SMSI Posted May 14, 2012 Share Posted May 14, 2012 OK, this sounds like a stupid question, but how do you measure a hi cap sti/svi mag to determine whether 126, 140, 170 etc? From the bottom of the mag body to what? tallest point? Link to comment Share on other sites More sharing options...
gng4life Posted May 14, 2012 Share Posted May 14, 2012 yes, to the top of the rear feed lips... Link to comment Share on other sites More sharing options...
chirpy Posted May 14, 2012 Share Posted May 14, 2012 There is a drawing on the USPSA web site. Richard Link to comment Share on other sites More sharing options...
Jonathan Taliani Posted May 14, 2012 Share Posted May 14, 2012 (edited) Best bet is to pick up an EGW mag length gauge. Works like a charm. You may want to check with local shooters too, someone may have one you can borrow. Edited May 14, 2012 by Jonathan Taliani Link to comment Share on other sites More sharing options...
Flexmoney Posted May 14, 2012 Share Posted May 14, 2012 I don't think our opening poster is asking from a rules standpoint, but from a purchasing standpoint?? Link to comment Share on other sites More sharing options...
HoMiE Posted May 14, 2012 Share Posted May 14, 2012 To clarify, it should be from the bottom of the mag basepad to the rear of the feed lips. If you were to measure just the mag body (bare tube) it would be smaller. Link to comment Share on other sites More sharing options...
