Having recently sold my Springfield Armory MC Operator, I now have for sale a LEFT HANDED dark earth Safariland 6004 holster fitted for a railed M1911A1 with a Surefire X300. The holster is in like-new condition, having only seen minimal range time.
Included with the holster is a UBL-style belt loop adapter (a $15 value), if you like to run your holsters on a belt.
It’s a solid holster and in great condition. The belt loop adapter offers you the flexibility of mounting the platform on the thigh or belt.
From the Safariland site:
The Safariland 6004 tactical holster features the SLS rotating hood system which is so well suited for the tactical situations encountered today by police and military personnel. Since there is no snap, the tactical 6004 holster allows for a smoother single-motion draw and greater protection against attempted weapon takeaways and provides reliability in the unpredictable conditions that occur during tactical operations. The hood on the 6004 holster can only be released by being simultaneously pushed down and rotated forward and actually becomes more secure when upward force is applied. The Tactical Finish of the Safariland 6004 holster is rugged, protecting the gun in scrape, scratch and dent incidents. Molded sight track and soft orthopedic suede protect the gun’s sights and finish. A special feature of the Safariland 6004 tactical holster is the double leg strap and the leg shroud.

Tracking down a left-handed holster for a railed 1911 can be difficult at best. I had to wait several weeks for Safariland to special order this holster. This holster can be yours pending payment.
Average retail of holster and included belt loop adapter: $141.00
I’m asking: $80 OBO
I’m located in San Diego, CA and am willing to ship.
