender, or just want to practice your shooting skills, you’ll need a magazine. While they don’t improve precision or speed like a new barrel or trigger, magazines are vital to firearms and must be able to work reliably. The follower connects to or rests on the spring inside your magazine tube. It is what pushes rounds upward for feeding, and it’s important to maintain proper alignment for reliable feed.

The base pad secures the follower and spring in the tube, and it’s also crucial to keep them seated properly. You’ll need to check it regularly for looseness and deterioration. Magazines are also subject to wear and tear, so regular cleaning and inspection is essential. Ensure you choose a magazine that’s easy to disassemble for cleaning and adheres to local laws and regulations regarding magazine capacity.
