1911 Frames
The 1911 frame is the foundational component of this iconic pistol, serving as the serialized receiver and the core structure for every other part. Your frame choice dictates the pistol's size, balance, and overall feel, making it critical for building a custom 1911 for competition, duty, or concealed carry.
Choosing Your Foundation
1911 frames are primarily defined by their size and material:
Sizes:
Government (Full-Size): The traditional 5-inch barrel length, offering maximum sight radius and excellent recoil absorption for stable shooting.
Commander (Compact): A popular 4.25-inch barrel option, balancing concealability with shootability.
Officer (Sub-compact): The smallest size, typically with a 3 to 3.5-inch barrel and shorter grip, optimized for maximum concealment.
Materials:
Steel (Carbon or Stainless): The classic choice, providing exceptional durability and added weight for superior recoil management. Steel frames are robust and contribute to a solid, traditional feel.
Aluminum Alloy: A lightweight alternative that significantly reduces the pistol's overall weight, making it highly desirable for everyday carry. While durable, it offers a different recoil impulse compared to steel.
Whether you're starting with an 80% receiver (which requires machining and adherence to local laws) or a fully machined, serialized frame (requiring FFL transfer), the quality and type of 1911 frame you choose will ultimately define the reliability, accuracy, and character of your custom pistol.
