Radian Weapons Afterburner / Ramjet - Glock 19 Barrel and Compensator

[Bayou]

To me the 34 seems so long and front heavy, strictly to me. Maybe, I was just wanting to mess around with one of these comps for a change up. I wouldn't put one of these on a 17 as that makes it a 34 length essentially but would do a 45. I like the 17 length and I have g4 17 but like the g5's better. That and I have carried a 17 for several years and have gotten use to it. Since I already have the 34, I'll just mess around with it to give it a fair shake. I wonder what the difference is between a comped 45 and 34 is as far as recoil, handling etc?

I think the Radian is slightly more effective as a comp than the Mayhem Syndicate, but the Mayhem is more reliable across a wider range of ammo, and doesn't need a lighter recoil spring.

Modern Warriors has quite a few of the Gen 5’s in stock. https://modernwarriors.com/product/r...ntra-lok-combo

I ordered one last evening. I’ll have to re-read this thread about recoil spring weights. I’m mechanically illiterate so after it arrives and I’ve played around with it a bit, I may have to come back and ask some stupid questions. Lookin’ at you, @JCN.

Happy to help anytime!

Some general philosophical thoughts:

1. A compensator and spring setup that "works" across a wide range of ammo isn't optimized for anything (it's an all-season tire).

2. Depending on your goal for the setup (gaming versus self defense), optimize the gun for that ammo and accept suboptimal in other settings. A summer tire isn't appropriate for snowy conditions, but it doesn't mean that a summer tire isn't the best for summer. Context matters.

3. Radian chamber is stepped so it needs more frequent brushing and cleaning than a normal Glock chamber. This also comes into play when talking about what springs will "work." A dirty chamber will have a harder time loading the next round so super weaker recoil spring will have a harder time doing this and can lead to FTRB issues. That's not an issue with the system, it's just something to keep in mind.

4. There is a limit to how weak you can go in a spring depending on weight of slide + optic and ammo power. If you have a regular striker spring you also have to overcome that with the recoil spring too. So if you use a fully tensioned Glock performance or Timney trigger it can tolerate less recoil spring.

For super gamer ammo, you'll probably need an 11 pound spring. There won't be much margin.

For most range ammo probably 13-15 pound spring will work. I favor 13#. This also assumes you don't do things like dragging thumbs on side of slide... if you do that, there's no combination that's going to overcome that extra resistance.

If you're gearing up for self defense type applications then 15# is probably the sweet spot. You'll have to use full power ammo.

NDZ makes inexpensive swappable recoil spring setups. Pro tip... you don't have to run the end retention screw and can then just make it an uncaptured setup for even quicker swaps.

I've run these rounds with my Afterburner/Ramjet for Gen 5. The main appeal for me was the lack of needing a threaded barrel as my state does not allow that. I'm not chasing maximum comp effectiveness and I have no interest in spring experiments, so these have all been with the factory spring and factory ammo:

S&B 115 FMJ
Winchester 115 FMJ
PMC 124 FMJ
Fed AE 124
Fed AE 147
Fed HST 124
Fed HST 124 +P
Fed HST 147
UMC 147 FMJ

Two pistols used:
Glock 45 with ACRO
Glock 19.5 with EPS

Every range trip involves at least two magazines worth of support hand only.

Zero issues of any kind across ~3000 rounds spread across those two pistols. So far I haven't cleaned them any more thoroughly than what has been my normal Glock cleaning for decades, i.e. pull a bore snake through the barrel and lube the normal lube points.

Are you iron sights or an optic? A heavier optic in addition to the comp may require hotter ammo or a lighter weight recoil spring.

• Glock 45 with ACRO P2
• Glock 19.5 with EPS

I am a pretty big/strong guy so maybe that helps.

On my Glock 45 with a Holosun 509t, the 15lb spring seemed to be the sweet spot. That said, I didn't have any issues with a full power spring, it just felt a bit over sprung to me. I run a lot of regular factory ammo, very little +p, but the +p ran OK too. My "gamer" loads are warm for that purpose, but don't hit full factory values.

Cool Ramjet build on a Nomad 9F frame.

Thinking about picking one up along with the recoil spring, are these legal in IDPA for carry optics?

Thanks
