Custom Handguns
Build a Custom Glock 43X or Sig P365 Setup
If you are planning a custom handgun setup, Gas & Brass Armory also offers online builder pages for two of the most popular concealed carry platforms: the Glock 43X and the Sig P365. These builder tools make it easier to compare available parts, organize your selected upgrades, and build a setup that fits your needs before adding products to the cart.
The Glock 43X Builder is a convenient option for customers who want to customize a slimline Glock platform with available parts and accessories. You can review options for sights, barrels, slides, triggers, mag parts, mag releases, magwells, mounted lights, and other Glock 43X upgrades. This makes it easier to plan a carry-focused or range-ready setup while keeping your selected products organized.
The Sig P365 Builder helps customers explore available upgrade options for the Sig P365 platform. Depending on current inventory, you can compare parts such as grip modules, slides, barrels, comps, sights, triggers, mag upgrades, mounted lights, and related accessories. The builder is designed to help you organize your choices and create a custom Sig P365 setup that matches your preferences.
Both builder pages are designed to help customers shop more efficiently by showing available products in an organized format. Instead of searching through multiple product categories one at a time, you can use the builder pages to compare options by part type, review product details, and keep track of the items you want to purchase.

Whether you are upgrading a Glock 43X, building out a Sig P365, or planning a custom handgun setup, our team can help you review available parts, accessories, and product options.
