Radian ramjet a failure - Radian Weapons Glock 19 9mm RAMJET Barrel w/ AFTERBURNER Compensator

I decided to upgrade my Glock 45 with a number of new parts, including the Radian Ramjet. From the first shots with it, the gun failed to load, jammed, or failed to eject. Frustrating? You bet. I put in a Radian adjustable compression spring set, putting in a 15 pound spring. Then I had light strikes. More frustrating when I learned this was a “Final Sale” item and can’t be returned. Think hard before ordering this replacement part. I’m selling mine as soon as I can. And I read that it is made to shoot 124 grain bullets. What nonsense is that? $400 and it won’t use 115 grain? Good luck, future purchasers. I had NONE.
