Post subject:  Umarex Glock 17 Gen 4, Gun shoots low..anyone else?

My Glock shoots about 2" too low even at 15 feet
I've tried adjusting the hop up, but this did nothing...
I then removed the inner barrel from the barrel shroud and placed a few small pieces of black electric tape under the tip to help raise it up.
It made a little difference but not much,

Now my only option is to change the way I use the sights.
I know I could file down the front sights, but I'd rather avoid that

See below, I now have to aim as you see in diagram #2

I did not know that the Umarex Glock 17 Gen 4, .177 steel BB air pistol had "hop up". And did not think hop up had much effect on steel BB's. I thought it only worked on airsoft BB's.

Mine shot about 1.5" low at 24', when I first got it.

Now after using it about 10-15 times, it seems to be a bit more accurate. Doesn't shoot as low. Don't need to adjust the point of aim (POA) as much.

As I don't take my airguns apart to tinker with them as much as you do, I would recommend you try one of the following:

1) The simplest method would be to just adjust your POA. This is the method many shooters use on pistols with fixed sights.

2) Attach a red dot laser to the rail under the barrel & zero in the red dot. Although I have not tried it on this airgun, I have on others. All I can say is that the blowback may throw off the red dot, so a cheaper airsoft one may, or may not work. Might 1st want to try something like this:

Also, a more expensive one with red dot & flashlight is also an option.

But keep trying & experimenting.

Thanks BB1, I have a red Lazer, but Was hoping to just use the iron sights. I do adjust my POA , was just wondering is other had any new tricks.
Yes there is a small hop up screw and you can see down the barrel that the rubber lip is there, but I think you are right... they work better on light airsoft BB;s

It's a leftover from its airsoft origin.

Personally I would file the top of the front post slowly and check POI frequently until matches with POA. If the white dot on the post is recessed I would fill it with putty, sand smooth and paint the dot back on.

I was hoping to avoid that, but it's most likely what Ill do.

I think you will find that these types of replica air pistols, with fixed sights are not always that accurate. There are a number of reason why:
- They are mostly BB guns with short smooth bore barrels. Which by it's nature are prone to inaccurate shooting.
- People shoot at different ranges. Many of these are set up to shoot accurately at a certain distance, and therefore the elevation will be off a little.
- People have different shooting styles. Prior to Covid, I use to shoot a lot with friends, sharing the same airgun. We would sometimes get different results for the same gun.

I have a number of replica pistols with fixed sights. Some shoot dead on, right out of the box on my 24' basement range, some are way off. I'm not going to try to MacGyver each. I would rather just try to adjust the POA & install an under barrel laser. I try to make notes on the ones that are off & keep it with the gun. As I have too many to remember each & don't use some that often. Also, as I mentioned before, some of my pistols seem to shoot slightly different, once "broken in" or if you use different BB's. Read some of Tom Gaylord's gun reviews. He sometimes gets significantly different results using different BB's.

Would be interesting to know what people with real pistols do? As some don't have adjustable sights.

Factory fixed sights for PB pistols should be good for around 25 yards and need be you aim a bit higher for further distances. If not take it to a gunsmith for adjustment. If new take it back to the place of purchase for adjustment/replacement. Just make sure it's the sights and not you.

Tks for all the replies, for now I;ll just change my POA.

FYI, When started wondering if it was me shooting too low, I placed the gun in a vise and shot it on target indoors with no wind or movement, and yes the results were still that it shoots too low.

real guns iron sights are not much different from airguns iron sights, on some replicas they exactly the same. Real gun quality is better though, I never had to adjust sights so far. But if sight is adjustable you adjust it, if not - you replace sights, file them off a little, or just get used to change point of aim.

By the way there are a lot of different sights you can buy for Glock, so it might be possible to buy 3rd party Glock front sight and put it to Umarex G17.

There is even a way to adjust for windage on fixed sites:

99% of most powder burner pistols. The rear sights are in a dovetail milled into the slide. You push them left or right in the dovetail to adjust.

Airguns being that they're cast and to cut cost. Are normally just cast with them on the slide.

They are quite different. You adjust them by a sight pusher or a non marring punch. They're in a dovetail. Or installing taller or shorter front posts.

99% of PB pistols out in the market you can adjust the sights. Without filing. They cut cost with airguns.

Only time I seen 100% fixed sights, are older single action revolvers, or some carry pistols that have a groove.

As well, guns shoot differently for different people. It's the way they see the sights, hold the gun and squeeze the trigger.
As Leadslinger noted, air guns are made to cut costs. Adjustable sights, even those in dovetails requires "more" machine work, higher priced parts and thus much higher, overall prices than
what the mfg'r thinks the market will bear.
BB1 noted this: People have different shooting styles. Prior to Covid, I use to shoot a lot with friends, sharing the same airgun. We would sometimes get different results for the same gun.
Every one of my brother's rifles, iron sights or get this, scopes too, shoots 2" low for me at 50 yards with metallic sights, 100 meters with scopes - that's just the different way we see the
sights. On the other hand, my buddy Keith can sight in a rifle for me and I for him, irons or scoped. We shoot identically, yet we are not of the same "stature" at all.
