Duration: 37:03

This review of the Sig P365 Fuse highlights its potential as a longer-barreled variant of the P365 platform. While the trigger and slide serrations are praised, significant issues with magazine reliability, particularly with the 21-round magazines, and extreme heat buildup on metal components were noted. A break-in period of approximately 256 rounds was required for 17-round magazines to achieve consistent cycling, with the 21-round magazines never fully functioning reliably in the test firearm.

Quick Summary

The Sig P365 Fuse requires a significant break-in period, with 17-round magazines becoming reliable around 256 rounds, while 21-round magazines never achieved full functionality. The firearm also experiences extreme heat buildup on metal components. However, it offers a smooth trigger and good accuracy, achieving a 2.25-inch group at 25 yards.

Frequently Asked Questions

What are the main reliability issues with the Sig P365 Fuse?

The Sig P365 Fuse experienced significant reliability issues, particularly with its 21-round magazines, which consistently failed to feed. The 17-round magazines required a break-in period of approximately 256 rounds before achieving reliable cycling. The firearm also exhibited extreme heat buildup on metal components.

How does the Sig P365 Fuse perform in terms of accuracy?

At 25 yards, the Sig P365 Fuse achieved a grouping of approximately 2.25 inches using a red dot optic and 115-grain remanufactured ammunition. This was considered a good performance for a stock production handgun, especially given the challenging conditions.

What is the recommended break-in period for the Sig P365 Fuse?

The review suggests a substantial break-in period for the Sig P365 Fuse. Reliable cycling with the 17-round magazines was not achieved until around 256 rounds were fired. The 21-round magazines never achieved full reliability during the testing period.

How does the Sig P365 Fuse's barrel length affect its performance?

The Sig P365 Fuse features a 4.3-inch barrel, which is longer than many P365 variants. This longer barrel contributed to higher muzzle velocities, averaging 1,140 feet per second with 115-grain ammunition, a notable increase compared to shorter-barreled models.
