awfaxis Posted June 11, 2015 Share Posted June 11, 2015 While developing loads, I noticed that all my expended brass coming from my new gun has this dent in the bottom. Doesn't match the ejector, so must be the slide stripping a new round into the chamber. No FTF problems, no bullet smiley's on the next unfired round. What's up with that? Getting this with 12 lb spring on 180 Xtremes pushing around 940fps, and on some low power 180's at <800 fps. Using a 10 lb spring on the sub-major loads.

jpl Posted June 11, 2015 Share Posted June 11, 2015 It is the breech face, on the ejector side, not flush with the rest of it. Fairly common, doesn't hurt anything and doesn't impact reliability or performance. You'd just think that they would check for this and address it before shipping. Check with STI and see if they'll fix it under warranty. Link to comment Share on other sites More sharing options...
awfaxis Posted June 11, 2015 Author Share Posted June 11, 2015 Yup, I see it now. Ugh. Thanks! Link to comment Share on other sites More sharing options...
awfaxis Posted June 11, 2015 Author Share Posted June 11, 2015 Curious if this will make my brass unusable? Link to comment Share on other sites More sharing options...
awfaxis Posted June 11, 2015 Author Share Posted June 11, 2015 Here's the little step on the breach face. Link to comment Share on other sites More sharing options...
Pat Miles Posted June 11, 2015 Share Posted June 11, 2015 The mark may make it a PIA to feed into the shell plate on your reloader. I have a friend who was having a similar problem with an STI. After much consternation I found that the breech face was not cut correctly and had a small area where it was not machined flat . Mark a round with a magic marker with the round showing the mark at the 12:00 o'clock position. Shoot the round and then look where the indent is being caused.

Pat Miles Posted June 11, 2015 Share Posted June 11, 2015 Is that a 9mm/38 super breach face? Link to comment Share on other sites More sharing options...
Ming the Merciless Posted June 11, 2015 Share Posted June 11, 2015 Is that a 9mm/38 super breach face? Neither I hope since the brass in the photos is .40 S&W. Link to comment Share on other sites More sharing options...

MrWallace Posted June 29, 2015 Share Posted June 29, 2015 Were you able to resolve this? My new CK slide is doing the same thing Link to comment Share on other sites More sharing options...
Agent #1911 Posted June 29, 2015 Share Posted June 29, 2015 (edited) Curious if this will make my brass unusable? it will probably wobble your brass in the loading press. have that fix coz im not picking up your brass!

ltdmstr Posted June 30, 2015 Share Posted June 30, 2015 I would definitely send it back. Kinda sucks they do crap work and then don't catch it with QA check. Link to comment Share on other sites More sharing options...
awfaxis Posted July 3, 2015 Author Share Posted July 3, 2015 I shot the Area 1 match this last weekend, and scored 2nd in C Ltd. It was overnighted to STI on Monday, and they said it would be turned around the same day and back in my hands by Friday (today). I have a match this weekend, and it was worth it to spend on the overnight out. Concerned though, as I haven't received any shipping notice for the return trip, and they closed for the holiday on Thursday. Link to comment Share on other sites More sharing options...
3djedi Posted July 3, 2015 Share Posted July 3, 2015 Sounds like no joy in getting it back today. Sent from my LG-D850 using Tapatalk Link to comment Share on other sites More sharing options...
MrWallace Posted July 3, 2015 Share Posted July 3, 2015 (edited) Ugh good luck! I filed mine flat. No issues with it stamping anymore. But then again, I'm also going to be getting mine coated soon since that hasn't been done yet and I'm sure you wouldn't want to have to do that.

awfaxis Posted July 4, 2015 Author Share Posted July 4, 2015 Got the slide back yesterday. They sent it Priority Mail (2 day). I spent $80 to overnight it, and it cost STI $8 w/ins to send it back. Oh well, its done, and they replaced the front sight for some reason. Now I have to go sight it in today. Link to comment Share on other sites More sharing options...
g.willikers Posted July 4, 2015 Share Posted July 4, 2015 (edited) Just looked at a bag of range brass from a recent practice session. Some of the cases had the mark, but not all - even from the same .45 gun and same batch of reloads. Hmm. Never a problem with anything from this gun, ever. Or the brass from it. Much ado about nothing, maybe? Edited July 4, 2015 by g.willikers Link to comment Share on other sites More sharing options...

awfaxis Posted July 6, 2015 Author Share Posted July 6, 2015 They provide a "ship to" normally for customers, but I wanted to make sure they got it in time for me to get it back for the match on the 5th. It all worked out, so I can't complain. Link to comment Share on other sites More sharing options...
EdwardBlake Posted July 6, 2015 Share Posted July 6, 2015 Mine is stamping brass with the same mark. Not sure it's enough of an issue to send the slide back to them. Link to comment Share on other sites More sharing options...
awfaxis Posted July 6, 2015 Author Share Posted July 6, 2015 If you're reloading your own brass, it "may" be. A few of my reused brass would hang up on the carousel on my Dillon because the gap was closing up a bit. Link to comment Share on other sites More sharing options...
CHA-LEE Posted July 6, 2015 Share Posted July 6, 2015 A buddy of mine that just got a .40 DVC Limited gun has the same breach face machining mark. This is sounding more like a CNC programing issue with cutting the slides wrong than a one off issue. STI Quality Control for the WIN....... Not.

DRed Posted May 22, 2016 Share Posted May 22, 2016 DVC 9 major same problem breach face not machined correctly And extractor problems. Will call them tomorrow Link to comment Share on other sites More sharing options...
Boxer1 Posted June 26, 2016 Share Posted June 26, 2016 I did not notice that on my DVC but I am going to start looking for that on all the STI slide I buy. I never would have guessed that would happen. Link to comment Share on other sites More sharing options...
Intel6 Posted June 27, 2016 Share Posted June 27, 2016 Never had this issue but it is not new for STI. Had a buddy whose Trojan did the same thing and he has had that for some time. This drives me nuts and would send it back as unacceptable. Link to comment Share on other sites More sharing options...
