Works well. Seems to be made as well as any name brand I've seen. Possibly a Wheeler under another name since those are imported as well. Use some grease or oil on your threads, and don't get too crazy with pressure. It should move with moderate hand pressure. Great purchase, I wish I had this a long time ago.

Works great, easy to use, it comes with instructionsVery well made, good quality.

Really well constructed. Good material. Much cheaper than the name brand but worth the price. Fits many different guns, and the adjustments are very good. I would recommend putting painters tape on the slide to prevent marring of the finish.

First off, I am not a gunsmith or armorer, so I have limited experience. However, consensus on the inter-webs is that M&P sights are notoriously difficult to remove and replace. I wanted to put night sights on a couple M&P pistols (9L 2.0 and Shield Plus) and to be able to refine their alignment if needed.Bottom line: This tool worked, and did not damage either the new sights or the old ones, which were removed. Rear sight took an uncomfortable amount of force to turn wheel, and resulted in a slightly tender thumb. However, for the price, versatility, and result, I would not hesitate to buy again. Seems sturdy based on heft, but I have not, and will not, use this extensively.M&P 2.0 9LAt first, I borrowed a friend's tool (not this tool). It worked for the rear sight, but would not work on the front sight of my M&P 9L 2.0 (5" barrel) because of the geometry of the slide and lack of a notch below the pushing block. Next, I used a brass punch and hammer to get the front sight out and new sight roughly in place. However, as you might expect, smashing something with a hammer lacked finesse and I was having trouble fine tuning the alignment of the new sight at home figured I would not have much luck at the range if I needed to do further adjustment. That's when I decided to give this tool a shot. Because the W Wiregear has that notch/cut-out below the pusher block, it worked perfectly to hold the long slide and nudge the front sight into alignment.M&P Shield PlusNext, I moved onto the Shield Plus. The front sight was relatively easy to remove and replace using the 90 degree side of the block. To hold the slide, there are 4 individual contact points that you screw down. I like that the tool has a series of lines etched in the surface that holds the slide. These lines allow you to make sure the slide is properly aligned (i.e. perpendicular to the pushing block), so you're applying force straight through the dovetail and not at an angle. However, I may have preferred the two-clamping-bar-style (like vise jaws) of my friend's tool in that (1) it did not require fiddling to get the slide aligned, and (2) did not create a pressure point on the thin material at ejection port. With the Shield, one of the pads/feet screwed down onto that thin section of the ejection port, when pushing the rear sight. I made it finger tight and did not try to really torque it down to reduce risk of future issues. Everything seems fine so far, but time will tell whether that area has been damaged or fatigued, and others may not be so lucky (e.g., because they use their ape strength and apply more force than I did). I reversed the pusher block to use the 45-ish degree side for the rear sight. The rear sight on the shield was DIFFICULT. The pusher block has large pushing surfaces, so there was no damage to the sights despite applying a lot of force. I found myself wishing for (1) a good surface to hold the tool while I cranked the wheel (I'd probably try putting the tool in a vise if I were doing it again), and (2) a larger wheel (or a nut that I could throw a wrench on to get more mechanical advantage). It worked, but my thumb was sore afterward from pushing so hard on the wheel's spindle.

I have other site pushers that are brand-specific, like for Springfield Armory.When it came time to change out several sets of night sites on my Sig Sauer pistols I looked at what was available on the market and decided on this one as opposed to the Wheeler.I watched several of the videos regarding this unit and watched people using them to install, remove and adjust sights and felt comfortable buying this one and trying it out.I was indeed surprised; I changed three sets of aging night sights on a P226 and two P229s without major problems.A few notes in no particular order:1. As with any sight pusher of this type you should always lube the worm gear prior to each use, it will make it much easier to turn.2. As others have noted the adjustable block that holds the top of the slide down is very dense plastic and should not mar the slide. The pads that hold the slide on each side however are made of steel, so I just cut up an old plastic credit card and slid the pieces between the four pads and the sides of the slide and had no marks when I finished. Please note there are lines milled into the base of the tool so you can see if the slide is parallel to the sides of the tool.3. As with any dovetail sight swap it doesn’t hurt to put a few drops of penetrating oil on the (old) sights and dovetail and let it soak a bit before trying to push it out. Once the sight is out clean the sight dovetail and lightly lubricate it to help the new sight go in, along with lubing the bottom of the new sight.4. Before starting this job put your new sights in a Ziploc bag and throw them in the freezer for a few hours; this will shrink them ever so slightly and make them easier to install in a tight slide dovetail. Take the new sights and place them into the dovetail and tap them lightly with a plastic hammer to get them started straight; the sight pusher (when properly adjusted) will do the rest of the work.5. Be advised that on some slides sights are to be removed and installed in a particular direction; i.e. on Sig P-series pistols both the front and back sights are installed from left to right and removed from right to left as viewed from the rear of the slide. YMMV depending on your make/model of pistol.All in all, this tool is reasonably well-made and competitively priced. If you read the instructions, exercise care and pay attention to the details you shouldn’t have any problems. Besides being able to install and remove sights this tool can also be used for sight adjustments, but be advised in order to do this you must remove the slide from the pistol.
