I've just come into a large quantity of 380 ammunition. I have a ruger lcp in 380, but shooting it for any extended range time is not a pleasant experience. I have a g19 Gen 5 in 9mm, as well as other 9s too. I was wondering if anyone ever swapped out the 9mm barrel for a 380 barrel? Is there even such a thing as a conversion barrel swapping a 9 into a 380? Thoughts? Ideas? Suggestions?
