Now, as it is with pistols as popular as the Sig P365, aftermarket support is usually amazing, and today, we are proud to introduce the Strike Barrel for SIG SAUER P365. Upgrading the barrel of your pistol can have multiple advantages, like reduced weight, improved accuracy, and better appearance. So, if you're looking for a new barrel for your Sig P365, then the Strike Barrel is an excellent option.

The Strike Barrel for SIG SAUER P365 is Lighter

Being a polymer frame pistol, the P365 is already a very light pistol, weighing about 17.8 ounces. Most of the pistol's weight consists of the metal slide and barrel. Therefore, by installing the Strike Barrel, which is fluted to decrease weight, you can make your everyday carry pistol lighter, which is a huge plus.

The fluting also increases the barrel's surface area, allowing better heat dissipation and cooling if you ever need to fire a lot of rounds, perhaps at the range.

Stay Accurate

The Strike Barrel for the Sig P365 has a 1:10 twist rate for accuracy. It also has a reverse target crown to protect the rifling at the end of the barrel. So, the strike industry's barrel will stay accurate even after thousands and thousands of shots.

Durable Construction

With any firearm, the barrel needs to be durable, and the Strike Industries barrel for the Sig P365 is made from 416R stainless steel for extreme toughness. The barrel also has a black nitride coating, making it corrosion-resistant and more wear-resistant.

The barrel also has a SAAMI spec chamber, which means that everything is machined with high precision and craftsmanship.

Easy installation

Installing the strike barrel to your P365, or using it to complete a build is super easy. The barrel just drops into place and is perfectly made to fit in a Sig P365.
