The Glock 21, chambered in the powerful .45 ACP cartridge, is a popular choice for many shooters. Its substantial size and capacity make it a formidable handgun, and the option to add an extended magazine further amplifies its capabilities. But before you jump in, let's delve into the details of using a Glock 21 with an extended magazine, exploring both the advantages and potential drawbacks.
Increased Capacity: The Primary Advantage
The most obvious benefit of using an extended magazine with your Glock 21 is the significant increase in ammunition capacity. Standard Glock 21 magazines typically hold 13 rounds. Extended magazines, however, can boost this capacity to 15, 17, or even more rounds, depending on the manufacturer and specific design. This added capacity provides a substantial advantage in self-defense situations or competitive shooting where rapid reloads are less desirable. The extra rounds offer a greater margin of safety and increase your ability to engage multiple threats effectively.
Considerations Beyond Capacity
While the increased capacity is a key selling point, several other factors must be considered when opting for an extended magazine:
1. Concealability: Size and Weight Matter
Extended magazines significantly increase the overall length and weight of the Glock 21. This can impact concealability, making it more challenging to carry comfortably in an inside-the-waistband (IWB) holster or other concealed carry methods. The added weight can also cause fatigue during prolonged use. If concealed carry is a priority, carefully evaluate whether the added capacity outweighs the reduced concealability.
2. Reliability: Magazine Quality is Crucial
Not all extended magazines are created equal. The quality of the magazine directly impacts the reliability of your firearm. Invest in reputable brands known for their robust construction and consistent feeding. Cheap or poorly made magazines can lead to malfunctions such as failure to feed or stovepipes, potentially compromising your safety in critical situations.
3. Legal Considerations: Magazine Capacity Restrictions
Before purchasing and using an extended magazine, be aware of any applicable laws and regulations in your area regarding magazine capacity. Many jurisdictions have restrictions on the number of rounds a magazine can hold, and violating these laws can result in significant legal consequences. Always check your local and state laws before acquiring any firearm accessories.
4. Ergonomics and Handling: Impact on Grip and Control
The extended length of the magazine might alter the balance and handling characteristics of the Glock 21. Some shooters find that an extended magazine improves their grip, while others report a slightly less comfortable hold. This is largely a matter of personal preference, and it's crucial to handle the pistol with an extended magazine before making a purchasing decision.
5. Maintenance: Cleaning and Lubrication
Extended magazines may require more frequent cleaning and lubrication than standard capacity magazines, as the increased number of components can potentially accumulate more debris. Proper maintenance is essential for ensuring the reliable function of your firearm and magazine.
Conclusion: Weighing the Pros and Cons
A Glock 21 with an extended magazine offers a significant advantage in terms of increased ammunition capacity, potentially improving your defensive capabilities or competitive performance. However, you must carefully weigh the potential drawbacks concerning concealability, weight, reliability, legality, and ergonomics. Thoroughly research reputable magazine manufacturers, understand local regulations, and test the firearm with an extended magazine to ensure it meets your specific needs and preferences. Responsible gun ownership involves a careful assessment of all factors before making any modifications to your firearm.
