Model No. 4

The Model No. 4 was built with extreme accuracy and wringing the most possible out of the .50GI – a perfect pistol for hog hunting! The added 1” length not only helps with precision shooting, it also increases the velocity of standard 50 GI ammunition. Furthermore, the increased muzzle weight of the 6” slide and barrel allows more powerful 50 GI hand loads to be shot from the M4. Typically, velocity gains of 25% and muzzle energy gains of over 60% can be achieved, talk about reaching out and touching something – HARD! The Model No. 4 is a formidable handgun hunting pistol but also serves well as a back-up pistol in bear country or just for enjoying the sheer pleasure of launching .50 bullets with extreme accuracy – it’s a blast!

Even from afar the imposing six inch slide with that huge bore tells everyone you mean business. The M4 is a pride and joy around here and while held to the same standards as all Guncrafter Industries pistols, we know that an M4 customer will press the pistol to the limits and be happy to call in and let us know how we made the perfect pistol. Hunting, plinking, or chasing the smallest group the Model No. 4 will do its part.
*Note: The Pistols shown on the pages here may not represent a standard model and may have a number of options, please keep in mind that we custom build each pistol to order.
