ProMag DRMA73 50-Round Drum Magazine 9mm Sig Sauer P228 Black

The ProMag DRMA73 drum magazine transforms the Sig Sauer P228 into a high-capacity platform with 50 rounds of 9mm ammunition. This black polymer drum magazine eliminates frequent reloads during extended shooting sessions and competitive events.

What Makes This Different

Unlike standard 15-round magazines, this drum configuration provides over three times the ammunition capacity in a single loading. The polymer construction reduces weight compared to steel alternatives while maintaining structural integrity under repeated use. The spring-loaded mechanism feeds consistently through all 50 rounds without the stacking issues common in extended stick magazines.

Key Features

• 50-round capacity reduces reload frequency during range sessions and competition
• Black polymer construction offers durability with reduced weight
• Compatible with Sig Sauer P228 pistols and variants
• Spring-loaded feeding mechanism ensures reliable ammunition presentation
• Loading window allows visual confirmation of remaining rounds
• Reinforced feed lips prevent deformation under magazine spring pressure
• Drop-free design enables rapid magazine changes when needed

Range testing demonstrates consistent feeding through the entire 50-round capacity with standard 9mm ammunition weights from 115 to 147 grains. The drum configuration maintains balance better than extended stick magazines of comparable capacity. Competition shooters benefit from the reduced reload count during timed events, while recreational shooters enjoy extended shooting sessions without interruption.
