Jiwan, Here are the 4800+ firearms BUDs list that are CA compliant. Very few semi=auto handguns available-----------budsgunshop.com/search.php/type/Firearms/exclusive/ca

Unfortunately right now there are not many CA compliant semi autos in stock it looks like as all they have at the moment is browning .22 LR semi automatic pistols, here is a link to all the semi auto ca pistols currently in stock at buds
budsgunshop.com/search.php/exclusive/ca/other/in_stock/type/Pistols />Out of those I'd go with
Browning Buck Mark .22 LR Plus/Matte Blue 5.5" Barrel & Rosew
Buds item number 45434
I would say either of these revolvers would make fine a choice if your looking for a personal/home defense weapon
Ruger GP100 .357 Mag 4.2" 7 Round Fiber Optic Front Sight
Buds item number 48995
budsgunshop.com/product_info.php/products_id/48995 />Or
Smith & Wesson 610 10mm 4" Stainless Steel
Buds item number 415007184
budsgunshop.com/product_info.php/products_id/415007184 />Here is a link to every handgun currently in stock that's on CA DOJ roster.

Good luck and stay safe

Someone who seems to care as little as you should probably not have a real pistol.

Jiwan, you may have to go outside of Buds as Semi-Auto handguns legal for CA are slim pickings. There are a few revolvers : -- budsgunshop.com/search.php/type/Firearms_Handguns/exclusive/ca

Hi,
This page contains all CA Compliant handguns on Buds (budsgunshop.com/search.php/type/Handguns/exclusive/ca/page/1). Glock and M&P pistols in 9mm are generally recommended as they have large aftermarket support and well received. I hope this helps.
