Tactile lock plate components and methods

An identifying system for a firearm magazine, the firearm magazine having a floor plate having a distal side, a proximal side, and a passage extending through the floor plate from the distal side through the proximal side, the system comprising:

• a first lock mechanism for the firearm magazine, the first lock mechanism comprising:
• a lock plate, the lock plate having a base plate and a disengagement mechanism affixed to a proximal side of the base plate,
• the disengagement mechanism having a protrusion configured to extend into the passage of the floor plate when the floor plate and the lock plate abut one another, and wherein
• the protrusion has a first portion a second portion,
• the first portion configured to extend into the passage of the floor plate,
• the second portion configured to extend through the passage of the floor plate and protrude from the proximal side of the floor plate;
• and
• a second lock mechanism for the firearm magazine, the second lock mechanism comprising:
• a lock plate, the lock plate having a base plate and a disengagement mechanism affixed to a proximal side of the base plate,
• the disengagement mechanism having a protrusion configured to extend into the passage of the floor plate when the floor plate and the lock plate abut one another, and wherein
• the protrusion has a first portion, a second portion, and a third portion,
• the first portion configured to extend into the passage of the floor plate,
• each of the second portion and the third portion configured to extend through the passage of the floor plate and protrude from the proximal side of the floor plate.

A method, comprising:

• providing an identifying system for a firearm magazine, the firearm magazine having a floor plate having a distal side, a proximal side, and a passage extending through the floor plate from the distal side through the proximal side, the system comprising:
• (a) a first lock mechanism for the firearm magazine, the first lock mechanism comprising a lock plate, the lock plate having a base plate and a disengagement mechanism affixed to a proximal side of the base plate, the disengagement mechanism having a protrusion configured to extend into the passage of the floor plate when the floor plate and the lock plate abut one another, and wherein the protrusion has a first portion a second portion, the first portion configured to extend into the passage of the floor plate, the second portion configured to extend through the passage of the floor plate and protrude from the proximal side of the floor plate;
• and (b) a second lock mechanism for the firearm magazine, the second lock mechanism comprising a lock plate, the lock plate having a base plate and a disengagement mechanism affixed to a proximal side of the base plate, the disengagement mechanism having a protrusion configured to extend into the passage of the floor plate when the floor plate and the lock plate abut one another, and wherein the protrusion has a first portion, a second portion, and a third portion, the first portion configured to extend into the passage of the floor plate, each of the second portion and the third portion configured to extend through the passage of the floor plate and protrude from the proximal side of the floor plate;
• positioning the first lock mechanism in the firearm magazine to identify a first cartridge type;
• and at least one of
• replacing the first lock mechanism with the second lock mechanism to identify a second cartridge type, or
• positioning the second lock mechanism in a second firearm magazine to identify a second cartridge type.

An identifying system for a firearm magazine, comprising:

• a first lock plate and a second lock plate, each of the first and second lock plates having a base plate and a disengagement mechanism;
• wherein
• each disengagement mechanism has a protrusion;
• each protrusion has a first portion and a second portion, the first portion configured to extend a first distance from the base plate, and the second portion configured to extend a second distance from the base plate, the second distance greater than the first distance;
• and
• the protrusion of one of the first or second lock plates has a third portion, the third portion configured to extend a third distance from the base plate, the third distance greater than the first distance.
