Will a LWD 45 ACP barrel that fits and works just fine in my G21 Gen 3 work in a G21 Gen 4 ?

Also will a LWD 20L longslide that I'm now using on a G20 SF fit and function on a G 21 Gen 4 frame ?

Yep & Nope!
The barrels are basically the same and switch between models easily.
The Gen4 frames utilize a large dual recoil spring. Their slides are different.
