From Walmart: HIVIZ FL2005R front shotgun sight $10 Folk Art Paint 2241 apple orchard $1.50 (in craft detpt. not toys) From Autozone: The Right Stuff Gasket Maker (Permatex) about $8 to $15 depending on tube or container size. The screw attachment tab needs to be removed from the HIVIZ sight (file.) Lightly sand the black paint from the bottom of the HIVIZ sight. Clean the attachment surfaces w/ isopropyl alcohol. Put a small gobbet of Right Stuff on the bottom of the sight then carefully place it behind the P-3AT sight. Don't worry about a small amount squeezing out from the join. Carefully position the sight. Let the adhesive cure for about an hour then carefully remove the excess Right stuff w/ a sharp fingernail. Let it cure for another 30 minutes then dress it up w/ a soft bristled toothbrush. If you goober it , just pry off the sight w/ a sharp piece of plastic, clean the adhesive off w/ mineral spirits or acetone and start over. The green paint should be obvious. The Right Stuff is heat resistant, oil resistant and flexible. The flexiblity compensates for differing coeficients of thermal expansion and resists shock both of which could break the bond. Some gun solvents may attack the hiviz plastic light bar and/or the adhesive. CLP doesn't seem to bother either. ANSWERS TO FREQUENTLY ASKED QUESTIONS: *No it doesn't snag in the pocket or holster. *The Armalaser is for darkness. The HIVIZ greatly speeds up front sight acquisition in all other lighting situations. *Technically the higher position of the HIVIZ would tend to make the point of impact lower. Shooting at silhouettes at fifty feet and under makes it a non-issue. *The adhesive is intended to be used as a gasket material for oil pans and valve covers and rated at a temperature of 450°F. I installed this front sight in September of 2006. I have since fired at least 250 rounds through the pistol. The gun has been exposed to a wide range of temperatures and is generally is carried a minimum of four hours per week.....there is no indication of the adhesive failing. *Yes I posted this several months ago...just before the server glitch....I think a lot of people missed it. *10/28/07 Yes I am modifying this post as follows because I have been catching some flak over the high cost of "the Right Stuff." The Right Stuff was selected over other very good adhesives for its adhesion , flexibility, resistance to lubricants and heat resistance (450°F.) ....The adhesive of choice needed to tolerate the mechanical shock in the application and the "squirm" of the differing coefficients of thermal expansion of the steel slide and the aluminum sight base. While the operation of the P3AT will not heat the slide to 450°F w/ normal usage the thermal cycling over time was of concern. The Right Stuff is designed to not fail due to thermal cycling. There are probably other adhesives that will work. I just wanted to make sure I wouldn't be fussing w/ this mod when I needed to be using it. Some people object to the cost of The Right Stuff. You will find other uses for The Right Stuff beyond just sealing and gluing. I have made wax carvings and models of parts from Sculpey (synthetic clay) to make impressions in open plaster molds for special grommets and bumpers. The Right stuff was just pressed into the mold and allowed to cure. *7/25/09-History update: This modification was completed 9/06. I carry the gun minimally 4 hours per week in my front right pocket, sport coat pocket or in a ballistic nylon brief. Conservatively 450 rounds have been cycled through the gun since the modification. Additionally the adhesive and sight have been routinely exposed to mineral spirits and Break-Free CLP with no ill affects.
