Most Helpful Positive Review really reduced felt recoil a lot
On my Sig P365 x-macro, felt recoil with the 3.7” barrel and no comp was very snappy. Almost uncomfortable and I was really wondering if I was going to keep the gun. I made the investment in a new slide and the Radian Ramjet. I’ve put about 200 rounds through it and it is a totally different gun. M...

Most Helpful Negative Review point of impact is terrible.
Sighted my EPS carry in with my OEM p365x barrel which is inline with my iron sights. Installed the Afterburner barrel and the POI was 6" to the left and 3" high. Sent back to Radian only to get JACKED around with their customer service people for over a month. Will never buy from Radian again.

Worth the price of admission

by Ragnarok, Verified Owner from MA, United States Written on June 1, 2026
Yes. Just do it. You need a ramjet.
I understand the price seems a bit high compared to other options, however, it's worth every penny. I have another brand comp, and it was annoying to install. Clocking it with the right washers, getting it just right, installing the red loctite and then torquing it down in a vice and waiting for the loctite to cure, hoping you actually lined it up correctly. It's not for everyone. This one here, you just drop the barrel in, slide on the comp, and put the screw in. It auto aligns AND you can take it off for those deep cleans of you firearm. I can't take the other one off. Ever. It's married to that slide for eternity. It might outlive us all.

A radian ramjet is def worth it though, it helps keep the pistol so flat and allows for much faster follow up shots. Do it. Do it now. Add to cart. Just do it. Enhance your shooting experience. Embrace your inner Wick.

“USED” Radian Ramjet w/ afterburner

by TheWheelLife Chad, Verified Owner from CA, United States Written on May 9, 2026
I purchased a “USED” Radian Ramjet & Afterburner combo for my Sig P365 (I haven’t used it with the firearm yet). I say “used” because I can’t even tell that the barrel and comp were used. They must have been a floor model or open box etc. because they both look new aside from the box being a bit scuffed up. The shipping was quick and the product was better than described. I’ll definitely be coming back to Optics Planet regularly for future purchases.
Pros:
  • fast shipping
  • decent price
Cons:
  • No clear explanation of what the used condition is/ looks like
Would recommend: Yes

radian ramjet

by trevor, Verified Owner from UT, United States Written on April 16, 2026
For the SIG X-Macro, this barrel comp is absolutely amazing. Anyone with a macro knows it’s a little snappy, well the Radian Ramjet Afterburner truly does reduce that snappy feel. Cannot recommend more to all my friends who have Macro handguns!!
Pros:
  • reduced barrel flip
Cons:
  • kind of pricey
Would recommend: Yes

high quality but not without issues

by fermundy, Verified Owner from IN, United States Written on March 27, 2026
It’s comes in a nice box. It’s silly it doesn’t come with any time of instructions for install other than a code to scan to take you to instructions online. It is very straight forward to install but they could at least include the torque spec for the screw on the box somewhere. Once on I noticed if racking to far forward there is a good chance of pinching a finger as it goes closed. Not normal but it’s possible. When shooting, it is quicker to get back on target. I’m not sure it’s enough of a difference to be worth almost 400 but it does make it possible to shoot faster due to less muzzle rise. I am happy with it. I just wish it didn’t cost quite so much. I know R&D costs too though and they clearly have good R&D

Installed the product and the muzzle flip was greatly reduced. I highly recommend it as one of the best upgrades I have done on my p365 x
