Radian Ramjet fit guide

Short answer: Buy the Radian Afterburner Ramjet by the model and generation in the title. A Glock 19 Gen 5 kit is not a Gen 4 kit and not a Gen 6 kit. A 17 kit is not a 19 kit. The 48 kit is the 48, not a 43 or 43X. P365 3.1 and P365XL 3.7 are different barrels.
Match the title: Glock 19 Gen 3, Gen 4, and Gen 5 are three kits. Glock 17 Gen 5 is its own kit. The Glock 48 listing says Glock 48. Glock 26, 43, and 43X kits are separate parts. Sig P365 is the 3.1 barrel. P365XL is the 3.7 barrel. The Ruger RXM listing says a 4.0 barrel. Other finishes of the same model are the same fit. The Gen 6 listing names Glock 19 and 45. A Gen 5 kit is not that part.
What the listings say: These are a fluted barrel plus a compensator, not a thread-on device. The mount is called INTRA-LOK: a tapered pin in a V-groove that times the comp. The Glock 19, P365, P365XL, and RXM listings describe the Afterburner as .47 inches long and quote up to 44% recoil reduction with 115g ammunition. Those figures are the listing text.
Holsters and springs: Those listings say the angled front faces aid holstering. Added length can still stop in a closed holster. Test the factory recoil spring with your ammo: lock back on empty, ejection, and return to battery. Glock spring weights by generation: recoil spring weights.

Questions
Does a Gen 5 Ramjet fit a Gen 6 Glock 19?
No. Buy the kit titled for Gen 6. The Gen 6 listing names Glock 19 and 45. A Gen 5 kit is a different part.
Will a Ramjet clear a closed holster?
Added length can stop in a closed holster. The listings say the angled front faces aid holstering. Check the shell you own.
Do I need a lighter recoil spring?
Test the factory spring with your ammo. Confirm lock back on empty, ejection, and return to battery.
