These are pre-Sept 1994 mfg. - probably doesn't matter at this point. But they have the (3) S logo on them "Sig Sauer and Son". Not sure if that means anything or not now. SigArms is selling new 20rnd 9mm mags now but these were purchased during the ban by me for $110 each.
With that said - they aren't "worth" $110 each so I expect to take a loss.
Excellent Condition - all three mags for $120 shipped
. One Magazine is now sold. Remaining two
mags for $40 each magazine + $3.85 shipping. Must be legal in your local area. Sorry no Paypal.
