STI Posted October 27, 2005 Share Posted October 27, 2005 Help. I have a new STI open gun and while training the other night I was doing Bill Drills. When I went to clear the gun after firing the 6th shot I found the gun had not extracted the last empty case. What I’m saying is there were 6 holes in the target and 1 empty case jammed in the gun. There is no way I can retract the slide more than 2.5-3 mm. Ie far enough so the disconnector operates but that’s it. I cannot obviously get the slide back far enough to remove the slide stop. Now if I cock the hammer and then for want of a better description shake the frame the slide moves back and forth the 2-3mm but there appears to be no spring tension on the slide and the barrel stays locked up in the slide. Any Ideas I'll try to post pics later when I get home Link to comment Share on other sites More sharing options...
Scout454 Posted October 27, 2005 Share Posted October 27, 2005 The lug may be sheared off of the barrel. Link to comment Share on other sites More sharing options...
STI Posted October 27, 2005 Author Share Posted October 27, 2005 The lug may be sheared off of the barrel. the *&%&%* gun has only fired 250 rounds, only arrived last week. If this is the case how often does it happen?? Heres a pic but gun now wears a CMORE but dont have pic of it yet Link to comment Share on other sites More sharing options...
Merlin Orr Posted October 27, 2005 Share Posted October 27, 2005 I have fired some ammo that was loaded to long for a short throated gun and had a problem that sounds just like what you describe. I tried clearing it by holding the slide and striking the grip - forward - a number (a bunch of times) with no sucess. I let my gunsmith buddy Dwayne have it and - after a few more of the same he cleared the gun in the same manner I was attempting. I would Not have believed the long loaded round was the problem... but it was. Link to comment Share on other sites More sharing options...

I would Not have believed the long loaded round was the problem... but it was. Just to clarify the stuck case is a fired empty NOT a live round, fired OK and there were 6 holes in the target, equal to number fired. Also last shot was not louder or quieter than the previous 5. I suspect mechanical failure of some sort as primers on all the other fired cases are not showing pressure signs. Load is 9gn 3N38 behind 124gn CMP projectile. Problem is how to get the slide /barrel off to investigate, barrel is not unlocking from slide, not enough movement methinks but cheers for the replys guys appreciated Link to comment Share on other sites More sharing options...
Matt Cheely Posted October 27, 2005 Share Posted October 27, 2005 If the gun fired the 6th round and loaded normally, it is possible the the stuck round is too long of a case or some such problem. I've had it happen before. Can you try putting a squib rod down the barrel to help knock out the case? Link to comment Share on other sites More sharing options...
Merlin Orr Posted October 27, 2005 Share Posted October 27, 2005 Another "DUH" moment for me... You only stated that TWICE in your post. Link to comment Share on other sites More sharing options...
STI Posted October 27, 2005 Author Share Posted October 27, 2005 Another "DUH" moment for me... You only stated that TWICE in your post. No Worries happens to all of us especially me. Yes I have tried to gently knock it out with a squib rod but no movement Link to comment Share on other sites More sharing options...
Harmon Posted October 27, 2005 Share Posted October 27, 2005 (edited) cock the gun, move the slide as far rearward as you can, then push down on the barrel through the ejector port. this should allow barrel to drop out of lug engagement...hopefully. oncce the barrel is unlocked from the slide, the slide should be free to travel rearward... if when the slide moves rearward, the barrel drops like it was being pulled from the locking lugs by the link and stops moving rearward when the barrels lower lug contacts the frame, what you have is a stuck case.. with the guns slide pulled as far to the rear as you can, insert wooden dowel into muzzle and tap the case out with a mallet. or send it to gunsmith Edited October 27, 2005 by harmongreer Link to comment Share on other sites More sharing options...

I have tried what you suggest and cannot get the barrel to "unlock" at all ie no movement. I was really mainly wondering what could cause such a immovable lock up of slide and barrel. Cheers for all the advice though Link to comment Share on other sites More sharing options...
Icchan Posted October 27, 2005 Share Posted October 27, 2005 Good luck, let us know what they say. Could be lugs, link, or case; hope it's just the case! Link to comment Share on other sites More sharing options...
infinity Posted October 27, 2005 Share Posted October 27, 2005 that happened on my Standard STI eventually the culprit was the barrel link..my smith had to replace it...now it's ok. hope this helps. Link to comment Share on other sites More sharing options...
STI Posted October 27, 2005 Author Share Posted October 27, 2005 Thanks for all your input guys, I'll let you know how it turns out For the record the gun is in 38SC, has STI frame, barrel and slide, Konig hammer, C&S Sear and Disconnector, Comonoli Guide Rod and Underported Comp designed and Built by the manufacturing Gunsmith. He also built my STD gun which I have since sold to buy this. Heres a pic of the finished article with C-More instead of JPoint, yes it is heavy but I'm not small either!!!!!!!!!!

