Hello, I want to buy a G27 and along with it a conversion barrel to 9MM. I am considering the LoneWolf offering but I have a couple of questions. --Is the rifling of the barrel the same as the Glock OEM conversion barrel? From what I read it seems to be different.... but I do not know the implications. --If not what are the advantages/disadvantages? --Is there a requirement for swapping out any other components to make the conversion. I have a G22 so what to be able to carry the same caliber if I choose or do target practice with the 9MM and determine if the recoil characteristics are so much better that I would go with the 9MM as summer carry or a BUG.
