Bit late I know, but you can always get one…
“While Springfield offers a threaded barrel model Echelon, if you want to upgrade to a threaded barrel on your standard Echelon, Springfield Armory has you covered.
Currently, the company offers a 4.5” threaded barrel for the Echelon. It is a drop-in replacement, meaning that any gun owner can swap it out — where legally allowed — in the time it takes you to field strip the Echelon. No need to replace the recoil spring assembly or anything else.
Once installed, you can attach any muzzle device compatible with 9mm cartridges that uses 1/2” x 28 threads. For a lot of shooters, that muzzle device will be a suppressor. But, you can also add a compensator to mitigate muzzle flip during recoil. A comp can keep your gun flatter during rapid fire, making comps very appealing to competition shooters.”
