PRODUCT DETAILS
TECH SPECS:
Transform your SIG Sauer® P365 or P365X (3.1" slide) with the Radian AFTERBURNER™ + RAMJET™ combo—an ultra-efficient compensated barrel system engineered to deliver industry-leading recoil reduction, match-grade accuracy, and concealed-carry reliability.
This innovative combo extends your P365/P365X to the length of a P365XL, ensuring full compatibility with P365XL holsters without adding unnecessary weight or bulk.
Precision-Machined for Maximum Performance
The RAMJET™ barrel is crafted from premium 416R stainless steel, while the AFTERBURNER™ compensator is machined from hardened stainless steel—both enhanced with the advanced Radianite™ coating. This finish delivers extremely low friction, high hardness, and exceptional corrosion resistance, making erosion and wear from high-pressure gas virtually nonexistent.

Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.

Expensive but awesome
I have owned my P365 (Gen2) for many years and carried it as a secondary backup pistol during my federal agent days. Never had to use it in the line of duty, but it never failed me on the range during quarterly quals and other tactical drills. Great firearm, but like most micro sized pistol, harder to control and even harder on one’s hand…we only used 9mm +P 124 grain duty carry for all training. You really felt it at the end of the day, lol. I am retired now, but still use the same P365 as an EDC LEOSA CCW. I have made one modification after retirement by swapping out the old with a new grip module (Wilson Combat), but straddled the fence on getting a threaded barrel to add a compensator… Now, buying a good quality P365 threaded barrel and compensator would be the “cheaper” route, but you have to take in consideration with the Blue Commie States that outright banned threaded barrels. I live in a deep red state, but frequently visit a blue state across the river to visit extended family members. The Radian Afterburner Ramjet kit does definitely solve this issue…heck, for good measures, I only carry the 12 and 15 round magazines to satisfy the commie state laws with magazine capacity. Meh… I am a Radian fan and use several of their products for other firearm platforms like an AR15, but this Afterburner Ramjet kit blew me away. I did take it to the range the other day and it did not disappoint me at all. I was very hesitant to purchase it due to the cost, but after watching half dozen test review videos, I finally decided to pull the trigger…pun intended! I ran two types of 9mm, 115 and 124 grain FMJ brass casing of good quality factory ammunition. I started with the 115 grain using 12 and 17 round magazines. Zero misfeeds or ejection issues and I could definitely tell the 365 shot much flatter. Using the 124 grain with the same magazines felt a slightly better result. I even had a range buddy give it a try with the 115 and 124 grain ammo…he concurred with my assessment. Overall, I am not the least disappointed with this Radian compensator kit and have zero regrets. Just make sure you read the installation and maintenance instructions. This is too pricey to neglect. To paraphrase it, “rip the bandaid off quickly and walk it off”…the pricey “ouch factor” is only temporary.
