Concealed Carry Considerations

The Glock 43X, with its slimmer frame and lightweight design, offers an edge for concealed carry, particularly when wearers seek deep concealment. It measures just over an inch in width, which allows for a more discreet profile under clothing. On the other hand, the Glock 19 is a compact firearm but is bulkier due to its double-stack magazine, making it less ideal when minimal printing is a priority.

  • Glock 43X:
    • Width: 1.06 inches
    • Preferred for: Deep concealment
  • Glock 19:
    • Width: 1.26 inches
    • Preferred for: Balance between capacity and concealability

Holster Options

Holster choices are pivotal in enhancing the concealment and comfort of carrying a pistol. The Glock 43X, due to its single-stack design, can fit into various slim holsters that can be easily hidden. Common holster styles for the Glock 43X include IWB (Inside-the-Waistband) and ankle holsters, which benefit from the pistol's slender profile.

  • Glock 43X Holster Examples:
    • IWB Holsters for enhanced concealment
    • Ankle Holsters for alternative carry positions

Conversely, the Glock 19, although still a compact model, may require larger holsters to accommodate its wider frame. Despite the larger size, a vast market of holster options is designed for comfort, including OWB (Outside-the-Waistband) and paddle holsters for easier access.

  • Glock 19 Holster Examples:
    • OWB Holsters for comfort and quick draw
    • Paddle Holsters for convenient attachment and removal

Selecting the right holster is crucial for balancing concealment, accessibility, and comfort for the wearer.

Capacity and Firepower

Magazine Options

The Glock 43X utilizes a slimline single-stack magazine designed to maintain a slimmer profile for concealed carry. On the other hand, the Glock 19 is compatible with double-stack magazines, which offer increased capacity.

Shield Arms offers an aftermarket option for the Glock 43X, allowing users to upgrade the magazine capacity without significantly altering the firearm's size.

Round Capacity

Looking specifically at round capacity, there is a notable difference between the two models:

  • Glock 43X: Standard magazine holds 10 (+1) rounds of 9mm.
  • Glock 19: Standard magazine carries 15 (+1) rounds of 9mm.

These capacities can be extended with aftermarket magazines or extensions, but they are the manufacturer's standard capacities.

Optics and Modularity

Both models take a different approach to optics and modularity. For instance, the Glock 43X MOS (Modular Optic System) facilitates the mounting of various optics directly to the slide, a feature that increases its appeal for users seeking enhanced sighting capabilities. The Glock 19, by design, includes a universal Picatinny rail for attaching lights and lasers, and while it does not come standard with MOS, aftermarket slides or mounting plates can rectify this.
