Nighthawk Custom is now offering a double stack 1911 configuration as an upgrade option for all government and commander model 9mm guns we make except the Agent 2 and Thunder Ranch models. If you have always loved the slick lines of the 1911 platform but limited capacity held you back, here is your chance to get the best of both worlds. We are pleased to say that after over two years of development, we have created a double stack 1911 worthy of putting the Nighthawk Custom name on. Regardless of model, this upgrade will be priced at $650. *This upgrade is available only on new builds and is not available on pre-existing pistols.
