So, now, question for those of you who own a 1006 and a 4506 or 4506-1. (Or those who may know, regardless if they have them or not.) Are the top components (slide/barrel) interchangeable with the frames among these two calibers? This is an academic sort of question, as I am not am not nor have been a fan of the 10 mm, but like I said, I had a conversation that was left in the middle, so I thought to ask the knowledgeable! Thanx in advance friends!
