Well, let's be realistic... tinker tinker tweak and finagle, or it works out of the box?
TS has more experience than I ever will on both sides of the 1911/HK debate, but *I* have not had a single issue with any of the HK's I currently own, or have owned. For me, it just falls back to always owning a tool that does the job to the point that any errors are mine and mine alone... Limiting the variables in the equation, and all that.
Easier to honestly know I and I alone failed a task, than to have to question my equipment's capabilities.
