Hello,

 

Need to put together a 140mm SV magazine for maximum capacity in Open 9mm Major. I am using Grams internals, what basepad do you recommend? How many rounds reloadable?

 

Thanks

Since 140’s in Open don’t have to fit a gauge you can pretty much put anything you want on it. Probably a 7mm TTI since that’s what I run and know it gets me 22 reloadable in STI tubes

I have 4 of the old style SV 38/9 140 mags with Grams springs and followers and Grams 11 mm base pads for my 9 major open gun. I get 25 rounds to start in them if I use the regular 11 coil Grams spring and 24 rounds reloadable, if I use a longer Grams 13 coil spring. The 11 coil springs have been reliable, but the 13 coil springs give an extra measure of feeding force in that regard, although down a round. I have the 13 coil springs installed now and down the one round has not made much difference in my experience.

Anybody find taran followers to give problems bs grams? I grabbed a couple tartan followers when they were on sale. Seem to be similar Just curious if taran are worse than grams. 

All I run are TTI springs and followers in my MBX mags, zero failures. I DO run Grams guts in my STI Limited mags though.

This thread got me thinking about my 140 9mm open mags. I’ve been using Dawson bases & Grams guts, getting 23 just by slapping it all together. I just got a Cheely E2 grip, and was concerned the Dawson’s wouldn’t fit, so I swapped some Arredondo extended bases onto them and I now get 25. The one Grams 11mm base I have gave me 24.
