CrashDodson Posted December 20, 2016 Share Posted December 20, 2016 I have 8 svi mags. 4 are old style 4 are new style. All of them have different feed lip dimensions. The Enos SV mag post, dawsons video, the freedom gunworks tutorial all have different feed lip recommendations. What is the current trend in feed lip dimensions for SVI mags? Mag body dimensions?

Glk21C Posted December 20, 2016 Share Posted December 20, 2016 You're best bet is to ask SVI for that dimension per caliber. Link to comment Share on other sites More sharing options...
CrashDodson Posted December 22, 2016 Author Share Posted December 22, 2016 So SV says they use a .430 pin gauge....but I havent confirmed yet exactly what part of the mag they are measuring with the pin gauge. .430 width on the feed lips seems a little much.

Sandbagger123 Posted December 22, 2016 Share Posted December 22, 2016 (edited) i have 2 140 and 1 170 9mm mag. the two 140 are .312/326 and .308/316. the 170 is .350/351. Never had a issue with them feeding . i have 3 140mm 40 mags and they are 370/386 .374/380 ..380/383. same thing never had a problem with them be careful adjusting them as the metal in older sV mags seems thicker than my STI mags. they will split the rear seam before bending Edited December 22, 2016 by Sandbagger123 Link to comment Share on other sites More sharing options...
Shmella Posted December 26, 2016 Share Posted December 26, 2016 I have two old style 9/38 140's that I recently acquired and the feed lips seemed extremely tight. .300 front to back and one was .297 front to back. I adjusted my sti Feed lips following the Dawson DVD. These are so tight (comparing to the Sti mags) I'm afraid to try and work them. After reading this post I'm going to just try them and see how they work. So is this normal and the general consensus is to just leave them alone?

CrashDodson Posted January 8, 2017 Author Share Posted January 8, 2017 I adjusted the mags but am having trouble with some rounds not pointed high enough. They stick on the feed ramp, like going straight into the ramp instead of up. Which part of the feed lip should be adjusted to troubleshoot this?

Glk21C Posted January 8, 2017 Share Posted January 8, 2017 The double stack to single stack transition is the most likely culprit BUT you can chk to make sure the feed lip dimensions are at a min. Equal across the opening or maybe slightly wider towards the frt. If that is all ok that transition I mentioned can be adjusted by squeezing that transition a little at a time, making sure to keep the mag square. Squeezing won't be easy as those mags are really tough. Link to comment Share on other sites More sharing options...
