I have the same problem. The screws that came with it doesn't tighten it down. I called taurus and they sent a new screw. It's a flat head screw with a thicker head. So, it screws all the way in the torx screw would leave a gap. Problem is the flat head screw head isn't as wide so, it falls thru the slide cut out. Anyone else have this problem?

 

There was a young man on YouTube that had that issue I believe.

Do you know if the gunsmith used the standard front sight screw or the OEM screw? Looking on amazon, says the oem is a shorter screw.

 

Is the stock G3 front sight screw a t8 torx or a hex head? Thanks

 

Torx t8 screw

 

Thanks

 

Here is my solution to this exasperating problem. After doing a web search, most people identify the screw as the culprit. From my work on this I found that the main issue is the height of the nut embedded under the front sight that slides into the top of the barrel to position it. This nut extends too far down into the hole in the slide and screws keep bottoming out! Not knowing this yet, I decided to tackle the issue identified on several forums of the threads not continuuing all the way to the screw cap causing the screw to bottom out too early. I did try the original screw, which did tighten closer than the new ones, but not enough. Next, I decided to remove the top area of one of the new screws supplied by Ameriglo so that the screw would fit tight against the sight. With a very thin file, I decreased the screw diameter about .5 mm to allow the screw head to lay flush to the bottom of the sight. There was ample amount of threads left on the screw to still hold it down(see image). After this I was excited to screw down my sight and finish the install. BUT, even with the screw head lying flush to the sight bottom, it still left a tiny bit of wiggle room, that was not acceptable for me. So, I reasoned that the nut itself protruded too far into the front of the slide it would not allow a screw to pull the sight tight. Once again I got my small file and reduced the height of the nut from about .25mm to 5.mm, give or take(see image). I left the .5mm hoping that would be enough, so that it would still drop into the slide centering hole. With this combination, Voila, the screw was able to tighten the sight. I disassembled and applied blue threadlocker to the inside of the front sight threads, the inside hole of the slide and the threads on the screw. I made sure not to torque the screw too much to break it off while finishing the install. Some leaked out from under the sight, which I thought would be fine, and wiped it off with a QuTip. Time will tell if the sight will stay tight over time. I was so disgusted that Taurus would sell a product like this on their website and that Ameriglo would release a sight that would not properly fit the G3. I hope Ameriglo will fix this by decreasing the height of the nut to .5mm and help others avoid this frustrating situation. I hope this help others.

 

Weird. I bought the same sight from Taurus and it tightened up snug. No play whatsoever. Shot it. Still tight.

Bad batch of screws from Ameriglo?

 

I personally had that issue with the original screw from factory and the one sent with my ameriglo sights. Ended up getting a screw from ace hardware that fit perfectly but it was a Philips head not a hex head. No issues since.

 

Had the same issue with my new front sight for my G3C. I filed the bottom of the sight down just a hair as it protruded through the slide. Made it fit flush, used the Glock hex screw and Loctite orange. Shot about 150 rounds with this and love it. Plus the sight FINALLY stays on. Like it so much gonna get one for my G2S as well

 

How long does Taurus take to ship these sights.

 

Welcome from northern Georgia! I bought one for my G3C and it came fast , maybe a week ? Call them or get online and see if they're in stock .

 

Just got mine. Fantastic! Installed quickly, and easy with original screws.
