Faxon Firearms Exos-514 Ffpacompdsmp01 Exos514 Comp M&P

The Faxon Firearms Exos-514 compensator is a 9mm muzzle device purpose-built for Smith & Wesson M&P pistols. If you're running a full-size M&P 1.0 with a 4.25" barrel or stepping up to the M&P 2.0 platform, this comp is engineered to reduce muzzle climb and felt recoil during rapid fire—crucial for competition shooters, tactical training, and anyone serious about follow-up shot accuracy. The Exos-514 uses a single-chamber design with uniquely angled front ports that work differently than traditional side-porting: gas deflects upward as well as sideways, which means less vertical muzzle movement and more predictable shot-to-shot consistency.

Built from 6061 aluminum with a black anodized finish, the Exos-514 is a tough, lightweight addition to your M&P. The design seats flush with your slide when used with Faxon barrels, or with any aftermarket barrel that protrudes 0.600" or less. Installation is straightforward—you get thread locker, two 6-32 set screws, and a 1/16" Allen wrench in the box—but keep in mind that running a compensator can shift your pistol's timing and may require tweaks to lubrication and ammo selection depending on your specific gun and load.

Compatibility is confirmed for the M&P 1.0 Full-Size 4.25" and reasonably expected for the M&P 2.0 Full-Size 4.25" and Compact 4" models, though fitment with other barrels or M&P generations isn't guaranteed. Always verify your exact setup before purchase, and be aware that comps add velocity signatures and sound—not legal in all jurisdictions or ranges.

Frequently Asked Questions

Will this compensator work on my S&W M&P?

The Exos-514 is confirmed compatible with the M&P 1.0 Full-Size 4.25" barrel. It's reasonably expected to fit the M&P 2.0 Full-Size 4.25" and M&P 2.0 Compact 4" models, but fitment with other M&P generations or non-standard barrels isn't guaranteed. If your barrel protrudes 0.600" or less, you're more likely to get a flush fit. Always verify compatibility with your exact model before ordering.

What's included in the box?

The Exos-514 ships complete with thread locker, two 6-32 set screws for securing the device, and a 1/16" Allen wrench for installation. You'll have everything needed for assembly, though you may want a 1/2x28 thread-chasing tool if you're working with an older or heavily used barrel.

Will a compensator change how my M&P runs?

Yes—running a compensator can affect your pistol's timing and cycling. Depending on your gun, you may need to adjust lubrication, switch ammunition, or modify your recoil spring. Start with the load and lube setup your gun likes, then test and adjust as needed. Not all M&Ps respond identically to a comp, so patience during break-in is worthwhile.

Is this legal where I shoot?

Compensators increase muzzle velocity signatures and sound, and they're restricted or prohibited at many ranges and in some jurisdictions. Always check your local range rules and local laws before purchase and installation.
