The description says these can be converted to fire live ammo with "the correct pieces replaced". What pieces are needed? A barrel obviously, probably extractor, recoil spring? locking insert?
Also do you know if these are these P229 or P229-1 mag/frame size?
Seems like it could be a fun project gun but dont want to get in too over my head
Should be just the barrel. They use a necked down 9mm to keep it from being able to load live ammo. Everything else should be the same as a standard gun.
