German Sport Guns (GSG) produces .22 LR versions of iconic firearm designs, including the GSG-5 (based on the HK MP5) and the GSG 1911 (a .22 LR 1911-pattern pistol). These platforms are primarily used for training and rimfire competition, where the low cost of .22 LR ammunition allows high-volume practice.
Upgrades for GSG rimfire pistols
GSG rimfire pistols — among them the GSG 1911 — can be tailored across the main competition upgrade areas:
Sights and red dot mounts – an optic or upgraded sights give a single focal plane for faster, more precise target work on a rimfire trainer. The GSG 1911 is a common example.
Grips – a grip that suits your hand makes hold and trigger reach more consistent shot to shot.
Triggers – a refined trigger sharpens the break and reset for tighter, more deliberate shooting. The GSG 1911 is a common example.
Compatibility is specific to each GSG model and generation — confirm the fit on the individual product page before ordering.
