This is an extended 33-round magazine for Glock pistols chambered in 9mm
Get the ultimate in high-capacity Glock firepower from the leader in aftermarket parts and accessories, SGM Tactical.
These aftermarket extended magazines will more than double the capacity of most Glock 9mm pistols, and they’re constructed from the same durable polymer as factory mags, with the same steel inserts and reinforced feed lips. Stainless upgraded springs ensure reliable long-term feeding through even the most extreme use cases.
Note: Extended magazines can come with especially stiff springs. Try loading half the listed capacity and leaving the magazine overnight to ensure easier loading in the future (or use a speedloader).
