I believe you can get the Remington R1 in .40 S&W as well.

Side note, one of my bullseye pistols, for a time, was a police trade-in 1911, a Springfield Loaded with (ha!) fixed sights. I performed the following in order to ready it for competition:

(1) Place ammunition inside of it.

I won a bit with that gun, and later used the lower for a .22LR conversion that also did a bit of winning, before I built a dedicated lower.

I don't wholly subscribe to the loose=reliable theory, but there's no doubt some fitting methods result in a very tight gun that isn't terribly reliable (and also not accurate for very long in 1911 terms). I've have found that you can have a "loose" gun that shoots very well, and a "tight" gun that's perfectly reliable.

After all, custom bullseye guns are accurate by anyone's definition, but national competitors expect them to run just fine in wind-blown dust and driving rainstorms.
