Glock G42: A Remarkable Handgun

By Bob Campbell published on in Ammunition, Firearms, Reviews

For most of my life I have carried what some refer to as big guns. The Chief’s Special is a backup. The Commander .45 is a carry gun. And I am familiar with practically every light pistol made in the past century, from the Harrington and Richardson SLP to the Walther PP Super. Some work better than others. Very few have service-gun reliability.

The very nice, slick SIG P230 is a great handgun, and there are not many others I trust.

GLOCK 42 Right Profile

The GLOCK’s well-designed cocking serrations are easy to grasp.

And frankly, compared to the current crop of compact 9mm handguns, the P230 is not that small.

Enter the Glock G42, a long-awaited and much heralded pistol. The GLOCK G42 is a slim, light and reliable .380 ACP pistol. To its credit, Glock did not attempt to build a pistol that stuffs 10 rounds into the frame.

There really is not anything quite like it.

The Glock G42 bears a resemblance to the Generation 4 Glock , with the same grip texture and magazine release, although it does not have the light rail or interchangeable back strap.

Features of the GLOCK G42

The pistol is a fresh design, building on proven Glock  principles. The G42 is a 6-plus-1 capacity pistol, thin, very thin, with a 0.95-inch frame and 0.825-inch slide. The pistol is only 4.25 inches tall and just short of 6 inches long and weighs 12 ounces unloaded. While some pistols pretend to be pocket pistols, the Glock G42 .380 ACP is a true pocket pistol.

An important difference between the Glock 42 and the other .380 pistols is that the G42 is not a blowback pistol. In these handguns, the slide blows to the rear off of a fixed barrel. The locked breech is the stronger system and is seldom used in pistols of this size and weight. An advantage of that operating mechanism is recoil and pressure are controlled more efficiently.

The pistol features dual recoil springs in the modern spring-within-a-spring Glock design. Another advantage of locked-breech design is that handloaders may load the cartridge a bit hotter. I do not wish to contribute to the delinquency of handloaders, but another locked breech .380 ACP pistol, once very popular, was the Star S Model.This was a strong locked-breech with which I experimented a few decades ago. However, .380 ACP ammunition has improved somewhat in the past decade, as I discovered while testing the G42.

GLOCK 42 profile view

The G42 is small enough to carry comfortably but large enough for proper hand purchase.

The pistol features a six-round magazine and comes with two magazines (supplying a pistol with only one magazine is ridiculous). The pistol’s trigger action, sights and appearance are typical GLOCK, and it feels good in the hand. I have never thought the GLOCK has a natural point; this pistol is an exception. Another exception is that it is made in America. Imports, exports and tariffs are heady political discussions, and the bottom line is that Glock  has given a lot of good folks in Georgia honest work. I like that.

The pistol operates in the same way as every other Glock . When you rack the slide, the trigger partially cocks, or is “prepped” in Glock parlance. The striker partially draws to the rear, and a long press of the trigger completes the job of cocking and releasing the striker, resulting in a 6-pound trigger compression. In my experience, the Glock trigger action may run from 5 to 6 pounds. The G42, however, feels lighter, which may be a result of the leverage of the small handgun. The RCBS registering trigger compression gauge does not lie.

The mechanics of the pistol are similar to the full-size Glock , with slight differences, such as the springs in the takedown lever and the slide stop’s design. That is understandable when the pistol is downsized to this degree.

Firing the Glock G42

GLOCK 42 Magazines, Loaded

GLOCK G42 magazines hold 6 rounds of .380 ACP ammunition.

After initial familiarization, I fired the G42. I had on hand no less than six types of .380 ACP ammunition. Considering the present ammunition shortage, that is a goodly amount.

I had:

  • Three types from Fiocchi, one ball load and one using a standard JHP.
  • The Extrema line, using the XTP bullet.
  • The CORBON DPX load, using the all-copper X bullet.
  • The new Winchester Defense load, using the PDX bullet.
  • The Hornady Critical Defense loading.

I will remove the suspense—there were no failures to feed, chamber, fire or eject.

