open17 Posted August 30, 2015 Share Posted August 30, 2015 Just launched the build on a custom 9mm Open gun. Need some mags for it. Old style SV tubes are getting hard to find, and I'm kind of in the mindset "everything new" for the new gun. Did a search, checked FAQ's---(someone will be along in a minute with the link to the thread I missed ). Lots of info but nothing really up to date. So---given the current state of the art, if you were going to buy a set of new mags for an open gun, what would you get? Probably three 140's and one 170. New MBX complete? New SV complete? MBX tubes with *** springs and followers and *** basepads? SV tubes with *** springs and followers and *** basepads? Little more info. Not really interested in STI tubes and spacers. Whether the 170 holds 29 or 30 (or even 28) is not a big deal. I'm an old slow fat guy---plenty of time between arrays to hit a reload. Reliability trumps capacity. I have a very slight preference for straight on pads over slide on pads. Moving the mag catch notch a bit on a SV or shaving the bottom flanges on an MBX to fit a pad isn't a big deal. I've got a dandy milling machine. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted August 30, 2015 Share Posted August 30, 2015 The guy who won the Florida State Championship a few years ago uses only STI tubes (no spacers, since he shoots .38 super). Link to comment Share on other sites More sharing options...

Glk21C Posted August 30, 2015 Share Posted August 30, 2015 SV or SPS tubes with grams internals and bp's will get u 28-29 rnds and be reliable. as long as your frame has the proper bevel along the bottom where the top of the magazine would be you'll have no trouble with new style SV mags, especially since you are having the gun built. or just try the mbx's; adrian is working hard to make a good product Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 30, 2015 Share Posted August 30, 2015 Hello: I am testing a STI 140mm tube right now with Dawson follower and ISMI spring with Dawson base pad. It uses no spacers and is feeding 100% so far(less than 500 rounds). I will try a 170mm as soon as I can get my hands on some. I have used STI 170mm tubes before and modified the bottom, and used Grams guts and base pads. They worked fine but took a bit of work to make work. Once done they worked 100% and as far as I know are still going strong. Thanks, Eric Link to comment Share on other sites More sharing options...
blairmckenzie1 Posted August 30, 2015 Share Posted August 30, 2015 sti tubes, grams guts, taran's pads and hardy spacers. i know it isnt the newest but its been super reliable with no tuning for me. Link to comment Share on other sites More sharing options...
Nowind0 Posted September 6, 2015 Share Posted September 6, 2015 Sorry for hijacking the thread, but is there any performance difference in the plastic vs. metal spacers? Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted September 6, 2015 Share Posted September 6, 2015 any performance difference in the plastic vs. metal spacers? I run both and haven't seen any difference. Link to comment Share on other sites More sharing options...
orangeman711 Posted September 6, 2015 Share Posted September 6, 2015 I've been running complete MBX since they came out and have had no problems what so ever. They run 100% in both my STI and SV. Link to comment Share on other sites More sharing options...

scooterj Posted September 6, 2015 Share Posted September 6, 2015 (edited) 30 rounds of 38 Super with no issues In my MBX 170mm. Supercomp or 9mm gives a little more room. This is with the new heavier spring and follower with shelf b Edited September 6, 2015 by scooterj Link to comment Share on other sites More sharing options...
Flatland Shooter Posted September 6, 2015 Share Posted September 6, 2015 This thread got me to look at the MBX website. It indicates their tubes are designed to work with MBX internals. Has anyone tried other vendors followers and springs with these tubes? Did they require modification? Thanks. Bill Link to comment Share on other sites More sharing options...

andersonj55126 Posted September 8, 2015 Share Posted September 8, 2015 MBX 170 with latest follower and spring have been 100% MBX 140 with old spring and follower have also been 100% Link to comment Share on other sites More sharing options...

Has anyone tried other vendors followers and springs with these tubes? Did they require modification? Thanks. Bill If the MBX mags work as advertised (expecially without 9mm spacers) why would you want to try other internals. Just saying.... The price is right too. The only mags I know of that run 100% without spacers are the old style SV and you pay a small fortune for those in good shape. Having said, I have not tried MBX as I have the old style SV mags and they run 38/9 100% with Bevan's stuff. Link to comment Share on other sites More sharing options...

The only reason I asked is I have a small stockpile of Grams followers and springs plus extra Dawson base pads. I use the old style SV mags for matches and considered some MBX tubes for practice.

Powder Monkey Posted September 29, 2015 Share Posted September 29, 2015 I just got an MBX mag today. Can anyone give me some guidance on how to remove the base pad? I don't want to damage something as finger pressure does not seem to do the job. Link to comment Share on other sites More sharing options...

ogiebb Posted September 29, 2015 Share Posted September 29, 2015 I have tried STI,MBX and SV new and old tubes... the best that ran a 100% for me were old style SV Tubes with TTI guts and pads ran reliable and almost no need for tuning in all my 40sw and 9mm.

Aircooled6racer Posted September 29, 2015 Share Posted September 29, 2015 Hello: I like the old style SVI tubes as well for 9mm. Feed lips stay tuned and they simply just work. I have been using the same big stick for over 6 years and have not changed anything in it. Same follower and spring but have changed out the base pads a couple of times but have gone back to the Dawson ones for good. Thanks, Eric Link to comment Share on other sites More sharing options...
