The boys from Milcomp visited us in order to test the APC556 PDW. Here is their review:
5.11 Tactical Series bag Single pistol
Perfect pistol portage: Our Single Pistol Case measures 23 x 28 cm. and is made from 1050D nylon with lockable YKK® zippers for security. An internal zippered pocket holds your pistol separate from magazines. A WriteBar makes it easy to label the pistol case with a marker.
