Glock 21GEN4
$585.00
Greetings: I own a Gen 2 & a Gen 3 Glock 21. This insert fits well & looks great in my Gen 2. It fills the grip void nicely & adds a good although small additional storage compartment. Also make a nice slide ramp into the slide pocket. However, It is too large to install in my Gen 3. I do not recommend this particular one for a Gen 3. But I love it in my Gen 2. I probably misread the application table for this when I ordered it. I must be more diligent in reading the fine print on my next order.
