I’ve owned and carried a couple of aluminum framed 1911s in the past—a 4” Sig, and a 3” Kimber. The Kimber ran flawlessly once it got past an initial defective slide stop issue. I don’t remember the exact round count before I sold it to another forum member, but it certainly wasn’t more than 1000 rounds. But during all but the first few rounds, it was perfect. I ditched the Sig after maybe less than 200 rounds because it was VERY unreliable, and the problem was unresponsive to different ammunition types, as well as a polishing the ramp, etc. Both guns had ramped bushingless barrels.Charles L.

The only notable problem I've heard of with an aluminum frame is the feed ramp. That's why most manufacturers, including DW, have gone to ramped barrels.
Chas.
But as far as range toys go, like you Charles, I preferred steel-framed 1911s, and still do.
