Glock 20: The Original 10mm Contender
The Glock 20, introduced in 1990, was specifically designed for the powerful 10mm Auto cartridge. This combination has made it a popular choice among hunters, outdoorsmen, and those in need of a large-caliber handgun for self-defense or duty use. Before we examine the Glock 20 SF, let’s first take a closer look at some of the key features and specifications of the original Glock 20.

- Weight: The Glock 20 is a fairly heavy handgun, and when loaded, it can become fatiguing to carry for extended periods.
- Availability of 10mm ammo: Although it has become more popular in recent years, 10mm Auto ammunition can still be harder to find than other handgun calibers like 9mm or .40 S&W, which might hinder training and practice opportunities for some shooters.
Glock 20 SF: A More Ergonomic Alternative
Introduced in 2007, the Glock 20 SF (Short Frame) was an answer to the grip size concerns raised by many users of the original Glock 20. Although the changes may appear subtle at first glance, the reduction in dimensions makes a significant impact on how the gun feels and handles in the hands of the shooter. Now, let’s look at the key features and specifications of the Glock 20 SF and what makes it stand out.

- Not a complete overhaul: While the SF model addresses some of the ergonomic concerns of the original Glock 20, it might not represent enough of a departure for some users who still find the design uncomfortable or unwieldy.
- Ammunition availability: Just like the original Glock 20, finding 10mm Auto ammunition can still be a challenge for those wanting to carry, train, or shoot with either of these pistols regularly.
Comparing the Glock 20 and Glock 20 SF
Now that we’ve explored both pistols in detail, it should be clear that the main difference between the two lies in the grip dimensions. If you have smaller hands or find the original Glock 20’s grip uncomfortable or difficult to manage, the Glock 20 SF might be a more suitable option for you. However, it is essential to note that the basic construction, performance, and most other attributes of these guns remain identical.
Ultimately, the decision between the two models should come down to your personal preference and how comfortable you are shooting each pistol. It is highly recommended that you try both out for yourself at a local gun range or firearm store to determine which one is the right fit for you. Regardless of which model you choose, you’re likely to be satisfied with the proven performance and reliability that the Glock brand has become synonymous with over the years.
