Mine works great on a .270.
I shot a buddies .270 and mine back in forth on the same day. His not breaked, and it wasn’t even a comparison the recoil was way less. I haven’t put it through the paces in different shooting positions to tell if muzzle blast will be a downfall, but to match barrel...
Thats a good deal.

Works like a charm, all my OWB holsters have the ALS fork, so you just attach the plate side to this and your good to go.
