jamesb Posted December 23, 2011 Share Posted December 23, 2011 (edited) So I got my 9mm Witness in yesterday and it is awesome. Upon cleaning and re-oiling the bull barrel I noticed on the right side of the feed ramp, towards the top right side where it meets the barrel chamber there is what looks like a burr, but it looks very clean cut, almost like it is supposed to be there. I tested sliding a round up the ramp into the chamber and from what I can tell the round never once touches it. It also doesn't look like the extractor touchs it either. Would you leave it or just carefully smooth it out? Nothing touches it and it doesn't look like it will affect anything at all. It is more on the side wall of the feed ramp if you call it that. You notice it when looking at it directly from the right side like my drawing. Anyone else's like that? I'll get a photo after work, but for now this is a nice drawing of what I mean.

Mo Hepworth Posted December 23, 2011 Share Posted December 23, 2011 have you shot rounds thru it yet? If you have no issues with feeding than leave it alone... Link to comment Share on other sites More sharing options...
Nealio Posted December 23, 2011 Share Posted December 23, 2011 Is it a burr or is it a notch? Link to comment Share on other sites More sharing options...
jamesb Posted December 23, 2011 Author Share Posted December 23, 2011 No rounds through it yet. It doesn't look like it will interfere at all with the round, but I don't think it should be there. You can see how the other side is. It looks like they went to far on the feed ramp and created that slight notch. I'm going to take it down very lightly.

bikerburgess Posted December 23, 2011 Share Posted December 23, 2011 It looks to me like when they fit the barrel the ledge at the bottom of the extractor gruve hit on the slide so they rounded it over with a file but didn't blent the notch it created in the side of the feed ramp. you could file it down without hurting anything but I dont think it will hurt anything to leave it either.

jamesb Posted December 23, 2011 Author Share Posted December 23, 2011 (edited) Thanks Mike, I carefully took a 1000 grit and 600 grit sanding stone to it. I knocked down the notch most of the way, but it is just the slightest bit left. I think it is going to be fine so i'm not going to mess with it any more. Another thing I somehow did, when tightening the front set screw for the sight, the screw actually started to go through the slide. There must be very little metal between the setscrew and barrel. It went through enough that I couldn't insert the barrel again. I backed it off a hair and locktited it and it's fine now except for the slight indentation when you look at the slide from the inside. I found that a bit odd. It is barely noticeable if you slide your finger in there. The macro lens makes it look way worse than it is.

david s Posted December 24, 2011 Share Posted December 24, 2011 The Macro lens is pretty cool! A picture is worth a thousand words! I hope everyone has a good Christmas!! Link to comment Share on other sites More sharing options...
Barry Davis Posted January 2, 2012 Share Posted January 2, 2012 My 9mm Match Elite has the exact same burr in the exact same place. I have about 10K rounds thru mine without any issues whatsoever. Link to comment Share on other sites More sharing options...
