Glock grip plug for Gen 4 20/21 that works with backstraps?

[John Browning]

Does anybody know where I might be able to get a grip plug that:

- Works with Gen4 Glock 20/21
- Will allow for the installation of the backstraps

It seems like this should be simple, but it isn't. I've bought two different plugs, and they either are said to work with the 20/21 and don't, or they say they work with the back straps and don't.

I'm a clueless dolt. Help!

I don't believe anyone is making them yet.

Take a look at the pearce grip inserts for the Gen 4. They make it for the 21.

It is simple, forgo the grip plug. It serves no useful purpose and in fact closes off the way to pull the magazine out in the case of a malfunction.