STI Posted October 27, 2005 Author Share Posted October 27, 2005 can u share pics of ur comp? thanks btw, who's ur smith, does he have a website? thanks again!!Regards, infinity Infinity Unfortunatly my gunsmith does not have a website and I doubt you will have heard of him as we both reside outside the USA, way down in New Zealand infact. Complete gun cost $5850 New Zealand Dollars approx, $1NZ=.68US cents. Cost was approx same as STI Grandmaster. As for the comp, Alan tells me its machined from a solid piece of barstock and takes about 2 days to make as he uses a manual mill! Each comp is custom built for each gun and he will customise it further if you want something different. Cost for the comp is $550NZ Dollars + fitting, I'll let you work out the conversion to Real Money but I think maybe approx $350US. As for Pictures I'll Post some but you'll have to wait until the gun comes back in its unjammed and working state!!!! May be next week. Link to comment Share on other sites More sharing options...
Harmon Posted October 27, 2005 Share Posted October 27, 2005 fear its going to be a broken barrel link by the way it sounds. Link to comment Share on other sites More sharing options...

surfmaster Posted October 27, 2005 Share Posted October 27, 2005 Why did you switch from the JPoint to the C-More? Was it harder to track the JPoint? Please advise. Thanks. Link to comment Share on other sites More sharing options...
STI Posted October 27, 2005 Author Share Posted October 27, 2005 Why did you switch from the JPoint to the C-More? Was it harder to track the JPoint? Please advise. Thanks. JPoint was absolutly fantastic but I really wanted it for a saddle mount on my AR. Swapped to C-More for pistol as I got one cheap, Also C-Mores are readilly availible in my country where as JPoints are not so If my C-More fails I can get one tomorrow but have to have a JPoint shipped from the USA 3-4 weeks Link to comment Share on other sites More sharing options...
STI Posted October 28, 2005 Author Share Posted October 28, 2005 Well good news, gun is fixed. Problem was with the Underport Comp system, I asked for a threaded plug so I can clean out the Under Port. This for whatever reason had backed out far enough to contact the guide rod thus causing my problem. Gunsmith managed to get the slide / barrel off. Cut the thread in the comp deeper . Reinstalled the plug with a different type of locking compound. Shortened the guide rod by 2mm And shipped it back. Hope to get it back tomorrow, test it in the weekend and If others still want photos I’ll post some next week. Thanks for all the advice Mike Link to comment Share on other sites More sharing options...

STI Posted October 28, 2005 Author Share Posted October 28, 2005 Difficult to explain but I'll try Directly in front of the barrel at the very begining of the comp there is a hole which leads to a chamber under the comp proper, this in turn leads to two small exit holes in the front of the comp, sooo the some exhaust gas is deflected down under and then up while the rest goes thru the normal top part of the comp. maybe someone else can explain it better. Theory is that gun shoots "flatter" and certainly seems the case in my limited experience. As I said I'll try and post some pic's next week of the comp if anyones interested? A pictures woth 1000 words as they say Link to comment Share on other sites More sharing options...
mcoliver Posted October 28, 2005 Share Posted October 28, 2005 Hmmm...could be the same as a Limcat turbocomp except that the little front holes blow up instead. Link to comment Share on other sites More sharing options...
STI Posted October 28, 2005 Author Share Posted October 28, 2005 Hmmm...could be the same as a Limcat turbocomp except that the little front holes blow up instead. Yup looks very similar although I've never seen / shot or even held onto a Limcat of any sort. Way down here in the bottom of the world good things never seem to come in a hurry or great numbers. Hell NZ only has 3000 B Endorsed (Pistol Shooters) in total, (all firearms users must hold a current firearms licence or be under the direct supervision of someone who does) and of that number probably 600 shoot IPSC regularly. The numbers are so small my gunsmith says he could never make a full time living from it. However I digress Mike Link to comment Share on other sites More sharing options...
infinity Posted October 28, 2005 Share Posted October 28, 2005 mco, what if the ports are on the side would it make it shoot flatter? Link to comment Share on other sites More sharing options...
