FDEZ P365 FUSE 4.3” Slide
The FDEZ WERX P365 FUSE 4.3" Slide takes the P365 platform to the next level. Its extended recoil spring travel and wider spacing between porting work together to deliver smoother cycling and superior recoil control. Combined with the longer 4.3" barrel, this setup boosts ballistic velocity for greater accuracy, harder hits, and overall better shooting performance—making it the ultimate full-size upgrade for your P365.
Features
- Compatibility: Built around the Sig Sauer P365 Full-Size but will fit all P365 FCU’s and grip modules.
- Performance: Features patent-pending design and enhanced racking points front and rear for faster, more confident slide manipulation.
- Design: Deeper serrations and new racking points enhance slide manipulation and overall handling.
- Finish: Satin DLC Black
- Optics-Ready: Compatible with SIG‑LOC and RMSc footprints, including popular optics such as Romeo X Compact, Romeo Zero, 407K, 507K, EPS Carry, etc
- Holster Fit: Compatible with Macro holsters with open ends and Fuse holsters, although due to variations in holsters, adjustable retention holsters are recommended. Optional holsters available here.
Quality
- Every FDEZ WERX slide is machined in-house from US-sourced 416 stainless steel on HAAS VF2ss machines.
- Heat treated to RC 42–44 for strength, precision, and reliability.
- Made in the USA, patent pending, and backed by a lifetime warranty.
Notes
- The P365 Fuse Slide was designed to be used with 4.6” Flush & Crown, FDEZ Werx Ported, or Threaded barrels.
- Listing is for a stripped slide unless optional items are added.
- For best results, we recommend standard 124gr-147gr. While +P is compatible, it may reduce recoil control.
