I am very curious if the 9mm barrel will drop in and function in the 40.



Do ya mind doing a test to see if it will work?

You will need a conversion barrel! Many of us are waiting for it to come out. Just a matter of time!





9mm barrel is sloppy in the slide. Need O.D. that equals the 40 bar. but with a 9mm chambering in it!

I tried it. The barrel fits fine, as I expected. However, I tried manually cycling a few rounds through it. Extraction of the 9mm brass using the .40 slide and 9mm barrel was iffy at best. I doubt it would work very well, if at all, in actual firing. I would say you need a complete top end, not just a barrel. I have interchanged top ends in 9mm and .40 without any problems. My understanding is that the 9mm and .40 frames are exactly the same.
