HoMiE Posted March 14, 2009 Share Posted March 14, 2009 The ridges on the side of mag tube stop just about where round number 29 sits. When you try and put #30 in, guess what, it's too wide, and you found out what happens. I can't get more than 24 rounds in a 140mm tube with a 3mm tube, the more you try the more you are probably just spreading out the tube. I never load more than 23 in my 140 mags.

AWLAZS Posted March 14, 2009 Share Posted March 14, 2009 (edited) The tube needs to be modified to allow the follower to stay in position. I get 30 and 25 in 9mm Edited March 14, 2009 by AWLAZS Link to comment Share on other sites More sharing options...
RickyH Posted March 15, 2009 Author Share Posted March 15, 2009 My older SV mags are the ones that gets a round in the spring. i think it is because the center dosen't go all the way down. Link to comment Share on other sites More sharing options...

Just finished working on my number 2 mag. Worked on the rib and the lower dimensions of the tube and now it appears to be holding thirty without issue. It will load with one in the gun albeit a very tight fit. I don't usually do that because of the pressure on the grip but I hand cycled all the rounds without problem. Thanks again.

RickyH Posted March 15, 2009 Author Share Posted March 15, 2009 Boz1911 Do you have pic. of your mags now and how did you do it? Link to comment Share on other sites More sharing options...
outerlimits Posted March 15, 2009 Share Posted March 15, 2009 be careful mashing the side to extend the rib in on those expensive mags...unless you make a jig, it's touchy... Link to comment Share on other sites More sharing options...
boz1911 Posted March 15, 2009 Share Posted March 15, 2009 Boz1911 Do you have pic. of your mags now and how did you do it? It was pretty technical and I don't recommend this, but I actually cut a piece of wood larger in width than the mag and tapped it in the tube while at the same time squeezing the bottom section of the mag in a vice. I worked until I got the dimensions to match my number one mag. The number two mag was not quite as wide as the other mag. And no, I wasn't drinking.
