G-Magnum 1250 Whisper IGT Mach1 – an air rifle for enthusiasts of precision and power

Imagine: you are looking for a powerful air rifle that will not let you down at long range. The Gamo G-Magnum 1250 Whisper IGT Mach1 is exactly what you need. This break barrel air rifle combines innovative gas technology with impressive performance of 45 Joules. It is designed for experienced shooters who are serious about precision shooting at distances of up to 80 metres.

Our experience with this air rifle

What immediately stood out to us when testing the G-Magnum 1250 is the combination of power and control. The IGT system (Inert Gas Technology) makes cocking surprisingly smooth for an air rifle of this power. The polymer stock with metal reinforcements feels solid without being excessively heavy. At 3 kilograms, this air rifle sits stably in the hand, which is noticeable when aiming.

Technology and performance

The gas piston technology is the beating heart of this air rifle. Unlike traditional spring systems, the gas piston delivers consistent performance regardless of temperature or duration of use. With a muzzle velocity of 380 m/s and an energy of 45 Joules, this is one of the most powerful break barrel air rifles on the market. The Whisper moderator is integrated into the design, noticeably reducing the shooting noise without compromising performance.

Use and operation

Loading is done by breaking the barrel downwards – the typical break barrel principle. The single action trigger is adjustable, allowing you to set the firing moment exactly to your preference. The manual safety catch is logically positioned and easy to operate. For aiming, you have a choice: use the included 3-9x40 rifle scope mounted on the 11mm dovetail rail, or rely on the fibre optic front and rear iron sights for quick target acquisition.

Who is this air rifle intended for?

This is not an entry-level model. The G-Magnum 1250 Whisper IGT Mach1 is developed for advanced shooters seeking maximum precision and power. Due to its powerful performance and weight of 3 kilograms, this air rifle requires experience and a stable shooting stance. Perfect for those who want to push their limits in precision shooting.
