, some constructive feedback: the CFW9mmA bolts appear to be made to the same spec as the original .380 bolt. This includes the dimension of the breech face.
Since the .380 has a slightly smaller head diameter than the 9x19, the breech face is also of a smaller diameter.
This generally works fine with both cartridges, but I have run into instances where the case head of the 9mm would not fit onto the breech face. The same cartridges fired just fine with a 9mm spec bolt. Maybe my bolt is on the tight end of the tolerance range, and the ammo was on the wide end. Either way, it was not compatible.
You should consider machining the breech face like that of a 9mm bolt, as the slightly larger face diameter would still work fine for those who want to run .380 with their bolt.