The G42 is very comfortable to fire. In my experience, small guns are less reliable than larger pistols. There is simply a more crowded platform that invites the fingers to interfere with the slide stop or trigger. The Glock  platform is businesslike and manageable, even in this small pistol, and the G42 is never uncomfortable to fire. There was little difference between firing the hottest loads and the mildest ones. There was more push and more muzzle flip with the CORBON loading, yet nothing uncomfortable.

In my mind, that is the rationale for the light .380 ACP pistol; it is lighter than the 9mm and should kick less. I do not mind mastering a hard-kicking big bore, although when carrying a light caliber, the recoil should be light as well. The bottom line is that the pistol should be reliable. The Glock G42 meets all of those criteria.

Ammunition Performance

GLOCK 42, CORBON DPX Ammunition and ProChrono

Velocity results with CORBON were good.

Ammunition performance was an eye opener. As an example, the CORBON 80-grain DPX load averaged 1070 fps. That is impressive because the G42 barrel is a stubby 3.25 inches. The CORBON loading breaks right at 200-foot-pounds of energy. The heavier bullet loads exhibited respectable velocity. A defense load must demonstrate a balance between expansion and penetration. None of those loads fundamentally change my mind about the .380 ACP, and they do make the most of the caliber.

I found it interesting that the G42 is accurate enough to invite recreational shooting. Small sticks and the usual range bric-a-brac were easily addressed to 15 yards. It is accurate enough to serve for pests and reptiles at a reasonable range. The G42 is fast from concealed carry and comes on target quickly. I find it the best-handling and most accurate .380 ACP in my recent experience.

Glock has a winner in the G42.

    Seems like a pretty solid gun. Which glock is the best glock for everyday carry?

    Mine was the April 2015 edition. It has run 100% with everything including all the cheap Russian stuff which sometimes has hard primers and will not work in other 380s. I since went with the Glock 43 part-time and find the 9mm version is far more accurate and it too shoots everyhing you put in it. I bought my first Glock 19 in July 1990 and really don’t like plastic guns…I like 1911s and top quality wheel guns, that being said, the 3 9mm Glocks I own have never, ever had a failure of any kind whatsoever. I dont shoot reloads or cast in Glocks polygonal barrels so that may help. But you you realize I have had one of these since 1990 and never had a failure, that is pretty remarkable.

    I bought my G42 September 2015 and had issues with ejection. It was manufactured June 2015 with the latest updates at that time. I sent it back to Glockenspiel in January 2016 and they replaced the ejector and upgraded all 5 of my magazines to version 3 for free, even the ones I bought elsewhere. It has worked flawlessly ever since. Flat tipped Winchester was the worst before the fixes but even they work now.

    I purchased a 42 and had the same problem with mine. I have always carried hollow points in my weapon, but the first time I took mine to the range, the hole in the tip of the round hung-up. The FMJs work perfectly so that is what I am loaded with. not happy about it, but it is what it is. I love my 42 as it is small, light, and unnoticeable. Sort of wish I had gotten the 43 as it is almost the exact size, but 9mm.

      Mine runs Hornady and Fiocchi 90 gr. XTP’s with no problem. Of course, no problem with the FMJ practice rounds, either. You just gotta hold the gun with authority. Good groups at 25 yards; good enough to put the bad guy down. Had a problem my 1st time shooting, but learned through the net you just have to hold it tight. As fast or slow I can pull the trigger, no problems anymore. Gun was bought new Dec. 2015. I like it, hardly any kick. As fast as I can pull the trigger I can put them all into a paper plate. And, I am no sharp-shooter; this was my 1st semi-auto that I owned, and first time I’ve shot any hand gun in 18 years. I also have a .38 & .22 Smith & Wesson, like I said, it’s been 18 years. I’m no pro! The G42 fits me well.

    I love my glock 42 and have no issues using ball ammo. However the other day I bought Hydra-shok rounds and had a handful of hang-ups while chambering the rounds. I dont have this issue with rounded-Fmj style bullets but can someone recommend a JHP for the glock 42 that they havent had any feed issues with? I would like to carry this during the summer months rather than my .40 but i dont want my second round in the gun to hang up god forbid i have to use it
