H&K P30 and USP .40 Magblock   (10 Round Limiter for 13 Round Magazines)

This Magblock fits the H&K P30 and USP .40 magazines and will limit them to 10 rounds.  Easily installed in seconds under the magazine follower. It is held in place with tension alone.

In the case of the H&K P30 line, it did not exist before 2000, when the California high capacity ban went into effect. Presuming that only H&K magazines fit H&K  pistols, it would be impossible to own large-capacity P30 magazines before January 1, 2000 -- because none had yet been manufactured. Claiming to have owned such before this law went into effect is not going to stand up. Make sure you only use 10 round magazines in H&K P30 pistols since manufacture started in 2006.

- Simple install to make 10/13 H&K P30 magazines.
- Lightweight and will not interfere with magazine reliability.
- Made of heat resistant, reinforced polymer. 

FYI: The Universal Pistol Limiter cut to "6" in the indicator notch with a flush base works to limit this magazine to 10 rounds.
