Sure.
Todd Jarrett Took a Box Stock Single Stack Para-Ordnance 1911 SSP (Model: PX745E B) and put 1000 Rounds through it as fast as he could without cleaning it, letting it cool down or anything.
In short it Functioned Flawlessly and got so hot he could barely stand to hold it or pull the trigger.
Then later (not in the video) after he finished, the Para-Ordnance crew that was there put another 4000 rounds through it (again without Cleaning it) and never had a single problem or Jam.
(Note that this was done with various different brands of ammo, and I am told by some that they even used quite a lot of reloads and Wolf ammo without any problems)

I think with that test Para Proved their Reliability in Spades.
