From SIG SAUER . . .
Sig Sauer has determined that portions of Lot No. JDAR0815 of SIG SAUER 9MM, 115gr, Elite Ball, FMJ (SKU E9MMB1-50), may have powder charge variations that could result in a bullet remaining in the barrel (i.e., a bullet-in-bore obstruction). Firing a subsequent bullet into a bore obstruction could cause firearm damage, rendering the firearm inoperable and subjecting the shooter and bystanders to a risk of serious personal injury.
