A slide assembly for a firearm comprising a slide and an extractor assembly is provided. The slide includes a mounting recess about a top side of the slide, and a housing recess about a proximal end of the slide. The extractor assembly is mounted within the housing recess and includes a distal end for engaging a cartridge and a proximal end opposite the distal end. The proximal end terminates at a position adjacent about a mid-portion of the mounting recess. One or more retaining holes are provided within a proximal region of the mounting recess spaced from the proximal end of the extractor assembly. Firearm sights are attachable to the mounting recess via fasteners engaging the retaining holes. The retaining holes are arranged such that they do not interfere with the extractor assembly or other components within the housing recess of the slide.

A device implementable on a firearm includes a one-piece sight functioning as a rear sight or a front sight when installed on the firearm. The one-piece sight includes a notch and a user-facing side configured with a first surface aligned with the notch and a second surface on two opposite sides of the first surface. The first and second surfaces are sloped at first and second angles, respectively, to reflect an ambient light at different angles.

This invention discloses embodiments which disclose a handgun frame conversion and adapter system which provides for the conversion of use of a handgun frame from use with a first slide to use with a second and dissimilar slide (such as allowing a Glock® Gen 1, Gen 2 or Gen 3 slide to be used on a Gen 4 or Gen 5 Glock® compatible frame). Aspects of this frame conversion system include a conversion adapter which is installable and removable from the frame portion of the handgun, thereby allowing any one of a number of handgun slides to be mounted or installed on one frame.

A barrel-mountable accessory to couple to a muzzle end of a firearm barrel, including: a first side having an opening arranged to fit around the muzzle end of the barrel; and a second different side having a taper pin opening; and a taper pin insertable into the taper pin opening of the barrel-mountable accessory, wherein the taper pin includes: a length including a first region arranged to mate with a taper interface provided on the muzzle end of the barrel; the length further including a second region to contact a sidewall that defines the taper pin opening of the second side; and means for driving the taper pin into the taper pin opening, wherein the driving means is located on an end of the taper pin.

A firearm or a firearm retrofit assembly to provide the firearm with gas compensation to reduce recoil, wherein a barrel of the firearm or firearm retrofit assembly includes a length having an egress for gas propelled from a chamber inside the barrel, the firearm or a firearm retrofit assembly includes a compensation device to mount in front or behind a front wall of a slide associated with the barrel, the compensation device including: a first side having an opening arranged to fit around a length of the barrel; and a second different side having an opening to expose the egress of the length of the bore.

An optic guard for a firearm may include: a frame; and a bracket having a first side to attach to a firearm assembly, the bracket integrally formed with the frame or fixably attached to the frame at a second side of the bracket. The frame may be arranged to protect a top and sides of the optic when the first side of the bracket is attached to the firearm assembly. In some embodiments, the second side of the bracket defines an optic attachment, wherein the frame protects the top and sides of the optic when the optic is coupled to the bracket using the optic attachment. In some embodiments, the first side of the bracket may define a protrusion or opening to mate with an opening or protrusion in front of an optic mounting platform.

A modular handgun system comprises an elongated universal trigger frame having a barrel locking block, a pair of slide rails, and an accessory rail. The trigger frame is adapted to have a trigger assembly mounted thereto. The system further comprises a grip frame having an elongated channel and a hand grip extending downwardly from the elongated channel. The trigger frame is removably mounted in the elongated channel of the grip frame. The accessory rail of the trigger frame is positioned forward of a forward end of the elongated channel of the grip frame so as to be exposed. The system further comprises a slide and barrel assembly slidably mounted on the slide rails of the trigger frame.
