Glock slide parts compatibility Gen 3 and Gen 4

I bought a used Gen 4 34 slide. It came with barrel and RSA but needs other internal parts. What are the differences between Gen 3 and Gen 4 upper parts kits. Can I get by with Gen 3 upk for range use?

Yep you can run gen3 parts in a gen4 slide no problem

My understanding is its the compatibility with the frame and slide that are the problem. I kinda want to know what you got your slide and barrel for, but it will just make me jealous.

Yep since Gen4s went to the dual RSA and I think they changed barrel lugs as well
When I had a G17 gen4 with a gen3 slide, I just needed an adapter for the recoil spring to fit properly between the frame and slide
That thing ran like a top, now I miss it

Does the same apply for Gen4 to Gen5?
was thinking of using a Gen5 slide on my gen4...

$200. If it had been a Gen 3 it would have been worth more.

Glock Parts Compatibility Chart

So, kinda new to Glocks and very new to Glock Talk, but I thought I might have something to add. I've been working on this parts compatibility chart for a couple days. So far, I've got all of the info from the Glock Parts Order Form. Is this something anyone would find helpful? If so, could...
