It is comically easy to modify or manufacture magazines. A lot of 10 round magazines are just standard mags with a spacer. I used to live in California. Every time I went shooting in Nevada, I'd remove the spacers, turning my 10 round magazines into 50 round mags, then change them back before I returned. If you look at photos of confiscated guns in California, very few have 10 round magazines. Scrolling through SFPD's twitter, I can only find photos of illegal guns with illegal magazines.[1][2][3] The second photo is of a Polymer80, which is a pistol you can make at home using a dremel and a hand drill. They're compatible with Glock parts and quite reliable. These laws do nothing to reduce violent crime. The main effect is to annoy law-abiding gun owners. When I moved out of California, it took me maybe 30 minutes to undo all the CA-specific modifications on my guns. 1. https://twitter.com/SFPD/status/1511846273644589058 https://twitter.com/SFPD/status/1511846273644589058 2. https://twitter.com/SFPD/status/1509268939292872707 https://twitter.com/SFPD/status/1509268939292872707 3. https://twitter.com/SFPD/status/1506372044492972035 https://twitter.com/SFPD/status/1506372044492972035
