Pistols have a body having a grip, the grip defining a magazine passage, the body having a trigger guard defining a trigger space, the body having an upper surface, the body having a first mounting facility, an upper frame assembly removably connected to the body in a connected position, the upper frame assembly including a trigger element extending into the trigger space when in the connected position, a protrusion extending upward from the upper surface of the body, the protrusion having a forward-facing first bearing surface, and the upper frame assembly having a rear-facing second bearing surface adapted to abut the first bearing surface when in the connected position to transmit recoil forces from the upper frame assembly to the body. The upper frame assembly may have a slide rail. The upper frame assembly may define a horizontal slide plane.

Pistol

Pistols have a body having a grip, the grip defining an elongated magazine passage adapted to receive a magazine and defining a magazine axis, the grip having opposed left and right side walls and a front portion and an opposed rear portion, the body having an upper portion having a first linear interface element aligned with an attachment axis offset from the magazine axis, and a removable backstrap element adapted to overlay the rear portion of the grip and having a second linear interface element adapted to removably connect to the first linear interface element. The pistol frame may include slide rails defining a slide plane, and the first linear interface element may be parallel to the slide plane. The first linear interface element and the second linear interface element may comprise a sliding interface. The sliding interface may be a dovetail feature.

Pistols have a body having a grip, the grip defining a magazine passage adapted to receive a magazine, the grip having opposed left and right side walls and a front portion and an opposed rear portion, the front portion of the grip including a first front strap attachment facility, a front strap element having a second front strap attachment facility adapted to removably connect to the first front strap attachment facility, and the front portion of the grip defining a front path and the front strap element being an elongated element movable along the front path, such that the front strap element is removable for replacement by an alternate front strap element. A funnel element may be adapted for connection to the frame at a lower rim of the grip at an installed position.

Pistols have a body having a grip, the body having a trigger guard, the body having an upper slide interface surface defining a slide interface plane, the body having a first mounting facility at a forward end below the slide interface plane and at a level above at least a portion of the trigger guard, a dust cover having a rear end having a second mounting facility adapted to removably dock with the first mounting facility in an attached position, the dust cover defining an upper surface in the slide interface plane when the dust cover is in the attached position, and the first mounting facility and second mounting facility comprising a sliding interface. The sliding interface may be a dovetail feature.

The present invention is a semi-automatic pistol receiver assembly comprising multiple removable parts rather than single piece construction normally used in semi-automatic pistols.
