I have a Star Ultrastar that shoots very low, even for a European sighted gun. Even so, it groups well and will swallow and fire any ammo. I have a Baby Desert Eagle that has a nasty DA pull, but it is very accurate SA.

My only reliability issues with semis have been with rifles. Once it was an underpowered ammo problem, and the other time it was because I picked up the one bad mag I had for that gun when I took it to the range. Nothing some gentle persuasion with pliers could not cure.
