How secure are Glock factory rear sights?

[Biomortis]

I am wondering how secure the rear sights are on Glocks. I have an issue with the way the right armrest of my work chair catches the back end of my G27 slide every time I stand up. I've actually been thinking about manufacturing a kind of shield to attach to my chair to minimize this. Anyways, since the rear sights are just essentially wedged into the slot, has anyone here had an experience of having them knocked out of true by getting it snagged on something? They haven't moved yet but it only takes once to ruin my day. And for the record, I'd rather change my chair before I change my EDC, heh.

They are pretty secure, but anything is possible. I don't know the exact amount of pressure in lbs it takes to move, but with my sight press it takes enough to put a slight strain on my thumb to get it moving. If you have the original polymer sights I might be worried about damaging them but not necessarily moving them. If you have metal sights, I'd be more concerned about the chair.

Good luck!

I've never had a problem with factory sights. I have replaced them with Trig's, and have never had a problem with them either. Those suckers are TIGHT!

I too have never had a problem with the sites on my G27. But if it were a problem, I'd consider a change in carry position, or even a holster change.

If properly installed, it should take nothing less than a hammer and punch to remove a sight. Those are the tools I use to remove and install sights. I've worked on many guns and have yet to see a sight that was easy to remove.

Never had an issue myself, and owned/use glocks for both duty and self use.

The rear sights should be pretty secure although I do know of 2 guys at the Gun Club that issues with them. I do not recall what reasons they gave but they did come off. But being in Atlanta they just took them by Glock and they put new ones on (free).

I didn't think much of it until I gave it a once over last night and noticed that the right side of the sight was rounded over from the constant contact with getting hung under the armrest. I have since lowered the armrests. It isn't nearly as comfortable but now I don't have to worry about having misaligned sights. I'm overdue for some range time anyways. I'll get to check it this Sunday.

The Glock factory (plastic OEM) are very secure. They are not only wedged in to the slide groove, but there is a spring metal piece attached to the base of the site that exerts upward pressure as well.
IMO....change your position of carry, or get a different chair. If you need another Glock rear site (OEM plastic), just let me know.

Just take a black bic pen and melt a little plastic on there and you are good to go!

If you are anywhere near Smyrna, Ga. take it to Glock. All you need to do is show up there M-F during business hours. You'll usually be in and out in under 30 minutes. They'll not only fix your sights, they'll go over the entire pistol and replace any worn or upgraded parts. All for FREE! You can also get night sights installed, I think the Glock ones are $60 and the Trijicon are $75 (that's installed).

They slide out like butter. I wouldn't be too worried about your situation--I'd call it "highly unlikely" that the sights would move. It takes very specific pressure in a very specific direction--now, once you have that you can move them with your thumb--but without that, they're pretty stable.

I always--always--relace the sights with a set of Scott Warren's excellent offerings. The guy has developed a nice sight--rugged, lockable, with a wide rear notch and a narrow front sight post. And they're CHEAP!

Never had an issue with the rear sight on my Glock, but the front sight popped off.

I have never had a Glock rear sight move on me.They are very secure.
