Jay,
You're welcome.
An additional factor with the DS is that toward the end of production Colt was recommending a return to the factory for a checkup after 3000 rounds of Plus P loads.
I like the little Dicks & carried one both off duty & as a backup in the early 80s, I just don't have unreasonable expectations of them & service is getting to be a real issue if needed.
If shot a lot, they'll run into timing issues eventually.
Not saying don't buy one, just understand what you're getting into.
