mcmmotorsports Posted September 27, 2020 Share Posted September 27, 2020 Hello everyone. Hopefully you can help me with my issue. This TSO has a little over 1,000 rounds through it. Same with all five of my magazines. My last match, I had 7 FTF malfunctions. I thought it was an OAL issue, so I lengthened the rounds to 1.135 from 1.126. That didn’t help as it happened today at the range and I am able to recreate the issue, at home, by racking the slide with rounds in the magazine. Other than a mag catch issue, could the grams followers be an issue? Video: Link to comment Share on other sites More sharing options...
Lowsc3 Posted September 28, 2020 Share Posted September 28, 2020 How many rounds are you putting in the mag? I run 20 in my .40 i could fit 21 but i think its to tight of a fit to have the slide cycle properly. Also is it with just the one mag or all of them?

Lowsc3 Posted September 28, 2020 Share Posted September 28, 2020 I had this issue before when the gun was fairly new. Usually a push on the slide or rack of the slide and that was it. I'm roughly 5 k rounds now and it hasn't happened for a long time I chalked it up to some break in. Link to comment Share on other sites More sharing options...
muncie21 Posted September 28, 2020 Share Posted September 28, 2020 I run grams guts in all my TSO mags (.40 & 9mm) and don't have the issue you have. Couple of things I'd checkout before changing mags/followers. 1) Remove the magwell and grips and see if this changes anything. 2) With slide locked back, insert a loaded mag and see if the shell case is hitting the ejector, preventing the mag from full seating 3) Check mag release to see if there are any burrs or irregularities that would prevent the mag from seating correctly. 4) If this is a newer TSO with the removable mag release paddle (like the S2) check to see if the paddle making contact with anything Link to comment Share on other sites More sharing options...
GeneBray Posted September 28, 2020 Share Posted September 28, 2020 Clean the breech face particularly the left side where the rim resta. Remove extractor and clean it and Spring and slot for extractor. Ensure no issues with recoil spring and it is the right poundage. Link to comment Share on other sites More sharing options...
IF788 Posted September 28, 2020 Share Posted September 28, 2020 what recoil spring are you using? did you mess with the extractor / extractor spring at all? CZ like SHORT or Sammy spec / factory rounds. lengthening them will only make issues worse. CZ cannot shoot lengths 2011s can, they are notorious for SHORT rounds only.

Superkaratemonkeyfighter Posted September 28, 2020 Share Posted September 28, 2020 It’s almost like the mag isn't seated all the way. Maybe your bumping the mag release just enough so the mag backs out slightly. Is it your first mag of the stage ? or after a reload ? Link to comment Share on other sites More sharing options...

Pretty sure we have isolated it to a bullet profile issue The PMC and Black load fine. The Blue is giving me fits. Link to comment Share on other sites More sharing options...

If this is an issue with a single bullet profile (my previous assumption was this occurred with all ammo) it's going to be OAL or bullet geometry related, almost guaranteed, as case, mags and gun geometry are all pretty much constants. Since there are lots of folks shooting blue bullets in TSO's my wager would be on the OAL. I don't use blue, so can't provide any guidance there. My BBI loads are around 1.12-1.13.

muncie21 Posted September 28, 2020 Share Posted September 28, 2020 I have some 1.15 BBI rounds (for my 2011) that I was able to hand cycle through my TSO. I didn't remove the barrel to see if the rounds would plunk correctly, but they did hand cycle with no problem. Why not create a few dummy rounds of each length (shorter/longer) and see what works.

Superkaratemonkeyfighter Posted September 28, 2020 Share Posted September 28, 2020 Glade you got it figured out. Cant really help. I find where the bullet hits the lands and back it off .005 or so. Never had to deal with that. Honestly I’m not sure that’s it but figure that out and see if returns. Link to comment Share on other sites More sharing options...
BLUEPSTU Posted September 29, 2020 Share Posted September 29, 2020 My guess would be shooter error. I think you are just trying to find an excuse to keep shooting a gun with an optic. Link to comment Share on other sites More sharing options...

I had a couple FTF issues w the CZCustom 10 coil and the CZC base pad at the range. Didn’t want to mess with it so ordered a grams and use the stock spring w CZC base pads in 2 of my mags. So far no issues (knock on wood). Curious to hear what ends up fixing your FTF. Good luck. Link to comment Share on other sites More sharing options...
