$38.50 each. I just ordered 5 of them. For my G20, that extends the mags to 20 rounds, or 21 on 1st gen G20 mags.
20 or 21 rounds of 10 MM seems like too much, until you get yourself in a situation where 15 just is not enough. Knock on wood, I never need the extra rounds, or even one round!
I can tell you this much, Obama sure is a good sporting goods salesman.
I also ordered this, just in case: (bottom two pics)

Why?
