1911 School, Feeding Part 1 of 3

In order to effect a better understanding of the dimensions and conditions critical to reliable feeding in the 1911 pistol, I thought this might be a good idea to go into more detail than the average magazine article. The first critical spec is feed and barrel ramp angles. The feed ramp is ideally 31-31.5 degrees […]

The MIM in 1911 Bugaboo

The MIM in 1911 Bugaboo The first pistol that I noticed containing MIM parts was an early 1991A1 Colt. I saw it again in another Colt bought just a matter of weeks later. I bought the pistols specifically for beater duty, and I’ve beat’em long and hard ever since. The pair is approaching 400,000 rounds, […]
