Nick_shoots_fast Posted December 16, 2019 Share Posted December 16, 2019 I’m pretty sure this is spring related but I want to throw it out there. I literally used this mag 4 times max and it kept jamming up on me at a match. The first time it did it I thought I was riding the slide release and locked the gun up. The second time I did it, it was the mags fault. The top round didn’t pop up and was jammed up just below my feed ramp. The mag was tuned by myself before hand at .370 in the rear and .390ish in the front. This is what I have all my mbx mags at and has always worked. When I was unloading my mags at the end of the day I noticed that the spring pressure was really weak about half way thru the mag. The rounds were also very slowly “pooping up” which means it’s a spring issue. This was odd to me seeing that the mag was practically brand new. I got this mag so I can load 21+1 at the line but was shocked when problems came up. When I take the base pad off, I have 3 coils showing past the end of the mag. I got this mag as a complete TTI system. TTI spring, TTI follower and TTI base pad on the new STI mags. Anyone else confirm my issue? Pissed that I have to buy a brand new spring for my brand new magazine! Link to comment Share on other sites More sharing options...
zzt Posted December 16, 2019 Share Posted December 16, 2019 email TTI and explain the problem with your new mag. They will make it right. However, they may not get back to you for a week or so, because of problems associated with thr CA wild fires. BTW, it sound more like a mag body problem, not a spring.

Why hasn’t anyone came out with a reliable magazine?! They have. My MBX mags ran flawlessly for the last four seasons. I was perfectly happy with an easily reloadable 20 +1 in 40sw. Same with 25 and 29 in my 9mm mags. I have never understood the obsession with getting one extra round in a mag, especially if it affects reliability. I literally cannot think of a stage I've shot that I would shoot differently if I could start with 21 +1, or 30 +1. I'm more likely to underload a mag so I can drop it with only 3-4 rounds left in it. Link to comment Share on other sites More sharing options...

I told the lady I was gonna try a few things out first. She said if that doesn’t work they will fix it for free. Glad to see there’s companies that will fix their own problems.

Ming the Merciless Posted December 17, 2019 Share Posted December 17, 2019 Load the mag to capacity and leave it loaded for a couple of days so the spring will take a set, then it will probably work OK. Link to comment Share on other sites More sharing options...
TRPOperator Posted December 17, 2019 Share Posted December 17, 2019 I run TTI everything is all my mags. It could be a follower drag issue. Check the follower and if it is the super thin follower, check to see that the small point that is for the slide catch is not dragging. To make sure I dont have that issue, I shave mine down. I have ever only had 1 mag that did the same. With about 8 rounds left in the mag it would drag. I shaved the small tab off and have never had another issue.

dthomas1003 Posted December 17, 2019 Share Posted December 17, 2019 Check out the mag tuning videos from Atlas Gunworks. Pay particular attention to the one tuning the transition from double stack to single stack. This area being too wide can induce the issues with the rounds being to loose.
