The G43X is part of Glock’s Slimline series, delivering a 10+1 capacity in a frame that remains easy to conceal. At just 3.41 inches, the match-grade barrel keeps overall length down while maintaining standard Glock accuracy and reliability.
The slide has front and rear cocking serrations for confident manipulation and has been precision-milled to accept a micro red-dot sight. This is a non-MOS model, so the milling gives you optic capability without adding bulk.
A set of Trijicon tritium night sights replaces the stock polymer blades. The green-lamp front dot and twin rear lamps offer excellent visibility in low light, a decisive upgrade for defensive carry.
Glock’s Safe Action triple-safety system and a 5.5-lb striker-fired trigger maintain familiar, consistent performance. The pre-rail frame preserves the slim profile, eliminating snag points while still providing Glock’s proven polymer durability.
Made in Austria, this G43X carries Glock’s matte black nDLC slide finish for enhanced corrosion resistance, and it ships with two factory magazines and all original accessories.
