Glock pistols are known for their ability to function flawlessly under a wide range of conditions, making them a trusted choice for professionals and civilians alike.
Ease of maintenance is another significant plus. The Glock 21’s design is relatively simple, which simplifies disassembly and cleaning. The availability of aftermarket parts and customization options provides shooters with extensive opportunities to personalize their pistol. Shooters can readily enhance their Glock 21 with improved sights, triggers, and various other components.
Potential Drawbacks of the Glock 21
One potential drawback to consider is the size of the grip. For individuals with smaller hands, the grip of the original Glock 21 may feel somewhat large, potentially making it difficult to achieve a comfortable and secure hold. This may lead to less-than-optimal control during shooting and longer reload times.
Overview of the Glock 21 SF (Short Frame)
The Glock 21 SF, or Short Frame, builds upon the solid foundation of the original Glock 21 while addressing a key ergonomic consideration. This model provides a modified grip, making it particularly suitable for shooters who find the standard Glock 21 grip too large.
Design and Features of the Glock 21 SF
The most notable feature of the Glock 21 SF is its “Short Frame” design. This modification significantly reduces the circumference of the grip compared to the original model. The grip is closer to the palm and allows for a more secure and comfortable hold.
The Glock 21 SF retains the core design elements of the original, including the polymer frame, the Safe Action system, and magazine compatibility. The magazine capacity remains identical.
The overall dimensions of the Glock 21 SF are slightly different than those of the standard model. These changes are primarily related to the grip. Standard sights are present and can be upgraded to improve target acquisition.
Advantages of the Glock 21 SF
The primary advantage of the Glock 21 SF is its improved ergonomics. The reduced grip size allows shooters with smaller hands to maintain a more secure and comfortable grip, leading to enhanced control and accuracy. This also facilitates quicker and more consistent trigger pulls.
The shorter grip design enhances the overall feel and the ease of use of the pistol. Some users find that the reduced grip also provides a slightly more balanced feel.
