Dan Wesson Heritage Stainless.
I've had good luck with 1911s so far. The DW has about 600-700 rds through it with no hiccups. The RO Elite has about 400 with no issues. Both passed the 10-8 test out of the box with stock mags.
This isn't a huge round count compared to the world of service pistols, but given the ubiquitous myth of 1911s being unreliable, I should have had at least one hiccup in about 1000 rds through two different pistols.
