Got my new G21 Gen4 yesterday...lovely weapon, but I want to get a G20 slide for it so I can get 10MM , .40, and .357 sig barrels. I cannot find Gen4 G20 slides anywhere...and the aftermarket hasn't started making them yet. I find that it is possible to use a Gen3 slide on a Gen4 frame...except the dust cover doesn't quite match up (pic below). So the logical question...does anyone make a spacer to fill the gap? As a side question, does anyone know of a site selling Gen4 G20 15rd mags (with the slot for left handed mag release)?
You may want to call this company and ask them your questions.
If anyone would know they should. I have used them for many items over the years.
