However, if someone would kindly measure the length of their LS mag (in inches or millimeters, doesn't matter) then multiply by 17 and divide by 14.5, we'll know the length of the plunger chamber.
The LS mag is 3 1/8" or 8cm.
So:
(3.125 * 17)/14.5 = 3.66" Or about 3 11/16"
Or:
(8 * 17)/14.5 = 9.38cm
Compare that to a Maverick which has a spring measured at 2.5" or 6.4cm approx.
