If I sound illogical or crazy just let me know, and I'm serious, I will not get offended at all. So here goes, I recently purchased va SA 911 9mm and I really want a threaded barrel for it but they don't exist. However threaded barrels are sold for the Sig P938, and SA pretty much copied Sig design for the 911 and they look very similar. Now my question is, since the guns are so similar can I order can order the P938 threaded barrel and have a competent gunsmith modify it to fit and function properly in my 911? Like I said if I sound illogical let me know.
