I've tried searching all over Google regarding this question and came up dry. I'm purchasing a Gen2 Glock 19 today and I'd like to purchase a threaded barrel for it. Can I buy a new threaded barrel for the g19 and it would work or is there a specific barrel I should be looking at. I came across one forum stating that gen4 and new gen 3 barrels work with gen 4. Older gen 3 are for older gen 3, and gen 2 for gen 2. So what's my best option for acquiring a threaded barrel for my pre94 gen 2 Glock 19. Links to products would be appreciated if they're available. Thank you!!
