Description

Sig Sauer P365 Threaded Barrel and Compensator Combo:

Upgrade your Sig Sauer P365, P365 SAS, or P365X with our premium Threaded Barrel and Compensator bundle, designed for enhanced performance and precision. The P365 Threaded Barrel boasts an improved feed ramp, ensuring smoother feeding of defensive ammunitions. Crafted with precision in the USA from certified 416R Stainless Steel, the barrel features a SAAMI Specifications Chamber and a 1/2x28 threaded design – the most common thread pitch for 9mm accessories.

The black nitride finish not only offers superior corrosion resistance but also provides a sleek, deep black color. The absence of a Loaded Chamber Indicator (LCI) prevents optic blowback and contamination, ensuring a closed chamber. This threaded barrel is specifically engineered for compatibility with Sig Sauer P365, P365 SAS, and P365X Models, fitting seamlessly into all P365 slides designed for a 3.1" barrel, with a 10:1 twist rate for optimal rifling in the 9mm caliber.

Complementing the threaded barrel, our P365 Compensator is CNC precision machined from aircraft-grade aluminum. The Type III Black Anodize Finish provides unmatched wear resistance, and its unique design includes one large top port and two 45-degree angled-up side ports on each side. With a total of five compensator ports, this accessory achieves a remarkable 30%-35% reduction in muzzle rise. For the ultimate reduction in felt recoil, pair it with the M*Carbo P365 Extra Power Recoil Spring Assembly – making it the ideal choice among P365 aftermarket accessories.

Great comp and barrel
review-star review-star review-star review-star review-star
As you can see I have an XL that barely qualifies as a Sig product anymore and a standard P365 with a few modifications. My XL with numerous modifications and the Strike Industries Quad Comp shoots like a dream for a handgun this size. However, the SI Quad Comp already has a stripped set screw that I would have to drill out if I ever want to remove the barrel, so never buying one of those again.

Now we have the new M*Carbo comp and barrel. The gold barrel with this comp is a visual stunner, especially with the slide locked to the rear. I will be taking it to the range tomorrow and I have no doubts I will notice a reduction in muzzle flip. Thank you for bringing a solid option to the market, because we really have not had any great options for comps until now!

Works great on XL with aftermarket barrel also.
Cut into a kydex holster so I will be carrying both 365 OG and an XL with this compensator
MCarbo claims they will sell compensator stand alone in the future.

What an awesome upgrade
review-star review-star review-star review-star review-star
I love the barrel design and overall quality. The compensator really blends in with my OEM P365 slide, the extra length is not an issue for me. Very reliable on the range, really helped with follow up shoot and reduce muzzle flip. Very good price point too, considered that some "competitors" are pricing their assembly at more than 300 dollars which is ridiculous to me.
