SporGain Sight Pusher Tool for Square Slides, Heavy-Duty Aluminum Frame

Works great, not much to it I am glad I don'tnhave to chip away with a hammer to get the rear site out. Very sturdy

This was great for the price and I was able to replace the sights on several Glocks and a FN FNS-9. I don't regret buying it, but I probably screwed it up by pushing the sights the wrong way. I didn't try to find any directions and I don't remember if it came with any but I didn't read them if it did. So I'm here to tell you that if you buy this, only push the sights in the direction AWAY from the crank handle. Do not try and move the sights by pulling them towards the crank handle, it will work for a couple of times and then it will strip the bolt. Even then, it still works. You just can only push in one direction.

Works as expected. We were able to adjust the sights without much difficulty. The markings are not designed for micro adjustments, but with a delicate hand and some patience, we were able to zero in.

Product is terrible , didn’t fit my slide even with different adapter. I had to put in a vice , and still the tool moved and it was unstable. Would not recommend this product

Excellent quality. Easy to use.

Replaced the sites on two Glock pistols. Spent about 30 seconds figuring out how it works and how the slide needed to be positioned to work best. Took less than 30 seconds to remove the factory plastic site and another 30 to install the new site. Could not have been easier. Tool fits easily in my range bag so I can take with with me the next time I head to the range so I can make final adjustments on the site. Great price and sturdy too. Heavy enough that you have good control on the tool the whole time. Positive engagement of the site and it's easy to see when you have everything lined up properly.

Had to add a spring pin to the nylon nut as it had a tendency to untreated itself if to much pressure was applied. The base plate will let the gun slide shift even after having everything squared and tighten down. It did get the job done but I don't see it having longevity. Also the protection pads on all contact points are coming off as the glue is failing.

I bought this pusher to remove the stock Glock 19 sight and install a new AmeriGlo i-Dot sight. The good news is that this pusher was able to easily remove the stock sight and, with a bit more effort, able to install the very tight-fitting i-Dot. However, the tool is virtually useless at centering the sight. The markings at the top of the tool are way too far from the sight itself to be useful. Instead, I tried to use my high-quality digital calipers to measure from the frame of the tool to the sight. But then I realized that the fixed mounting surface on the right side of the tool (the left side has a moveable surface) doesn't center the slide at all. It pushes the slide off center to the left by a significant amount (about 10mm). So I had to center it by eye, then repeatedly remove the slide from the tool, measure with the calipers, put it back in the tool, push it right/left by smaller and smaller increments until it was centered. As far as I can tell, this tool is unable to center the slide or the sight by itself. Next time I'll take it to a gunsmith, who generally charges $35 -- the same price as this more-or-less useless tool -- or by a higher grade tool. One more small complaint: the bottom and left side holders have rubber pads. The top holder did not have a pad. As a result it left several very light lines on the top surface of the slide. It really should have a rubber pad as well.
