The M&A 9mm pistol is a semi-automatic handgun manufactured by M&A Guns Manufacturers. It is a recoil operated, locked breech pistol with a linkless barrel-to-slide locking system and an external hammer. It is a single action pistol, meaning the slide must be pulled manually to cock the weapon and make it ready to fire. The most common wasteland variant of the weapon has a dark grey finish and checkered wooden grip panels, with staggered magazines offering a tremendous 13 round capacity.
The M&A 9mm pistol is one of the most common guns to be found early on in the game, being very cheap to buy, utilizing very common ammunition, has no Gunsskill requirement and has a very low Strength requirement in order to handle it effectively. It has three-dot luminescent front and rear iron-sights for better low-light fighting, and a minor idle sway.

Dean's 9mm pistol, a unique non-playable 9mm pistol used by Dean Domino. There are two versions that are used: the first only differs from the standard pistol in its use of companion ammunition, while the second has increased level of damage (19 as opposed to 16).

In my opinion, the BHP is a timeless design and its form is quite distinctive when compared to Fallout's 10mm pistols. Also, since I knew we weren't going to implement an M1911-style .45, the BHP-based 9mm design gives an extremely similar aesthetic (so similar that a lot of people assume it IS an M1911) while fitting into the 9mm/10mm/12.7mm semi-auto handgun progression in F:NV.
