Gas Ram

The Gas-Ram (or gas piston, gas strut) is an internal propulsion mechanism that replaces the traditional metal spring in spring-piston airguns. It is placed inside the cylinder and consists of a sealed piston with compressed gas (usually nitrogen or inert gas). When you cock the pistol, the piston is compressed; when you fire, the gas expands and pushes the piston to propel the pellet.

Its advantages are:

• Longer lifespan compared to some conventional springs
• Lower noise and smoother operation
• Reduced recoil
• Immediately ready at low temperatures
• More linear behavior during cocking/firing, easier cocking in some guns.
• Less maintenance required compared to broken/damaged springs.

Single Function

It means that the trigger performs only one action: it releases the hammer to fall and fire. The trigger does not cock the hammer by itself.

- Trigger feel: Usually light and with a shorter travel compared to Double Action.

- Accuracy: The lighter and crisper character reduces loss of aim when pulling the trigger. For this reason, it is a common choice for competition/target pistols and for shooters who prefer fine control.

- Speed: Although the SA trigger is quick to pull, it requires time/movement to cock before each shot.

- Safety: The light trigger can be more sensitive to accidental discharge if not handled properly. It is often combined with other safety mechanisms.
