All but Colt are backlogged at least a year.
Colt can still do some work on them, but Colt is running out of parts & has not ordered any in a long time. Quite possibly might never do so again, they're not obligated to support long discontinued models forever.

How soon you wear a DS out, or how soon it may need work, depends on how much you shoot & what you shoot.
Not recommended for lots of +P loads.
