Can a P365 be made to compete with a 2011? Kiral Defense 6511X

Duration: 13:58

This video explores the potential of a heavily modified Sig Sauer P365, featuring a Kyro Defense 6511X grip and an Fdez XXL slide with ports and a comp, to compete with 2011 pistols. Testing reveals significant recoil reduction and improved handling due to the added mass and aggressive grip, though a notable velocity loss is observed with the ported slide. While accuracy with the modified slide is compromised, the overall package offers a surprisingly stable shooting experience for a compact platform.

Quick Summary

A heavily modified Sig P365, featuring a Kyro Defense 6511X grip and an Fdez XXL ported slide, can achieve significantly reduced recoil and improved handling, approaching 2011 pistol performance. However, this modification can result in a notable loss of muzzle velocity and potentially compromise accuracy compared to a standard slide.

Frequently Asked Questions

Can a Sig P365 be modified to shoot like a 2011?

Yes, with significant modifications like an extended grip module (e.g., Kyro Defense 6511X) and an aftermarket slide (e.g., Fdez XXL), a P365 can achieve much of the recoil mitigation and handling characteristics of a 2011 pistol, though some precision may be sacrificed.

What is the impact of ported slides on P365 velocity?

Porting and compensating a P365 slide, such as the Fdez XXL, can lead to a noticeable reduction in muzzle velocity. Tests showed an approximate loss of 100 feet per second with 115-grain ammunition compared to a standard slide.

How does an aggressive grip texture affect P365 handling?

Extremely aggressive grip textures, like silicon carbide, provide exceptional purchase and prevent the firearm from shifting in the hand during recoil. This significantly enhances control, though it requires careful handling to avoid discomfort.

Is a modified P365 competitive with a 2011 in shooting sports?

A heavily modified P365 can be viable for certain competition divisions like Carry Optics, offering improved stability. However, for maximum performance, dedicated 2011s or other meta-platform guns may still hold an edge due to their inherent design and trigger quality.
