Hi T H and welcome. CA compliant just means Beretta submitted and paid for vetting for this pistol to be certified and added to the CA Handgun Roster for sale in the state of CA. It will accept any standard and higher capacity magazine no issue. Cheers, stay safe and enjoy!

Yes, it will accept any compatible magazine, no matter the size. It's simply that it won't ship to CA with magazines that are larger than 10 rounds.

Yes, this will accept the 15rd magazine. CA compliant just means it comes with a 10rd mag and Beretta has paid the $200 extortion fee to have it put on the CA approved handgun roster.
Stay safe & have a great day!

Yes, a 15 round magazine will fit & function properly. CA compliant pistols/handguns have been put on the DOJ approved gun Roster after those gun Companies paid for the "Privilege" To be able to sell in CA.

Good evening to you!! Yes the Beretta 92 M9A1 will accept 15 round magazines even though it's CA compliant. CA compliant just means you can own it in Cally because it meets certain requirements. Hope this was helpful. Have a good rest of your day.
