A: Neil, this shotgun ships with (1) 10rd Magazine. Mossberg will be releasing optional 5, 10, 15, and 20 round capacity magazines which will be sold separately.

A: `1 -10 round magazine

A: Jonathan, I would go with this configuration, then you can mount virtually any 1 inch light you want. -- https://www.gggaz.com/mossberg-590-sling-and-flashlight-combo-mount.html

A: Yes Jonathan, it is very possible. Here is one possible 300 lumens combination that might help you: https://www.amazon.com/Mossberg-Gauge-Mount-Single-Mount/dp/B0734DB7K2

A: It is certainly possible to mount a light, which light in particular is up to you as there should be a mounting solution for almost anything. As James G posted, you can get mounts for the magazine tube and then any picatinny rail flashlight mount would work. I would add that there are also picatinny rail forends you can buy that would allow you to mount a light to the pump handle if you have a preference, one pro for that would be the light is right by your hand so you can manipulate the switch with ease. Surefire also makes a forend with an integrated light; however, those are very pricey (close to $400).

A: There are many clamp on rails that will fit the magazine tube https://www.amazon.com/Streamlight-Mag-Tube-Rail-SuperTac/dp/B0028LXG5A

A: Hi Stephen, yes sir, this is CA compliant. Pump action shotguns do not have the same restrictions as semi-auto's do. Stay safe & have a great day!

A: Hi Stephen and welcome. Yes Sir, this Pump Action is 100% CA legal. A Semi-Auto would be restricted due to the detachable magazine. Details under "Shotguns" here: https://www.budsgunshop.com/feeds/state_reg/california_restrictions.pdf -------- Cheers and stay safe!
