Nanuk
Roomy NK-7 resin single-pistol hard case with PowerClaw latches, cubed foam, and IP67 protection.
The Nanuk 909 is the roomy alternative to a Pelican single-pistol case. Its NK-7 resin shell weighs 2.2 lb empty and carries a full IP67 waterproof, dustproof, and shockproof rating. The 11.4" x 7.0" x 3.68" interior runs larger than the Pelican 1170's, holding one handgun plus two single-stack or one double-stack magazine in cubed PEF foam.
Nanuk's PowerClaw latching system is the case's signature: an integrated compression latch that pulls the lid down for a positive seal and accepts a padlock for locked transport. The automatic purge valve equalizes cabin pressure changes during air travel, and the foam base plus soft lid foam sandwich the pistol from both sides.
At about $65 street, the 909 prices alongside the Pelican 1170 but gives you a noticeably larger interior, and it still weighs less than the bigger Pelican 1200. It is the better pick when you want more room in a travel case that locks and seals. Nanuk backs it with a lifetime warranty.
