Glock 17 rear sight adjustment

[Mike_mds]

My gen5 Glock 17 is shooting a bit to the left. Approximately 3 inches at 15 yards and proportionally worse at 25+. (Confirmed by someone who shoots better in their sleep than I do awake)

I bought a sight adjustment tool and was wondering if anyone had an idea of how much of a correction I should start with…are we talking moving it a millimeter to start? Any tips on this procedure to share?

Quick scribbles... that's 3" off at 540 inches out... which is .0055555555 off at 1 inch.... or .0372" off at 6.69" inches out(g17 sight radius)... orrrrrrrr about .95mm. So try 1mm right and see where you hit.

Yes about 1 mm to right should do it

I disagree. More like a smidge.

That graphic is enough to drive a dyslexic into a stupor.

LOL…thanks! Just seeing the math gave me a headache.

By my calculations, bump it over a cvnt hair.

What sight tool you go with ?

****Sometimes people just bang the sight up against the corner of a curb!

(Admittedly a sight tool is a more elegant option!)

Red, brown, or blonde?
There is a difference you know.

So I ended up buying the ATG Heavy Duty Universal Pistol Dovetailed Rear Sight Pusher Tool off of Amazon. I’m liking it a lot…was stupid simple to use and well built. A little painters tape and a ruler and I adjusted the sight 1 mm to the right. Lucked out that my guy who tested it originally was at a local range on Saturday and ran the gun over to him for testing. Ended up moving it a thin red one back to the left and he was killing a one inch box at 15-25 yards. Outrider’s math skills were right on the money…it was probably right at the .95 mm shift he suggested.

I typically just lock the slide in a vice and then use a hand-clamp with a pusher-dowel to squeeze sights on or off. Works like a charm and you can make pretty small adjustments this way. Plus if you do any woodworking, you should already have plenty of clamps clamped around.

My 8th grade shop teach voted me Most Likely to be Killed in a Home Improvement Accident so I opted for the sight pusher tool.

Lol! I voted my best friend, who is in the same construction business I'm, most likely to take a limb off. Well, I'm happy to report, he is retiring this year along with me with all limbs firmly intact.

Nope, two pinches.

Just do a skosh at a time. Could only need a skosh and a half.

This makes much more sense to me than the silly metric sytem
