There is many advantages to sticking to one round for your handgun needs. Instead of having to hunt for deals on three or four calibers, and stocking both practice and carry ammo for each can get to be a little wonky on both your budget and your gun cabinet shelf, a single caliber choice can streamline your life. The good thing about Glock is that they offer several platforms in the same calibers so that you can stick with the round you love no matter what you are carrying.

(From the top, the Glock 17, 19, and 26)

While there are several combinations out there for Glock lovers, such as .40S&W fans (the Glock 22, 23 and 27), .45ACP lovers (the Glock 21, 30, 36), I personally am more often than not a 9milly guy when it comes to Glocks (don\'t laugh we are sensitive) for my own reasons and to illustrate this article have chosen the platforms that use that caliber. However, with that in mind, you can substitute almost everything written here for the caliber of your particular choice.

The G17

This full sized G-wagon started it all for Gaston Glock, first being adopted by the Austrian Army as Pistole 80 some 34 years ago. Now in its fourth generation this 17-shot, 32-ounce loaded, 7.95-inch long pistol is the standard military issue sidearm for most NATO countries as well as being a big seller on the law enforcement and private gun market. If the 17+1 capacity isn\'t enough for your tastes, there are 33-round stick mags as well as 50-round drums out there to bring more love to the situation, so to speak. You would be hard pressed to find an all-around duty, range, or home defense pistol. Moving in calibers up, the .40 cal version of the 17 is the G22 while the .45ACP is the G21.

The G19

Just a tad bit smaller than its G17 big brother, the Glock 19 is a more compact design. Shaving off about a half inch and a few ounces, the gun is overall more concealable while still having a 15+1 capacity and the ability to accept G17 mags to boost that if wanted. This makes the G19 the choice for those who want the benefits of a full-sized gun with more concealability and carry ease. This is why the defacto gun of the NYPD, the largest police force in the US, is the G19 (although with a horrible NY1/NY2 trigger.) These guns have a huge fan club that includes NRA commentator Mr. Colin Noir and instructors Dave Spaulding, Larry Vickers, and Kelly McCann. Moving in calibers up, the .40 cal version of the G19 is the G23 while the .45ACP is the G30.

The G26

Going even smaller than the G19 is the subcompact Glock 26. This gun, first of the 1990s AWB-era \"Baby Glocks\" is about as groovy as it gets in tiny 9mm pistols that still have a decent magazine capacity. Weighing in at 26-ounces loaded and with a 6.41-inch overall length, the G26 still has a 10+1 capacity and can accept both mags for the G19 and G17 although of course they will hang out past the grip considerably. A bonus about this gun is that with its standard 10-shot capacity mags, its legal in many states (New York, California, etc.) that have ludicrous magazine capacity limits without having to get special compliant mags. Moving in calibers up, the .40 cal version of the 26 is the - while the .45ACP is the single stack G36.

Bonus: The G34

This gun is the tactical/practical 9mm from Glock. Set up as an out of the box competition piece, these guns are growing in popularity with IPSC and IDPA style shooters as well as in the 3-gun shooting world. While still capable of being used for defense if needed or CCW if desired, they are the perfect complement to older designs such as the G17L when it comes to ringing plates and punching holes in paper--and it\'s the same caliber as the G17, G19 and G26--, which can be easier on the ammo budget. Upsized caliber choices that are comparable are the G35 (.40S&W) and the new G41 (.45ACP).

As we noted, no matter if you are a 9, 40 or .45 guy (or gal), there is a Glock trifecta waiting for you and between the three (or four if you go practical/tactical), it\'s hard to find a situation you can\'t cover.
