The 1911 has become the Harley Davidson of the pistol world. You can get extended slide stops, beavertails, custom fit bushings, adjustable triggers, guide rods, this barrel length, that barrel length, curb feelers, mud flaps, etc. to your hearts content, all of which deviate from the good ole John Moses Browning design. Modern manufacturing with tighter tolerances may in some cases contribute to lack of reliability. Compound this with the fact that maunfacturers have continually shortened or changed the original platform to accomodate easier concealed carry or provide new and improved features, and you are walking a fine line with reliability.
No doubt this is the sloppiest of your collection with respect to fit, but probably the most reliable.The Annoyed Man wrote:1943 Ithaca that was my dad's sidearm in WW2: Runs like a champ. Digests everything. Guaranteed MOD (Minute of Door) accuracy. Worst sights in the world.
I have a Combat Commander that has the Colt rattle but it has yet to fail to function. It even has one or two of the Series 80 flaws but I wouldn't consider trading it. On the other hand, I recently fit a Colt slide to a Caspain frame. It slides like it is on ball bearings with absolutely no perceptable play. I haven't finished the pistol yet, but this one will have to prove itself before I consider carrying it.
