The invention claimed is: 1. A sighting device for a firearm having a handgrip having a front strap, a back strap, and a free end, the sighting device comprising: a body including a sleeve defining a bore sized to closely encircle at least a portion of the handgrip; the sleeve having a front portion configured to wrap about at least a forward front strap portion of the handgrip; the sleeve having a rear portion configured to wrap about at least a rear back strap portion of the handgrip; a laser device connected to the body; and wherein the device is free of any fasteners engaging the firearm. 2. The sighting device of claim 1 wherein the laser device is rigidly connected to the sleeve. 3. The sighting device of claim 2 wherein the laser device is enclosed in a laser housing that is integral with the sleeve. 4. The sighting device of claim 1 wherein the front portion and the rear portion are integrally formed with each other. 5. The sighting device of claim 1 wherein the body is formed of a rigid thermoplastic. 6. The sighting device of claim 1 wherein the front portion of the sleeve includes an activation switch operably connected to the laser. 7. The sighting device of claim 6 wherein the firearm defines a medial plane and the activation switch is positioned on the medial plane. 8. The sighting device of claim 1 wherein the front portion of the sleeve is configured to be positioned immediately below a trigger guard of the firearm when installed on the firearm, such that a user's middle finger of the trigger hand naturally rests on the forward portion when gripping the firearm. 9. The sighting device of claim 1 wherein the front portion of the sleeve has a limited width extending along the length of the handgrip, and the limited width corresponds to the width of an adult finger, such that a third ring finger rests directly on a forward portion of the handgrip immediately below the forward portion of the sleeve. 10. The sighting device of claim 1 wherein the rear portion of the sleeve is positioned at a level below the front portion when installed on the firearm. 11. The sighting device of claim 1 wherein the rear portion of the sleeve has a limited width, substantially less than the length of the back strap, such that a majority of the back strap is exposed when the device is installed on the firearm. 12. The sighting device of claim 1 wherein the rear portion of the sleeve is configured to be positioned below a midpoint of the length of the back strap, such that an upper portion of the back strap is exposed when the device is installed on the firearm. 13. The sighting device of claim 1 wherein the firearm has a protrusion, and wherein the sighting device includes a lock element configured to the protrusion, such that the sleeve is retained against removal from the handgrip by the lock element engaging the protrusion. 14. The sighting device of claim 13 wherein the lock element is removably secured to the body. 15. The sighting device of claim 13 wherein the lock element defines a lock bore, and the body defines a body bore, and the bores are aligned and occupied by a pin to secure the lock element to the body. 16. The sighting device of claim 13 wherein the lock element has an upper portion located immediately above a portion of the protrusion when the lock element is installed, such that the upper portion engages the protrusion to prevent the sleeve from being removed from the grip. 17. The sighting device of claim 1 wherein the sleeve defines an interior surface that closely conforms to the surface of the grip. 18. The sighting device of claim 1 wherein the sleeve includes opposed side panels, the side panels being joined at front portions by a front span, at lower rear position by a lower rear span, and at upper rear portion by an upper rear span. 19. A sighting device for a firearm having a handgrip having a front strap, a back strap, and a free end, the sighting device comprising: a body having a front portion configured to wrap about at least a forward front strap portion of the firearm; the body having a rear first portion configured to wrap about at least a rear backstrap portion of the firearm; a laser device connected to the body; and wherein the device is free of any fasteners engaging the firearm. 20. The sighting device of claim 19 including a second rear portion spaced apart from the first rear portion and configured to wrap about a rear portion of the firearm. 21. A sighting device for a firearm having a handgrip having a front strap, a back strap, and a free end, the sighting device comprising: a body including a sleeve defining a bore sized to closely encircle at least a portion of the handgrip; the sleeve having a front portion configured to wrap about at least a forward front strap portion of the handgrip; the sleeve having a rear portion configured to wrap about at least a rear back strap portion of the handgrip; a laser device connected to the body; wherein the firearm has a protrusion, and wherein the sighting device includes a lock element configured to the protrusion, such that the sleeve is retained against removal from the handgrip by the lock element engaging the protrusion; and wherein the lock element has an upper portion located immediately above a portion of the protrusion when the lock element is installed, such that the upper portion engages the protrusion to prevent the sleeve from being removed from the grip.
