Firearms with an ambidextrous slide stop and/or relief

A handgun, comprising:

• a frame comprising an inner surface with at least one relief configured to capture debris away from moving parts;
• and
• an ambidextrous slide stop comprising:
• a first portion configured to be removably attached on a side of the frame of a handgun;
• a second portion on an opposite side of the frame of the handgun configured to be removably attached to the first portion of the handgun;
• the first portion comprising a first lever with a distal end and a proximal end, a shaft extending substantially perpendicularly from the distal end of the lever, and a stopper extending from the first lever, the stopper configured to mate with a stop notch on a handgun slide for locking and releasing the handgun slide;
• the second portion comprising a second lever;
• and
• a mating mechanism between the first portion and the second portion, wherein the mating mechanism comprises a male mating mechanism on the first portion extending from the shaft configured to removably mate with a female mating mechanism on the second portion;
• wherein the male mating mechanism is a post extending from the shaft and the shaft is integral to said first portion, and the female mating mechanism is a non-cylindrical protrusion with a recess into a surface of the second lever for receiving the post and extending perpendicularly from the second lever;
• and
• the first portion and the second portion, upon mating with each other via the mating mechanism, are configured to move operably with one another such that a user can engage the stopper on either side of the frame.

A firearm comprising:

• a frame, wherein the frame comprises an inner surface with at least one relief configured to capture debris away from moving parts;
• a slide slidably coupled to the frame;
• and
• a slide stop coupled to the frame;
• wherein the slide stop is configured to move in engagement with the slide to lock the slide and move out of engagement with the slide to release the slide, and
• the slide stop is an ambidextrous slide stop comprising a first portion associated with a first side of the frame and a second portion associated with an opposing side of the frame;
• wherein the first portion comprises a first portion lever arm and an integral shaft extending therefrom wherein the integral shaft is configured to extend into the frame and a first engagement feature extends from a distal end of the integral shaft and comprises a rectangular tab and wherein the first portion lever arm extends along an outer surface of the frame to facilitate operation of the slide stop from the first side of the frame;
• wherein the second portion comprises a second portion lever arm and a second engagement feature that is a protrusion, with an oblate spheroid shape having a centrally located recess and extending perpendicularly inward from the second portion, the centrally located recess being configured to receive the rectangular tab of the first engagement feature and wherein the second portion lever arm extends along an outer surface of the frame to facilitate operation of the slide stop from the opposing side of the frame;
• and
• wherein the first engagement feature is configured to engage with the second engagement feature such that when engaged, rotation of either the first portion or the second portion causes rotation both the first portion and the second portion.
