Baldpriest Posted April 23, 2017 Share Posted April 23, 2017 Hi all! I recently got a brand new DVC Limited 40. I have around 700 rounds through it and found that my front sight moves freely 1/8" during the last stage of a Steel match Saturday. I have heard opinions of "loctite, due to not being able to drift it all the way off the slide by hand" and "replace with an oversize sight" I haven't drifted it off yet, but do have the brass punches to do so... I thought I'd throw a line out for opinions from the guys that have walked this path before me. Any help would be much appreciated!

davsco Posted April 23, 2017 Share Posted April 23, 2017 call or email STI Monday morning. that def shouldn't be loose. i assume you're talking the metal sight body and not the fiber optic insert. Link to comment Share on other sites More sharing options...

Correct, the metal body sliding in the dovetail. Link to comment Share on other sites More sharing options...
Woodsk Posted April 23, 2017 Share Posted April 23, 2017 My Son's DVC Limited .40 front sight fell off during a sectional. Less than a thousand rounds through the gun at the time. Link to comment Share on other sites More sharing options...

Woodsk Posted April 23, 2017 Share Posted April 23, 2017 (edited) At the time STI quoted six weeks to fit a new front sight. so we bought a manny dot from Brazos and fit it ourselves. that was just the beginning of the problems we had with the gun. Eventually we sent it to Atlas Gunworks to get it right. Edited April 23, 2017 by Woodsk Link to comment Share on other sites More sharing options...

If they are backlogged, I'll be doing the same... Link to comment Share on other sites More sharing options...
Mountbkr Posted April 23, 2017 Share Posted April 23, 2017 You can peen the dovetail, that should tighten it up enoughSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Trent1k1 Posted April 23, 2017 Share Posted April 23, 2017 Peen the edge of the dovetail on the sight. Link to comment Share on other sites More sharing options...

Sandbagger123 Posted April 24, 2017 Share Posted April 24, 2017 drizzle some wicking loctite into the slot and let it harden. or you can do like brazo and drill a hole for a 1/16 roll pin. or call STI and ask them to send you a new sight and fit it yourself.

I emailed STI late last night. Hoping for a response today. I've fit front sights on other pistols, so that option sounds good to me! Thanks!

davsco Posted April 24, 2017 Share Posted April 24, 2017 well the problem is whether the dovetail was cut too large, or the sights are too small or were filed too much. hopefully the latter. Link to comment Share on other sites More sharing options...

Agreed... Hoping it's just a small sight... I got an email back from STI, and they requested I send my slide in... I have DoubleTap Championship coming up, as well as some local matches soon, so I asked if they'd send a sight and allow me to fit it. Hoping they go for that...

incorrigible Posted April 27, 2017 Share Posted April 27, 2017 Same thing happened on mine. I removed the sight, staked the dovetail base with a center punch, cleaned off all the oil and debris, and put red loctite on it. After a couple matches, it is again just a touch loose. >_< So many issues with this gun that I'm swearing off stock STI's. Custom for any future purchases.

jimbullet Posted April 27, 2017 Share Posted April 27, 2017 this appears to be a fairly common thing with the DVC. Mine did the same with less than 100 rounds through it. I had the same issue and just got new front sights, peened the dovetail and then installed it. Very tough putting it in but I dont think it will ever come off now. The other thing I noticed was the screw under the rear sight is walking out. You might want to check this as I needed to put a bit of loctite.

For the forseeable future, I don't think custom guns are in the realm of possibility for me... So the DVC is my go-to gun, and maybe an Edge for a backup in the future...

If I don't hear back from STI, I'll need to purchase a front sight from Dawson and just get to work on fitting... when you peen the dovetail, you're talking about peening the sight itself or the slide? I'll check on the rear sight screw as well. Thanks for the "heads up"! Link to comment Share on other sites More sharing options...
Sandbagger123 Posted April 27, 2017 Share Posted April 27, 2017 if you want a almost guarentee no move sight just do like brazo and drill a 1/16" hole in the sight through the slide and put a 1/16" pin in it. if you ever want to replace the front the hole will be covered anyways with the new sight.

I just called STI and they agreed to send a new sight out. I'll fit it myself, and will seriously consider pinning if this one moves... It will be interesting to inspect the dovetail in the slide once the old sight is out... I'm curious to find the root-cause here... Thanks!

motosapiens Posted April 27, 2017 Share Posted April 27, 2017 i expect the root cause was the dovetail was cut too big, or the sight was filed a smidgen too much and then it got banged on a port or something. it is not unheard of. my solution to these problems is to remove the sight, pen the bottom of the sight in a few places with a punch and reinstall it. most times that will work and you won't have to beat on the gun itself.

Ah! Good info! I was hoping it was the sight itself and not the slide that folks peened... I talked with Ryan at STI and he is sending a new front sight out. I'll fit the new sight asap and post results. Thanks all! Link to comment Share on other sites More sharing options...

This was also my first impression (dovetail cut to wide)/ I took a caliper out though and they appear to be within spec (at least with my other STI 2011. So I think they filed the sight itself too small somehow and they keep on repeating this from what I can see as there are lots of us with the same issue.
