Is it OK for me to swap my Glock 20 slide onto my 21 SF frame? I'm thinking yes, but just wanted to be sure.

One way to find out..... I know when I had a gen 4 and tried to put it on a gen sf lower, it didn’t fit .

It does fit, just haven't shot it. Both Gen 3.

Your good to go, as long as there bolth gen3. It will throw the10mm casings all over the place, but will work just fine.

The only difference in the 20/21 frame is the ejector.

It stands a chance of hurting you though. Don't do this without the proper conversion barrel.

One word- headspace

both 10mm and 40s&w headspace on the case mouth. If you load 40s&w in a 10mm chamber, the headspace will be way off. Will it cause a failure/kaboom? probably not... are you out of spec and totally accepting all liability? yes.
