For those wanting to buy a Colt Magnum Carry,
I submit the following, as an owner of a DS-II, its immediate predecessor.
One month after purchase, the mainspring breaks.
Two months after I bought it (a year and a half ago), the firing pin breaks.
Colt sends it back after many months, only this time, it is badly out of time.
I get a local to fix it, and all seems well, but the G-d Damned thing keeps breaking trigger springs every 100 or so rounds.
I also have a Python and Gold Cup that are less than stellar, and, in fact, have only owned one good Colt out of four purchased, including top of the line models.
I will note that the last spring I got from Colt was very strong and thick, so, perhaps, it won't sheer off one of the tabs (V shaped spring)
