Concealed Carry

Review: Glock 48 9mm Pistol — The New Slimline

GLOCK 48 pistol two-tone with Gold Dot ammunition box

One of the great revolutions in handgun manufacture is the polymer frame, striker-fired revolution. Glock led the way and still dominates the market today. Arguably, Glock remains first with the most. I should note that I am not the greatest Glock fan, but I certainly am not a Glock basher.

The Glock is, in my opinion, the baseline gun for personal defense and a great choice for many shooters. The Glock is as reliable as a handgun may be, easy enough to use well, and chambers popular cartridges. If you spend less money than the Glock, then you should look hard at the pistol in question and determine what corners may have been cut. If you pay more than the affordable price of the Glock, you should be certain of the advantage.

The Glock 48 is a handsome handgun, light, and reliable.

If you choose a more expensive handgun with a different trigger action or manual safety, be certain you are willing to master the handgun. When you take a hard look at the alternatives, the Glock looks good.

One of the new introductions is the Glock 48 9mm. I do not form an opinion of any handgun until I have handled the piece and fired it for myself.

As an example, I was interested to see the introduction of the Glock 19X, which some felt was not a good idea. I liked the 19X, but I find the Glock 45 9mm a better fit for my preferences.

When you fire the piece and work it out on the range, the differences in handguns become more apparent. For some it may be the reliable and fast handling Glock 19, others may prefer the longer Glock 17.

All are good handguns. When testing the Glock 48, I expected certain things regarding reliability, trigger action and accuracy (as I would from any Glock), but other than that I kept an open mind.

Glock 48 Specs:

Length 7.3 Inches
Height 5.04 Inches
Width 1.1 Inches
Weight 19 Ounces
Magazine Capacity 10 Rounds
Caliber 9mm Luger

I do not have to be asked twice to go to the range. Some of you probably shoot better than I do, because you have a handgun that you stick to and have learned to shoot it to the best of your ability.

That is as it should be. At times, a particular handgun is worth moving up to, or in some ways moving down to if it is a compact version of a popular handgun.

The standard Glock sights allowed good speed and accuracy at close range.

The Glock 48 is perhaps two ounces lighter than the Glock 19 9mm and otherwise similar in dimension — save for the thinner grip frame and slide. The Glock 48 is thinner than the single-stack magazine Glock 19.

The pistol appears to have a stainless slide. The actual material is silver nPVD coating. The two-tone finish allows the Glock 48 to stand out in the showcase among the all-black guns.

The sights are the standard plastic Glock sight with a white outline. These sights work well for personal defense shooting at ranges of five to 15 yards and are useful for those that practice at longer ranges.

Glock 48 slide, top, Glock 19 slide, bottom
The Glock 48 slide is considerably thinner than the Glock 19.

The grip has an excellent feel to it. My hands are smaller than average, but I have never had a problem handling and controlling the Glock 17, 19, 22, 23 and similar frames (the Glock 21 is too much of a stretch). That said, I do feel more in control with the Glock 48.

The grip frame is nicely pebbled and offers both abrasion and adhesion when firing. These are not Generation-5 guns with ambidextrous controls and the other Generation-5 improvements, but rather they are straightforward modifications on the Generation-4 pistol.

The trigger action is the standard Glock Safe Action. My Glock 48 breaks at 5.7 pounds using a Lyman Digital Trigger Gauge.

This is the Glock 48 slim line magazine.

The Glock 48 balances well and offers a good hand fit. The pistol features forward cocking serrations. The slide features a lightening cut under the front of the slide.

The barrel features a nicely countersunk barrel crown. The interested shooter will find many good features on the Glock 48. The slimline grip holds a relatively thin 10-round magazine.

The question was, how does it handle in combat drills and when firing for accuracy. The pistol was lightly lubricated prior to firing and taken to the firing range with a likely assortment of 9mm Luger ammunition.

Testing the Glock 48

On hand, I had Federal American Eagle 124-grain FMJ and Federal 124-grain Syntech for the majority of firing.

Note countersunk barrel crown and open bottom of the muzzle.

I also had Federal 124-grain HST, Speer 115-grain Gold Dot, Speer 124-grain Gold Dot +P Short Barrel, Speer 147-grain Gold Dot, and Federal 135-grain Hydra-Shok.

This mix of ammunition included ball ammunition and both standard pressure and +P 9mm loads as well as a heavyweight bullet.

This should give an idea of how the piece handles all types of ammunition. The Glock 48 proved to be fast from the holster and fast to a first shot hit.

Glock 45 backstrap top, Glock 48 backstrap, bottom
The Glock 45, top, is a larger grip than the Glock 48, bottom, and both are nicely pebbled.

I burned up 100 rounds each of American Eagle and Syntech loads firing in realistic personal defense drills. The Glock is fast, very fast, and that means a lot in personal defense.

There were no failures to feed, chamber, fire, or eject. Control is little, if any different, from the Glock 19 9mm.

I would rate the pistol a bit easier to use well than the Glock 43X, since the heavier slide dampens recoil and the longer grip also helps spread recoil about the palm.

Note the grooved trigger face of the Glock 48.

Moving to personal defense loads, I found much of the same. Load selection is important.

While the 9mm offers good wound potential for the bore diameter, careful testing and research should be behind your choice. I prefer a loading with a good balance of expansion and penetration.

I fired at least a magazine of each JHP load — two magazines with some of the loads. The pistol is well regulated for the six o’clock hold and 124-grain loads.

