Has anyone tried using a Gen5 compatible Radian Ramjet in a Gen 6 Glock 45? I've seen a few guntoobers claim its possible, but wanted to see if anyone here had any first hand experience.

I've seen some Gen5 barrels be incompatible with the Gen6 platform....

There's a bunch being posted on Reddit.

It will work, but Glock and Radian seem to recommend against it because of the one difference between the Gen5 and Gen6 barrels; a new clearance cut in the back/bottom of the barrel.

The Gen6 barrels have that little scallop cut apparently to add more clearance so the part on the trigger bar that hits the striker block safety button can't rub against that spot on the barrel in the rare case where the slide is locked back AND the trigger is forced forward .

I have 3 Gen 5 afterburners in Gen 6 glocks (1 17, 2 19s)….i have experienced no issues as of yet…eta, I have probably close to 1000 rounds across the 2 19s..much less in the 17…hoping to add to that tomorrow
