Lyman Accusight Pistol Sight Installation Tool

After researching sight pushers for quite some time, I finally decided to try the Lyman AccuSight pusher. I needed a strong but gentle dovetail sight pusher to remove the front Trijicon Tritium night sight that I had sent to Novak's to get the front dovetail cut milled for the new dovetail front sight for my Colt Government Model Delta Elite 10mm - Novak's also installed the new dovetail front sight while they had the slide and sight in hand. The slide already had a GI dovetail slot from Colt. I looked far and wide and weighed the pros and cons of MANY sight pushers before determining the Lyman tool looked to be designed well and had enough reviews with good results and recommendations to get me to try it. Then the search was on for where to buy and and I found it with the best price at Midwest Gun Works and ordered it. I had earlier (2-3 years prior to the Lyman tool) bought another brand sight pusher that worked "OK" for removing the original Colt installed black non-tritium rear sight and installing a MeproLight tritium rear night sight, mostly due to this sight having sides perpendicular to the pusher. However, the Trijicon front sight, with its angled base leading to the front sight blade, presented a challenge the other tool could not overcome without damaging the Trijicon sight and/or the milled dovetail slot, so I stopped before that happened. After receiving the Lyman tool, I first stopped to check it out physically, and once it passed this test, I read (and re-read) the well written use and care instructions that came with the tool. So, with a little trepidation I first applied protective tape to the round pads attached to the horizontal screw-in slide position locks as well as the top-side angular pad to hold the slide down vertically. I then carefully positioned the slide to the most perpendicular position to the tool base and then carefully adjusted the height for the bottom of the flat sided pusher block to just clear the top of the slide, so it would push as close to the location where the base of the sight blade and the top of the angled base are joined as possible, thereby minimizing risk to the tritium vile in the sight blade. So, having adjusted the tool, I proceeded to turn the handle to advance the pusher block to the left, to remove the Trijicon front sight, keeping a close eye on the pusher block when it got close to the sight blade base as well as how close it would come to the top of the slide. Satisfied, I continued to slowly turn the pusher screw handle, also paying attention to any increase in effort required to turn the screw. A couple of times I felt a slight increase and minutely backed off the pusher then moved it back to the sight base and continued with turned the screw and watching the pushed block as it slowly began visibly moving the sight to the left (my left as facing the muzzle). As I continued, the effort started to gradually become less and less and the sight itself seemed to be moving out of the slot a little faster until I finally felt almost no resistance when turning the pusher block screw. At this point I used my finger to see if it was loose at all and was pleased to find it was loose. I then backed the pusher block away and used my fingers to fully remove the front sight. YAY! This was a complete success. To confirm it was a success, I grabbed the sight and took it into a completely dark closet to see if it still had the same level of tritium "glow" and was gratified to see there was no loss in it's light producing ability. II then setup the tool to remove the MeproLight rear sight and was able to remove it even easier than the front sight. checked the front sight in the closet a few days later with the same results - no loss in light emitting ability. I now have great confidence in its ability to reinstall both sights after I've completed my overall goal of spraying KG Gun Kote K-Phos and two colors of their flat black and flat silver/gray on all parts of this pistol, to protect it from rust and corrosion. Getting all the parts ready for the KG Gun Kote application is the reason I needed to remove both tritium sights, as they are not designed to handle the 325-F temp required for an hour to fully cure this product. Once the KG products are cured, I get to reassemble the pistol and reinstall the sights, which will be a quite an accomplishment as far as I'm concerned. So, with the experience I've now had with the Lyman AccuSight tool, I feel I can highly recommend it to others with 1911 pistols who need a good sight pusher for whatever reason they have for needing one.

Great tool!

The tool works perfectly. No more hammer and brass rod!
