Frequently Asked Questions
Is this magazine legal to purchase and use in California?
Yes. This ProMag drum magazine is specifically configured for California compliance, holding a maximum of 10 rounds of .40 S&W — within the state's magazine capacity limit. It is sold as a CA-blocked magazine and is legal for purchase and use in California under current regulations. Always verify local laws before purchasing any firearm accessory.
Will this magazine fit other Smith & Wesson pistols besides the SD40?
This magazine is designed and optimized specifically for the Smith & Wesson SD40 chambered in .40 S&W. While some S&W pistol variants may share similar dimensions, ProMag recommends verifying fit with your specific firearm model before use. Using an incompatible magazine may result in feeding failures or improper seating.
How do I maintain and store my ProMag drum magazine?
For best longevity, periodically disassemble and clean the magazine body, follower, and spring to remove carbon buildup and debris. Store the magazine unloaded in a cool, dry environment away from moisture and extreme temperatures. ProMag's heat-treated chrome silicon spring is designed to maintain tension over time, but rotating magazines in your regular-use rotation is always a good practice.
