It appears that the would be assassin of a Supreme Court justice bought his Glock in California. It that be true, then it came with limited-capacity 10-round magazines—<sarc>making it so much less dangerous.</sarc>

Never pick a fight with a man who buys pixels by the terabyte.
Because no one in the world could figure out how to modify the follower in a magazine to hold more than 10 rounds. I think that’s the first think I looked at on my .22 pistol where the mag has this ridiculously large follower installed to make it a 10-round mag. These people are insane.
Easier to just purchase standard magazines on the way. Not a controlled item in Free America so no checks of any kind..
