jrosario Posted December 8, 2015 Share Posted December 8, 2015 I run 11lb springs in my 3.3 titegroup loads and a 15lb on my 4.3 titegroup loads, all with 180gr rmr round nose Bullets and cci primers and a Zev extended firing pin. Never had an issue since I and I'm well passed 5,000 rounds. Link to comment Share on other sites More sharing options...

Dr Mitch Posted December 8, 2015 Share Posted December 8, 2015 Check the ejector. There is a number on the ejector. See if it is correct for .40S&W. Some guns have been shipped with the wrong ejector installed, 9mm in a .40 and vice versa. Not often, but it happens. Link to comment Share on other sites More sharing options...
obsessiveshooter Posted December 8, 2015 Author Share Posted December 8, 2015 I replaced the ejector with a lone wolf, no increase in reliability. But that was a good suggestion. Sent from my SM-N910V using Tapatalk Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted December 8, 2015 Share Posted December 8, 2015 I don't have a chrono, but this should make major. Very Bad Idea to shoot .40 major without a chrono. Lot to lose .... Link to comment Share on other sites More sharing options...
obsessiveshooter Posted December 8, 2015 Author Share Posted December 8, 2015 I know, I know. But the load is based on load data from the forums, and 4.7gr is the supposed max. And maybe Sandy Claws will bring me a chrono for Christmas. Sent from my SM-N910V using Tapatalk Link to comment Share on other sites More sharing options...
n0glock Posted December 9, 2015 Share Posted December 9, 2015 You went to the range no issues, possibly under stress at a match you are doing something different. Try having a friend watch/video you shoot they may see what is going on. shoot a drill or set up a stage that puts some pressure on you. Just a thought.

chs3131 Posted December 9, 2015 Share Posted December 9, 2015 Loads are too light for the RS. run a reduced RS spring. oh and convert to a single captured. Link to comment Share on other sites More sharing options...
obsessiveshooter Posted December 9, 2015 Author Share Posted December 9, 2015 I am running an uncaptured zev guide rod with a 15 lb ismi spring. Next match a fellow shooter offered to bring his chrono. I'm interested to see what the pf is. Sent from my SM-N910V using Tapatalk Link to comment Share on other sites More sharing options...
chs3131 Posted December 9, 2015 Share Posted December 9, 2015 I bet that will fix it. The non captured tends to actually give a little more tention compared to a captured Link to comment Share on other sites More sharing options...

obsessiveshooter Posted January 26, 2016 Author Share Posted January 26, 2016 I'm now running a 15lb captured spring on a jager guide rod. I have a chrono now and I've been shooting 190pf for the last yea!. My first two matches running my new load with 170pf ammo and the new guide rod/recoil spring I had zero malfunctions. That had an incredible effect on my match placement. This last match I shot I had another stovepipe jam like I used to have. I'm now going to try crimping my brass a little more. Maybe the lip of the brass is catching the back of the round that is about to be ejected and making it come off the ejector? I also ordered a 14lb and 13lg recoil spring to try. I've got a new resolve to figure out this problem, instead of quitting glock and getting a CZ TS. Link to comment Share on other sites More sharing options...
igolfat8 Posted January 26, 2016 Share Posted January 26, 2016 I suggest trying a lighter spring too. If your spring is too stout the slide never cycles all the way back and the springs rushes to close the slide too fast and sometimes closes before the shell is ejected causing a stove pipe.
