Glock frame compatability

[TLHelmer]

I have heard you can't use a gen 3 slide on a gen 4 frame. Is there anything you can do to make them campatible?

I have actually recently tried this. I found that the Gen 3 slide will fit the Gen 4 frame. BUT, after racking the slide a few times I noticed that the guide rod did not stay in the proper cut out recess of the barrel lug. My opinion, probably not a good idea to do. I have yet to see if there is anything that would allow this. I know Lone Wolf makes a conversion to make a Gen 3 17 slide fit on a Gen 4 19 frame.

I have a gen 3 Glock 20 slide, but no gen three frames. My frames are all gen 4's. It sounds like I should just pony up for a gen 3 frame.

Or sell me the 20 slide...

TLH, "SHurt" tried that when the Gen4 Glock 17 came out. At that time they had not released the Gen4 34, so he put his Gen3 34 slide on a Gen4 17 frame. His slide broke in half within a few hundred rounds. I wouldn't do it.

When (IF) we get our Gen4 21's in later this year, there will be a flooded market full of used G21SF's.

check out the polymer 80 frames. The older version was on sale for $50 last week, not sure what site. Im sure some digging would pull up results.
