## Abstract

A firearm has a safety index that may be an elongate depression or an elongate convexity formed on a frame of the firearm adjacent a trigger of the firearm, and may further include a plurality of raised dots. The safety index is configured to allow a user of the firearm to move between the safety index and the trigger, as necessary, for instance, as the user goes between non-firing and firing conditions.

## Claims

### Claim 1

A method comprising:
providing a firearm wherein the firearm has a frame and a trigger extending from the frame;
providing a safety index having a plurality raised of circular dots extending in a straight line along a length of the safety index;
arranging the safety index on a lateral side of the frame of the firearm to allow a user of the fire arm to move the user's trigger finger between the safety index and the trigger without significant movement of the user's hand, and to allow the user of the firearm to sense the raised dots portion of the safety index with the user's trigger finger and to establish an off-trigger location for the user's trigger finger; and
directing a user of the firearm to move the user's trigger finger between the safety index and the trigger;
wherein the step arranging the safety index on a lateral side of the firearm includes adhering the safety index to the lateral side of the firearm.

### Claim 2 (depends on 1)

The method of claim 1, wherein the safety index comprises an elongate convexity.

### Claim 3 (depends on 2)

The method of claim 2, wherein the convexity comprises a kit associated with the firearm.

### Claim 4 (depends on 1)

The method of claim 1 wherein the step of directing the user includes providing instructions in the kit.

### Claim 5 (depends on 1)

The method of claim 1 wherein the step of directing the user includes instructing the user to place the user's trigger finger on the safety index to indicate a non-firing condition.

### Claim 6 (depends on 1)

The method of claim 1, wherein the step of arranging the safety index on a lateral side of the frame of the firearm includes arranging the safety index on a right lateral side of the firearm.

### Claim 7 (depends on 1)

The method of claim 1 wherein the step of directing the user includes instructing the user to place the user's trigger finger on the safety index to safely operate the firearm.
