Frankgon 4.... u are right. If u were to get the barrel for 9mm and magazine for it I'm sure it would work. I also did the same thing with my glock. 31 and just bought a 40 barrel and I am very impressed! Let me know if u do the 9mm conversion I would like to see that

I just picked up a Glock 31 about a month ago. I did not know it could be converted to .22 LR. I have the .40 cal barrel and I am gold that the Glock 17 magazines will fit and that with a 9mm conversin barrel, it becomes a Glock 17 9mm.
