I just ordered my second 1911 last week. New at the SHOT show was a 1911 package that includes three slide/barrel/spring assemblies for 9mm, .40 S&W, and 10mm from Dan Wesson Firearms. Similar thier popular revolver pistol packs, a large blue hardcase holds everything in foam cutouts.
I wish I had a picture of the whole setup but its not on their website yet. I chatted with the DW guys at the show and asked them if the 10mm is just too much for the 1911 platform based on some of the Delta Elite stories I had heard. Bob Serva says that the Delta guns suffered from poor heat treatment and that he Gaurantees his pistols are up to the task.
Since I got my first 1911 I have fallen in love with the design and was trying to determine what 1911 I wanted next, but this 3 in 1 does it all. It should be in my hands in the next few weeks and I'll post pics and range reports as soon as I can.
Here is what the pistol packs look like, just squint and imagine a 1911 instead of a revolver.
