Review: Wheeler Engineering Armorer’s Handgun Sight Tool

BLUF: It is good, but not great. It works, but it isn’t anything special. Other cheaper options will likely be easier and faster to use.


I found my self needing a sight adjustment tool and I was undecided which one to buy. This one ended up being my impulse purchase. I needed to install a front sight into a Sig P320 slide, and I read that using a punch and hammer is strongly recommended against.

Guys in the Army are breaking front sights trying to adjust them:

MSRP is about $150ish. I paid about $170 with taxes and shipping. You can likely find it cheaper elsewhere, but I wanted a sight pusher fast and I got this one the day after I ordered it.

It came well packaged in a branded box.

Once you take it out of the packaging, it is a pretty heft unit. Nicely built.

You have two large knurled nuts on the top that you unscrew to remove the top piece to put a pistol slide in the unit.

On the underside of the top piece, you have a height adjustable stop/guide that rests on the top of the pistol slide. It has a concave section for resting on top of 1911 slides, and you just turn it to rest the flats on top of any other type of slide. It can turn easily when there is no pressure on it.

The underside has four thumbscrews to press anodized aluminum clamps against the slide to hold it in place.

You put the slide in the lower, clamp it in place. Set the top of the adjustment tool back on the unit. Adjust the height with the height stopper mentioned previously. Reinstall the knurled nuts, then you can adjust the sight.


This is not hard, but it is not as fast or easy as other sight pushers out there.

I was at my local gun store today and noticed my dealer has one of these sitting on his tool cart. He was also installing some Glock slights today and he was using a different brand pusher instead of this one.

I don’t blame him.


The anodized aluminum pads on the base can scratch or mark up your slide. So you are suppose to tape up your slide first. I never had to do that with any other sight pusher. Not a bad idea though.

Now if you are paying attention, don’t worry. I took it back apart and assembled it correctly before I used it.

The sight pusher section, the black H shaped part, shown in the picture above, can be removed using an Allen wrench and flipped over. There is a part with straight ears for pushing most sights, and a part with slanted ears for pushing sights with angled sides, like you commonly find on a Glock.

Here is one of my minor complaints. You need to use a tool to adjust this tool for use. At $150, they could have drilled a hole one of the meaty metal parts, glued a little magnet at the bottom and set an $0.50 Allen wrench in it, so you would always have one with the tool. Better yet, they could have had a couple of steel indexing pins and a single thumbscrew hold it in place allowing for tool-less switching.

I found the markings for centering the front sight are a great idea, but they are faint on this pusher and I had a hard time seeing them while I used the sight pusher. They show up great in my photos, but at my desk, I struggle to see them.

I wish it had a larger handle. The manual tells you not to put any sort of cheater bar on it, I was tempted to do so. While this is a substantial size, it is still light enough that you need to secure it with one hand while you twist the adjustment spoked handle with the other. I found that kind of awkward. I’ll likely put it in a vise next time I use it.

I doubt this is something you would want to throw in your range bag to take with you in case you need to make field adjustments.

I’m not saying it is a bad product. It does what it is suppose to do. It hold a slide in place with five points of contact and applies pressure to move a sight. It works.

But it is expensive and it could be better and easier to use.

It got the job done.
