Ergonomics

Frame

When it comes to frames, the P320 pistol is fitted with a stainless steel frame and modular polymer grip, while the Glock 19 is built with the manufacturer’s usual high-strength nylon-based polymer frame.

The Glock 19 is equipped with customizable backstraps, which allow you to change the grip to fit your hand size. The P320 Compact does not have this feature, though you are able to change the entire grip module if desired.

Slide & Barrel

The Sig P320 has a carbon steel barrel and Nitron finished stainless steel slide, increasing its durability and helping to protect the gun from scratches and corrosion.

Many of the newer Gen 5 Glocks, including the Glock 19, have slides built with a durable nDLC finish designed to protect the pistol from scratches and corrosion. They also come equipped with the Glock Marksman Barrel, which is designed with enhanced barrel rifling for better accuracy.

In terms of accuracy, you may find the Glock Marksman Barrel is just what you’ve been looking for. On the other hand, the Sig P320 is also known for its out-of-the-box accuracy with any type of ammo.

Sights

It’s no contest: the Sig P320 is the clear winner when it comes to sights.

The P320 comes with your choice of steel 3-dot contrast sights or SIGLITE Night Sights. The Glock 19, on the other hand, comes equipped with Glock’s standard plastic sights.

Though the Glock doesn’t come with the same quality of sights out of the box as the Sig, both pistols are designed so they can easily be upgraded with sights of your choice.

Optics

Though neither base-model pistol comes optics-ready, both the Glock 19 and the Sig P320 are available in an optics-ready variation.

So, if you’re interested in utilizing optics or accessories, you may want to consider either the Glock 19 Gen5 MOS or the Sig Sauer P320 RXP XCOMPACT.

Controls

Safety

While neither gun comes standard with a manual safety, both have robust safety systems to ensure peace of mind.

The Glock 19 features the Safe Action System comprised of three independent mechanical safeties that disengage as the trigger is pulled and reengage as it is released. The Safe Action System does provide protection if the firearm is dropped.

The Sig P320, on the other hand, has striker safety and a disconnect safety in addition to a 3-point takedown safety that allows you to disassemble your pistol without pulling the trigger.

Trigger

The Glock 19 is designed with a 2.80” trigger distance and an approximate 5.6-pound trigger pull, while the Sig P320’s curved trigger has a clean, striker-fired trigger pull weight of around 7.5 pounds.
