Glock G33 .357 SIG Subcompact, Gen4 Frame with Non‑Gen4 Slide/Barrel, FDE/Black, Upgraded Trigger, TG-H3 Night Sights, 3 Mags
This Glock G33 delivers the .357 SIG in a compact, carry-ready format with a tan/FDE polymer frame and black slide. It features a Gen4 subcompact frame paired with a non‑Gen4 G33 slide and barrel (mixed generation, non‑matching upper). The upper lacks the “Gen4” rollmark and the slide/barrel carry serial WUY283, while the frame is ZBN212. It is Austrian-made with a proof mark and AT marking on the barrel hood, and it comes thoughtfully outfitted with TG-H3 night sights, an upgraded trigger shoe, and an enlarged magazine catch. Three factory .357 SIG magazines and the original Glock case and manual are included, offering a complete package.

The G33 pairs a Gen4 subcompact frame with the stout .357 SIG cartridge, delivering a portable format with strong ballistic performance. This example features the FDE frame and black slide combination, plus the Gen4 enlarged magazine catch for easier reloads. Note: the slide and barrel are from a non‑Gen4 G33 and do not carry the Gen4 rollmark; the upper is non‑matching to the frame as detailed above. It retains the Glock Safe Action system.
The 3.43-inch steel barrel is nitrided and uses Glock’s polygonal rifling. The bore presents bright and clean. The barrel hood shows both a proof symbol and an "AT" marking, and the pistol is Austrian manufactured.
Upgrades include TG-H3 night sights for low-light aiming and an upgraded, two-tone trigger shoe for a refined interface. A rubberized slip-on grip sleeve adds traction without altering the frame, and a custom skull-motif rear slide cover plate provides a personalized touch.
Capacity is 9+1 with the included factory magazines. The magazines are correctly marked ".357" and "GLOCK AUSTRIA" with witness holes to 9. The subcompact frame has finger grooves and a smooth dust cover without an accessory rail, keeping the profile streamlined for carry.
