HJP Products Sight Pusher Universal Adjustment Tool

Great price and product. It does its job well, it takes a few minutes to adjust everything and familiarity, but overall great. Some reviewers mentioned the lack of spacers or having to impervise to raise and snug the object to the vise. It wasn't a problem for me to do that. You paid 40 bucks, don't complain about having to do alil extra labor or make impervised spacers. I cut out 2 little cardboard squares, taped them and that help me raise the object exactly the height I needed to. I didn't use a vice to hold the sight pusher in place, so don't be concerned about that, it would help but not needed. I used a 3/4 and 19 size too work the sight pusher. You can also install a red dot base plate with this, a EGW to be exact. Great tool, completed the job, take your time in the small project and save yourself the hassle of paying and taking it too someone else.

I bought this product because the rear sight in my concealed carry firearm was offset after taking a tumble at the range. Instead of paying for a gunsmith to fiddle around with it, I decided I'd try my hand at fixing the problem with this sight pusher and a laser boresight. It didn't come with any instructions on how to use it, which was somewhat disappointing, but it was easy to figure out the mechanics of it. Where I did struggle was lining up my slide and rear sight within the sight pusher tool. I had to find a sweet spot where the slide wasn't too high and wasn't too low. The problem is that the dots on my rear sight would get in the way of the pusher before the pointed part could reach the dovetail section of the sight. So I had to keep it low enough that it wouldn't get in the way, but high enough so that the sight could slide over the retaining block as I moved it. Once I figured all of that out, it worked like a charm and did exactly what I wanted it to. (The firearm I used was a Smith and Wesson M&P Shield)

I am very happy with this sight pusher. I'm not a gunsmith, but a hobbyist. I would normally use a brass drift to uninstall and install sights. In this case I had a fairly pricey set of night sights to put on a Glock 17 slide. All the info that I found said, "Do Not drift them in". Apparently tritium is enclosed in glass and can break if the sight is drifted into place. Front is no problem, a screw and some blue loc-tite. The existing rear was held by 2 set screws. It was off in a few seconds. The new rear sight started into the dovetail fine. I pushed it in flush with a small C clamp. The side of the sight was tapered so I used the tapered side of the pusher block to go the last 3/16" to center the sight. (The opposite side of the block is flat so they have it covered either way). I believe it took longer to write this review than it did to do the install. If you are apprehensive about doing this type of work, there are several online videos using this exact tool and will help you more than written instructions. (Which are not included). You could certainly spend more for a sight pusher, but I see no reason to.

The good: It works!The bad: Only once ...maybe twice if you're careful with it.I basically destroyed mine trying to crack the Loctite holding the sights in place. It's still cheaper than a gunsmith and it didn't mar either the gun or the sights.

Works as described. A paper is included inside the package with a link to a pdf. with instructions for use. Those online instructions also include a link to a YouTube video which was extremely helpful. I can say this definitely works as-is for an original series S&W M&P or M&Pc on both front and rear sights (you remove the bottom block from the tool for use on the front sight. It certainly works for use with standard-height sights, though I'm doubtful it would work as-is with "suppressor-height" sights. When used on standard-height sights, it required lots of precision adjustment before it would work--the vise blocks that clamp onto the gun slide are so high and close to the traveling sight pusher, that when pushing the old sight out of the rear dovetail, it wants to hit the vice blocks instead of slide out above them. When you push the slide up higher in the vice so the sight will clear the vice blocks, it makes the traveling sight pusher finger contact the sight so low that it digs into the thin side edge of the dovetail. It actually marred my new sights, crushing this thin edge. However, with the proper adjustment, it does the job. Maybe with experience now, I might could do it again without damaging the new sight at all.The YouTube video shows use with a 1911, and I can imagine a lot of other flat-sided slide handguns that it would work on. For use with angled or stepped-sided slide guns, the company suggests they make optional shaped-sided vice blocks.

Calling this a tool is a very large exaggeration. My initial opinion of the product was poor quality and lack of detailed instructions. Even going to the website for the instructions provided little information. The tool does not work for glocks, or at least I could not figure out how to use. Calling their tech support was useless. The operator could not be heard and kept needing to "make adjustments" so I could hear her. At one point the "adjustments caused me to hear all my side of the conversation delayed. This never got worked out during 2 calls. The operator also was difficult to understand even at normal volume do to a language/accent issue. Once I was able to explain my needs she said she was not able to help but would email an "expert" and they would get back to me at some undetermined time. I should have known better and just gotten one of the quality pushers instead of getting a cheap POS.
