The Dllama Firearms Manufacturing Model 151 is a fully or semi-automatic machine pistol chambered in the powerful .45 ACP. It features a foldable wire stock, suppressor, new hammer, new trigger, and larger 24 round magazine. The main differences between the DFM-150 and DFM-151 is that the 151 is chambered in .45 ACP (because .50 AE is to powerful) and the new wire stock. The new machine pistol also has beter internals to withstand the heat and kick from firing on fully automatic. Like all high-quality DFM firearms, this firearm is equipped with a polynal rifled stainless barrel. Price: 1300 USD. Military Price: 300 USD. Thanks and enjoy!
