Galco KingTuk

The largest IWB holster we’ve got for you today, the Galco KingTuk cleverly arranges its belt clips to allow you to tuck your shirt in over the holster shell. That dramatically expands your concealed-carry wardrobe and allows for solid retention and excellent concealment. Galco is famous for the quality of their leather and fittings, and the KingTuk is no exception. This big fella looks imposing, but once the panel is broken in it rides like a dream. The clips remain visible on the wearer’s belt, but they’re unobtrusive. We’re of the opinion that the added concealment from the tucked in shirt outweighs whatever you give up via the belt clips.

The panel is very effective at keeping the rig in place and the sweat guard does a great job of protecting your side from the pistol’s jabbing, not to mention keeping the pistol safe from sweat and wear. Bear in mind though that this is a large, solid device with a mandatory back-panel, so for smaller people and people wearing very light clothing, it’s probably not the perfect choice. The KingTuk comes in an “Air” model as well, with a perforated back panel designed to help the user’s skin breathe. That’s worth looking into for those of you constantly out in the heat; for most of us, the standard model is plenty wearable. If tucking in a shirt is required by your lifestyle or job, this is one of the best IWB holsters for 1911 pistols, Glock 19s, and practically every other common carry gun – it’s comfy and it gets the job done in style.

Overall we think the KingTuk is one of the great examples of Galco quality. Even with the Kydex shell, (the low-profile nature of this holster makes a leather shell impractical,) the Galco’s quality leather work makes it a pleasure to wear. The quality is backed by a lifetime guarantee. We recommend this holster system for regular-size to large men who spend a lot of time in business casual clothing, and think that on the balance, it earns 4 / 5 stars.

The BLACKHAWK! IWB breaks things down to basics: you need a shell to put the gun in and a clip to keep it on your person. That’s what you pay for here, and that’s what you get – this minimal holster does the job while clocking in at a fraction of the size and weight of its competitors. Sporting a single belt clip and a padded nylon laminate shell, the BLACKHAWK! IWB approaches comfort from the “less is more” perspective. This makes for a discrete and effective appendix IWB holster.

We’ve heard tell that some models of this holster tend to ride high, and that can make appendix carry unpleasant or make retention feel precarious. That issue doesn’t seem to affect the Glock 19 model, though, so if you’re carrying the classic compact 9, this holster offers an economical, easily-concealable alternative to larger models. The lack of a back panel can make for some uncomfortable moments, however – those of us who are larger gentlemen might find that this arrangement allows the butt or receiver-end of the gun to dig in to the wearer’s side. Life is about trade-offs, and this holster offers ease of mounting and simplicity in exchange for a little bit of comfort.

Overall, we think the BLACKHAWK! IWB is a strong contender for “best backup holster on the market.” Your daily driver might be more comfortable or customizable, but nothing beats this model when you want to get dressed in a hurry and get out the door. The clip is durable enough to keep the shell in place, and the nylon fabric interior makes for a smooth and predictable draw. We give it a 3.5 / 5. You can find it for sale here on as well as at many local outfitters.

Alien Gear ShapeShift 4.0

We’ve covered this two-in-one masterpiece before and it holds just as true when we’re discussing the best IWB holsters for Glock 19 pistols – the best IWB holster can be carried OWB as well! That versatility with Alien Gear’s quality reputation means that this holster is one of the best on the market for IWB carry. The key feature is adjustability – everything about this holster can be customized, from the angle to the carry position to the position of the shell. In fact, the Core Carry Pack is really two holsters in one, which helps to make up for the fairly high price.

Alien Gear’s choice of materials for this holster lives up to that of their previous offerings; the durable Kydex shell and flexible back panel will keep your pistol in place and protected from wear for many years to come. It’s all backed by their lifetime guarantee, so feel free to get as rough as you need to while sporting this setup. You’ll need a solid belt for the clips to mount to, but outside of that this holster can work with practically any outfit. It’s not the smallest out there even in its low-profile configuration, but it does a very strong job of concealing and protecting your firearm, which is ultimately what it’s there for.

We love Alien Gear’s products and the Shapeshift 4.0 represents the absolute top of the line. The company has been refining their brand for years, and this latest offering feels like the distilled essence of every successful feature they’ve previously deployed. This is not a budget holster, but it’s not meant to be. We rate the Shapeshift 4.0 at 4.5 / 5 stars due to its high-quality manufacturing and incredible versatility.  F

Overall, your Glock 19 can rest easy in any of these three pieces of kit; the one you pick may depend on your style and budget, but you can’t go wrong with any of them. We’d put the Alien Gear Shapeshift 4.0 in first place, followed by Galco’s KingTuk, with the BLACKHAWK! IWB coming in a very close third. Whether you’re off to the range or out and about, these holsters will serve their purpose and never let you down.
