I've seen posts about people mating a Glock 36 upper half to a Glock 30 receiver to make for a slim topped high capcity carry gun. I am EXTREMELY interested in this idea but I've seen some mixed info. I've read threads where it works flawlessly, and others where people have said it was a hoax and can never work. So, I'd like to hear from any who have done it how they work. But more so than that I want to know if a Glock 36 upper half will go right on a Glock 29 reciever and use Glock 30 mags. To me this would be a HELL of a combo. Slim single stack 45, high cap 45 with slim top, and Sub Compact 10mm, and with a barrel swap to the 10mm slide I can shoot 40 and 357sig, all in one. Are the ejectors the same on the 29/30/36? Or is there any internal part swaping that needs to go on in the frames? Most of what I see are Glock 30sf combos with the Glock 36. Is the SF the only one that will work like that or can I use a 30/29 frame? I'm really excited about this idea. My local dealer has a 29 on the shelf ready to buy. So I'd like to hear thoughts on this idea, and any experience from people that have done similar.
