21 OD Green Question

[MPG1737]

I am aware that Glock has recently made upgrades to the locking block in the 21. My question is do the OD green frames have these new upgrades?

Any pics of an OD 21 frame would be appreciated.

If such an upgrade did take place you would have to go by serial number, not the color of the frame.

Perhaps if you contact Glock in Georgia they can shed some light on this issue.
