A highly detailed 3D model of a futuristic, sci-fi-inspired handgun designed with sleek, imaginative aesthetics. The gun is primarily a vibrant or metallic blue with accents in silver, black, or glowing cyan to highlight key features. It has a compact, ergonomic shape suitable for handheld use, with a modern grip, digital indicators, and advanced design elements like energy cells, vents, and holographic sights. The surface should feature realistic materials with subtle reflections, textures, and wear to give it a slightly used, battle-ready appearance. The design combines elements of real-world handguns and fictional tech, making it ideal for use in a sci-fi or cyberpunk game environment.
