CA CCW is not limited to 3 guns and is not limited to 10 rounds.
Many Sheriffs might not want to squeeze in another gun on the 3 lines provided; it can be done and was done on mine years ago when I carried up North.
I also carried a Glock 19 with hi-cap magazine. You can own the ones you had, just can't buy any more. That's why I bought some hi-cap mags for guns I didn't even own at the time, but knew I'd probably buy down the road, like my Glock 23.
IF I could put only 3 on a new CCW if & when (Puh-LEEZ happen!!!):
Kahr P45 in .45 ACP
Glock 23 in .40 S&W
S&W Model 49 in .38

There is a LOT of BS floating around about what CCW is and isn't in California. Don't make it any worse than it is by making stuff up.
