Although when would u ever need to reload 20 rounds ? Doesnt USPSA still have a 32 round max stage count ? I mean if u are starting with 21 rounds, and need to reload another 20 rounds,, ur stage is probably shot. Granted I havent followed the game in a while, so maybe things have changed. Just curious. Normally if everything runs you're correct, but there's always the chance a mag could malfunction early in the stage. Stage may get trashed and I'll never win the Cadillac, but I like to finish the stages. Plus the biggest handicap is the 22 round stages where the 9mm doesn't need to reload at all. As I said earlier in this thread, this is not the best caliber for CO. I've always liked this gun. It started life as a TTI G34 and I use that slide on this gun as my backup for my 3gun 2011. I tried 40 lite in Production a few years back with the G34 slide. I loved the low recoil and the accuracy just gets better as you go down in PF. I'm using that same load for this CO gun and it's a tack driver at 28 yards. A zone hits are stupid easy.

Harlow Posted December 4, 2018 Share Posted December 4, 2018 I'm getting 20 not reloadable in one of my tti basepads with factory guts. 19 reloadable in another tti/factory guts. And 19 reloadable with a brass Taylor freelance and factory guts. Link to comment Share on other sites More sharing options...
72stick Posted December 8, 2018 Author Share Posted December 8, 2018 (edited) I pulled the trigger on buying two MBX 140mm extensions and springs from Shootersconnection. I also bought two new G22/35 mags for the conversion. I trimmed and smoothed the transition areas in the 1stmag tube and tuned the follower edges. I had a lot of trouble getting the first mag with the MBX extension and spring to load more than 18 rounds. After battling with this mag for an hour with no improvement, I took a break. I called SC and the tech suggested what I’d already done. I tried to find a customer support number for MBX. All I could find was an email address when I selected “contact us” from their website. I called SC again and asked if they had a number for MBX. Nope, MBX only accepts email. SC offered to email them for me. They asked MBX if there’s anything else to do that would help me load the full 20 rounds and cc: me. I went back to the bench and tried loading the mag and extension with the factory Glock spring. As I got to the 18th round, I felt the follower jump. Even though I had removed material on the follower and rounded the edges, it was still hanging on the edge of the extension. I removed the follower and tuned it some more, actually a lot more than I did for either the Dawson or Taylor Freelance extensions. I put the mag back together with the Glock spring and this time it took 20 rounds. It actually had some room to compress the Glock spring. I crossed my fingers and put the MBX spring in and loaded the mag. It took all 20 rounds using my maglula and it also had a little room to compress the spring. I removed the 20thround and was able to re-insert the round with my thumb. Knowing how much material has to be removed from the follower, the other mag was a snap assembling with the MBX extension and spring. I’m going to let them both set overnight fully loaded with 20 rounds. I’m hoping tomorrow these mags will both be 20 reloadable. Woohoo!

72stick Posted December 8, 2018 Author Share Posted December 8, 2018 (edited) Holy Crap! I checked the mags and I can get 21 in them. It's tight, but they take 21. I can't wait to test these mags with 20 rounds reloadable and do some drills. Edited December 8, 2018 by 72stick Link to comment Share on other sites More sharing options...
Southpaw Posted December 9, 2018 Share Posted December 9, 2018 (edited) Shows how much I know haha. Do you have access to a mag gauge to make sure they fit? Edited December 9, 2018 by Southpaw Link to comment Share on other sites More sharing options...

Would it be possible to share a photo of how much you modified followers compared to stock? Link to comment Share on other sites More sharing options...
72stick Posted December 10, 2018 Author Share Posted December 10, 2018 I can do that if you would like, but I'll add that I've been in contact with Adrian at MBX. He was very responsive to my concerns and surprised I had to remove that much material to get the mag to accept 21 rounds. I'm not sure why mine needed so much tuning. I would suggest before you remove as much material as I did you test fit the follower. Adrian said, normally all that is needed is "cleaning up the edge and excessive plastic inside the tube let us know if u have any other concerns or issues". So, maybe the latest version of the Glock 22/35 .40 SW follower is a little different. Link to comment Share on other sites More sharing options...
