My son is in the Navy. One of the benefits his squadron receives is custom made firearms with all their squadron makings on it. They get these guns at a discounted price which is very nice. SIG usually added in range training and maintenance instruction.
The last one was a SIG 1911 in black with laser etching of the unit logo and motto. It's a very nice pistol and even nicer, he gave it to me.
The latest one is a beauty. A Kimber 1911 in stainless with wood grips, Novak style carry sights lowered and flared ejection port, beaver tail grip safety and the laser engraving. Take look for yourself.
