Rock Island 1911 Holsters for Concealed and Duty Carry

Rock Island 1911 holsters must account for the variations between compact, mid-size, and full-size configurations. Whether you carry the Rock Island 1911 A1 CS 3.5-inch, the MS 4.25-inch, or the FS 5-inch, Alien Gear Holsters provides custom-molded retention that secures the pistol’s steel frame and prevents unnecessary wear. 

Each holster shell is formed specifically for Rock Island Armory 1911 models, ensuring compatibility with the pistol’s slide dimensions, barrel length, and thumb safety.

Rock Island 1911 IWB Holster for Concealed Carry

A Cloak Tuck 3.5 IWB holster provides deep concealment for Rock Island 1911 handguns. The backing uses CoolVent™ neoprene for breathable comfort, while adjustable cant and ride height allow fine-tuning for appendix or strong-side carry. 

The slim profile reduces printing when carrying the Rock Island 1911 .45 ACP or 9mm variants, making it suitable for daily EDC.

OWB Rock Island 1911 Holsters for Range and Open Carry

The Cloak OWB Paddle Holster and Cloak Belt Holster offer stability and rapid access when carrying Rock Island 1911 pistols outside the waistband. 

Paddles allow easy on/off convenience, while belt-mounted holsters ride closer to the body for increased concealment under a jacket. Both designs accommodate extended shooting sessions, making them practical for training, competition, or duty carry.

Chest and Drop Leg Holsters for Rock Island 1911

When chest or thigh carry is preferred, our Cloak Swivel Drop Leg Holster and Chest Holster system position the Rock Island 1911 securely outside the waistband without limiting movement. 

The drop leg option distributes weight across the thigh with dual straps, while the chest holster keeps the pistol centerline, ideal for hiking, riding, or outdoor environments where waistband access is obstructed.

Hook & Loop Options for Rock Island 1911 Pistols

For modular and unconventional setups, hook & loop mounting holsters give the flexibility to attach your Rock Island 1911 inside vehicles, packs, or tactical panels. This option provides retention and accessibility while maintaining the pistol’s orientation in tight spaces where belt carry isn’t practical.

Rock Island 1911 A1 CS, FS, and MS Compatibility

  • Rock Island 1911 A1 CS 3.5-inch: Compact frame ideal for concealed carry, holsters account for shortened slide and reduced grip length.
  • Rock Island 1911 A1 MS 4.25-inch: Mid-size barrel and frame require holsters balanced for concealment and control.
  • Rock Island 1911 A1 FS 5-inch: Full-size frame chambered in .45 ACP or 10mm benefits from holsters with enhanced support and reinforced retention.

Secure Retention and Trigger Guard Protection

Every Rock Island 1911 holster includes a custom-molded shell that locks around the trigger guard. 

This prevents accidental discharge and ensures consistent draw stroke across carry methods. Adjustable retention screws allow shooters to set the level of draw resistance, tailoring holster performance to individual needs.

Comfort and Durability in Rock Island Armory Holsters

Alien Gear Holsters use a multi-layer design combining ballistic nylon, spring steel reinforcement, and neoprene padding. 

This construction keeps holsters durable under long-term use while maintaining comfort during all-day carry. The design also distributes weight evenly, which is especially important when carrying a heavy Rock Island 1911 FS model.

  • OWB Range Carry: Secure paddle or belt holsters for training and competition.
