Not sure how to “sight in” my glock

I have a gen 5 Glock 45 that I put a zaffiri precision (spelling is probably wrong) slide and ported barrel on. I wanted to use irons so I put trijicon tough and bright sights on it and it shoots about 3 feet low at 25 yards. My shooting sucks so I had multiple other people who are decent to pretty good with a handgun shoot this thing and they all had the same results. What can I do to make the gun hit where I aim? Or do I just suck?

You just suck. Lose the fucking red dot and learn to be sufficient with your irons. When you hit absolutely EVERYTHING you put in them, THEN you can move forward. Stay in the back and learn to use your weapon system properly.

On a serious note… get a sandbag rest and shoot at 15 feet or so. Slow fire.

See where your poi is.

If it is still 3 feet low, your front sight is too tall!

Post some pix of your gun and sights. It will help.

Also you may get more useful answers in one of the technical threads. But, hey, we can try here!

Pix would help us!

First time at an indoor range with my G21 years ago. I wasn’t this bad but wasn’t great. No fundamentals. I asked a guy next to me if it might be “off”. He took it with ball ammo and grouped about 5” at 25 ft lol.

In the OP’s defense, tough and bright sites are not red dots. They are aftermarket blade front and channel rear.

Not a red dot!

Suspect that the front site he has fitted is too tall.

Cheers!
 
Use a ball-peen hammer and tap on the top of the front sight post. If it doesn’t get shorter then tap harder.
Test fire. Continue until it is sighted in.

Oh come on now… everyone knows that the “right” way to do this is with a Dremel!

I've always wondered if my foot is better medium-rare or well done. 😬

My bad boys!

OP,

The Front sight is the factor here. Always remember, Equal height(across the top), equal light(left and right). That's a good little training chant to recite before hand meets pistol too :) . Your dominant eye never leaves the front sight. Sandbag your pistol, sitting, from 10 yards for a baseline. Then go out to 25yds and see what happens. Also too, CENTER of your finger goes on the CENTER of the trigger and comes straight back. Not only in your sight picture, you'd be amazed at how your finger placement on the trigger can affect your shot placement down range.

Don’t preach at me for being a red dot bitch when I’m talking about wanting to keep my irons. That said I agree with everything you stated

I won't preach. But, I will most certainly bust your balls as brutally as I possibly can. Particularly if we were in a match squad together, and you couldn't hit shit with a red dot. 😁 If not in a problem solving workset, you would be COMPLETELY roasted at the range with a red dot mounted and no hits on target though, FYI.

Hope you get 'er fixed and back on target!

Try swapping one part at a time. Like old slide new barrel or new slide old barrel.
Only issue is the new barrel is ported for the aftermarket slide. I just wanted a ported barrel for fun otherwise I would’ve left the gun alone. Probably gonna try just the factory barrel in the aftermarket slide and see how it goes.

I’m wondering if there may be some major trigger jerking/flinching involved because the ports startle him

I have a 365 legion that I can shoot fine and a Springfield 1911a1 ported that I can also shoot just fine. I don’t feel any difference in blast to the face and other more experienced shooters get the same results with my Glock.

Have you shot it off a rest?
Yes but I have never shot paper with it. Usually find either steel or some trash, typically cigarette boxes (it’s what I find on the range usually) set them up at 20 yards and shoot them until they disappear or roll into the grass at 25 yards. Done this from various positions usually freehand. Sometimes resting on a bare bench or sandbag sometimes. I feel the poi is consistent.
 
Send it to me for research.🤣 seriously though, pistol sights have to be stupidly off to make a difference due to them being so close to each other. A 4” sight radius is very short and therefore requires major differences to make a difference. So as @Makinchips208 said it would be about 1/4” height difference. If anything from your pic it looks like the rear sight is taller than the front.
 
I guess what I’m looking for out of this is, has anyone else had iron sights on a custom Glock be off? How did you fix it? I don’t know of a place to get different height sights for glocks like 1911s and I really don’t want to use an adjustable sight or a red dot.
It doesn't appear to be a mis-match of sight height. Something with the barrel or slide being out of spec would be the logical suspect. As suggested above try swapping the parts around to see if it can be isolated given the factory parts shot well.

For what it’s worth, I sent a Glock 23 in for repair for a cracked slide. It cracked along the guide rail at the rear of the slide. Glock rebuilt the innards and built a brand new upper for it. So essentially brand new pistol for free. The cheap plastic Glock sights seemed funny. The front sight wasn’t level across the top and seemed too tall. Not a huge amount but my ocd couldn’t take it. A bastard file did the work for me and I filed it down flat so it was more aesthetic. Definitely improved my groups…

This is a fundamental problem. I’d look hard at your grip, glocks are very different than your other listed handguns. Also, you are probably breaking your wrist to hit that low but center, anticipating recoil. When you dry fire, is the gun dipping?

If you're filing your front sight down, there's only one real question worth asking, did you get that 8th of a second drop on good Sheriff Brady?

Never had Glock sights off from factory. But also never modified a Glock. I just take them out of the box and they are right on and go bang.

And yours look normal. At least no big anomalies!

Someone above asked about the barrel slide combo maybe being off… unlikely but possible.

Do a flinch check. Have a buddy hand you the pistol with a round randomly in the chamber or empty. If you re pressing the gun down hard in anticipation of recoil it will be very obvious. It is not uncommon for newer shooters to develop a flinch , especially with large ported guns.

Also get a big piece of paper or cardboard. Randomly shooting at trash on the ground is not going to give you the kind of site feedback that you need to diagnose the problem. Ideal would be a large piece of cardboard from an appliance box.

That or the broadside of a barn.

Cheers, Sirhr

Edit: PS Move way in from 25 yards. For diagnosing that big an anomaly, get into 5 yards. That way you can really figure out where things are going. At 15 feet, if the sights are messed up, it will still be hitting several inches low. Big cardboard (and masking tape to tape over holes) will be your friend! Cheers!
