Jaycwebb Posted November 9, 2019 Share Posted November 9, 2019 I used MBX for a few years with a Trubore and had zero issues, but they will not run in my new gun. The mags are great otherwise. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted November 9, 2019 Share Posted November 9, 2019 What's your new gun ? What does the MBX's do wrong in the new gun ? Any fix in sight ? Link to comment Share on other sites More sharing options...

Bought a used 2011 custom no mags came with it. Seller recommended mbx, as per the seller, works for him out the box. I was getting nose dives once or twice on a full mag. No fix for now, probably will need some more break ins, will be keep them loaded for few more days. Link to comment Share on other sites More sharing options...
Jaycwebb Posted November 10, 2019 Share Posted November 10, 2019 I had an issue similar to Joey. New custom gun with PT grip. Mix of old and new MBX mags. I would see 1-2 rounds per mag get caught up on the feed ramp and not get up into the chamber. I switched to the new STI mags and have had zero issues. All of the MBX mags run great with zero issues in my trubore I think the difference and the issue lay somewhere with the differences in how high the mags sit in the gun. Some how the mag release, release holes on the mag, and the ramp are just not in alignment with that configuration when I use MBX. When I compare the two it is clear the MBX mags sit a little lower and they do not present the bullet nose at the same angle. Link to comment Share on other sites More sharing options...

Hopefully, it will perform without any hiccups from now on. Im wondering if i should load tha mags again and leave them for few more days. Link to comment Share on other sites More sharing options...

If you do, please measure them (overall length, no load) now and then again after they're been compressed another couple of days, and let us know what you get.

Just the tube or the whole thing including the basepad? Noob question, what would be best to use to measure the mag?

Carry9shoot40 Posted November 14, 2019 Share Posted November 14, 2019 Be used Atlas tuned STI Gen 2 mags for years now. I recently bought a MBX 155 to try because I like the in between size for some stages. Out of the gate it would cause my gun to not go into battery. I replaced the guts with a gram follower and spring and haven’t had any issues since. The feed lips are not great but the mag runs so I don’t touch it.

Slide4949 Posted November 14, 2019 Share Posted November 14, 2019 about the feed lips, I bought a dawson precison mag tuning kit. Works great to re tune mags Link to comment Share on other sites More sharing options...

I apologize, i was so busy with work this past few days and didn't had the chance to measure the springs. I shot the South Florida hicap championship yesterday and did not have any problems with the mags. Link to comment Share on other sites More sharing options...
Hallz Posted November 23, 2019 Share Posted November 23, 2019 I was having the same issues with my 155’s and 38 SC,... I talked to Adrian (great knowledge and customer service!!) about a few things and after letting them sit for 2 weeks loaded, one runs 100% with zero changes. One was not 100%, I tried the GRAMS guts and It ran great, but have only got to try it for one stage so far. But that makes me believe the mag body works great. Probably just too much spring tension at first with the MBX when they are new. Afterwords I put the MBX guts back in and loaded it up again for a week. Hopefuly that one will be 100% from now on also. Link to comment Share on other sites More sharing options...
JJB05 Posted January 4, 2020 Share Posted January 4, 2020 New Open shooter...ordered a honcho and waiting for it....Getting ready to order MBX mags, can someone who shoots 9 major enlighten me on the usefulness of the 155mm mags? From what i see they hold 2 rounds less than the 170mm. I have heard they are easier for reloads, but having never tried them i cannot verify. I am thinking of 2-170's and 2 or 3 140's. Do i need 155? Thank you and don't mean to hijack this thread. Link to comment Share on other sites More sharing options...

I got rid of all my 140's as the 155 reloads are much easier and faster for me. Plus when replacing mag springs in 11 mags, it is easier to order all 170 springs.

I’ve tried loading with both over the off season and 155s are just easier to handle for me. Link to comment Share on other sites More sharing options...

As stated above, it is a little further from the magwell but without being as long as a 170. It is the perfect size. I have 5 of them.
