1SG from United States, GA Public Profile

I bought my CAA Gen 2 Micro Conversion Kit for Glock 20/21 a week ago and it doesn't work with my G21 Gen3. This item is marked as Final Sale "Final Sale items are not eligible for returns or exchanges." So I'm going to have to modify it to use it. It wouldn't allow the pistol to fit properly into the sliding chamber of the kit causing the lower locking latch to NOT close. The charging handles would not arm the weapon as well with or without the lower locking latch closed. The funny thing is, I have the Gen 1 Micro Conversion Kit for my G17 and it works absolutely fine. So I'm not sure why this one is defective from OP. I'm going to contact the CAA MCK Company to see what they can do before modifying it myself. I hope you have better luck than me.

NOTE:I should have known something was wrong when I saw the "Final Sale items are not eligible for returns or exchanges." I was too excited about the pricing.