The 147-grain load also strikes to the point of aim. Lighter loads may be used with the dead on the target hold.

The Glock 48 was tested with a wide range of loads.

At 10 and 15 yards, it wasn’t difficult to empty a magazine into the X-ring. Recoil is greater with 9mm personal defense loads, but the pistol remains controllable and overall pleasant to fire.

The Speer 124-grain Gold Dot +P is a short barrel load with a projectile designed to open at the lower velocities exhibited in short barrel personal defense handguns.

It has performed well as far as expansion goes and is a highly recommended personal defense combination.

I particularly like the 135-grain Hydra-Shok, but to each his own. The Glock 48 will exhibit the same velocity as the Glock 19, Glock 19X, and Glock 45, but it feels like a smaller handgun in the hand, is easier to conceal, and yet recoil is manageable.

Sight maintenance hole on the Glock 48 pistol
The hole in the bottom of the slide may have the effect of lightening it somewhat, but the true purpose is accessing the front sight for maintenance.

The pistol fired over 300 cartridges in the first range outing without complaint or sore wrists, spaced over a little more than 1.5 hours. Some may find the thinner grip makes for a heavier push in the palm than the Glock 19. In my opinion, the lighter Glock 43 9mm is a sweet-shooting handgun for its size, and the Glock 48 handles a bit easier. The longer grip frame allows a faster grip acquisition.

I also fired the piece from a standing, braced barricade for maximum accuracy at 15 yards. I fired the American Eagle 124-grain FMJ and Speer 147-grain Gold Dot in this drill. I fired several five-shot groups, firing quickly but regaining the sight picture after each shot. Firing a five-shot, three-inch group wasn’t difficult with some five-shot groups falling into two inches.

The pistol is as inherently accurate as any Glock 9mm pistol. Where does the Glock 48 stand in the scheme of things? The Glock 17 is a holster pistol that a few dedicated shooters wear concealed.

The Glock 19 is easier to conceal — and not a bad service and duty gun. The Glock 48 is a superior, concealed carry handgun. I think many shooters may find the Glock 19 a stretch for their hand size. I do not, but the Glock 48 may feel better for some shooters. Yet, you do not give up much in capacity as the pistol is a 10-shooter.

GLOCK 19 Handgun
Glocks are incredibly customizable handguns and are a great choice for your first handgun.

You do give up the ability to mount a light rail, so consider how important this is to you. You do not need grip inserts as the small grips fit most hands well.

The Glock 48 fills a similar niche to that once filled by the SIG P225. Although the SIG P228 holds more rounds, many shooters preferred the slimline P225 for hand fit and also felt that it was faster from concealed carry. The Glock 48 is fast, very fast, and offers a good chance at a rapid first shot hit. The extra two ounces of the GLOCK 19’s weight may make for better recoil control, but you cannot prove that easily.

I find the Glock 48 a very neat, attractive, and useful handgun. It may be the best Glock for concealed carry yet manufactured.

Who doesn’t love, or at least have a healthy respect for, Glocks? What’s your opinion of the Glock 48? Let us know in the comment section.

  1. Yes, I would buy a g48 if they made a long slide version, say 5.5″ and upgraded the specs to handle +p “all day long”. I’m getting tired of reading +p is allowed but “avoid a steady diet” or else (then ominous sounding music starts to play). For example, HK’s USP has metal plates embedded in the polymer frame to add strength. So go from a 38,500 PSI to 42K PSI. Is a 10 percent increase in PSI a mission impossible?

  2. I have a G48 and I love it. It is the best packing belt gun I use. I traded off a G19 because I liked the 48s thinner grip. If I were still working I would probably pack a G17 Gen5 for both uniform and off-duty. But being retired leaves me not needing the big gun. I also have a G43 for pocket carry. The 48 with 10 rounds is a good amount of ammo. Add one spare magazine and I am packing more ammo than I did working in the old days.

  3. Glock 48 is my concealed carry. I have a large hand and anything smaller than a G19 gets lost. The only complaint I had was the texture of the grip. As 90% of Americans have, I have a a little roll of Love over my belt in the carry area. This texture would bother me at the end of the day. So I smoothed off the sides and backstrap as well as some additional relief under the trigger guard to accommodate my large fingers. I do the trigger guard relief on all my Glocks. With the forestrap being the only textured part of the grip, that’s were my first point of contact on draw and I really don’t miss the nubs on the sides and backstrap. Someone with weaker hands, this might be an issue.

  4. There was no confusion on our part or need for comparison to other guns for clarification. You plain flat typed it WRONG. The glock 19 is a double stack, the 48 is a single stack. Simple. Most shooters on the planet know that. But for a newbie, there’s no way to derive that properly at all from what you typed though, commas or not. Its certain you know the difference in guns,
    but proofreading, like commas, matters too!
    PS- we only wanted to know how it’s different than our other glocks 🙂

  5. Wilburn, “The Glock 48 is thinner than the single stack Glock 19”. What? That isn’t correct. After that statement I couldn’t read anymore.

    1. Sir,

      Should have said, Thinner than a single stack Glock 19 9mm, the point being, the slide and frame of the G 48 are thinner than the Glock 19 it isn’t simply a slim line Glock 19. The SIG P225, as an example, is as thick as the high cap P 226 in the slide.
      Sorry for any confusion.

    2. I didn’t know Glock made a Single Stack 19. You probably meant thinner than a Double Stack Glock 19 Magazine. I didn’t even notice it though I should have.
