The very first semi auto I ever bought (other than a Baby Browning back in the '60's) was a Ruger P97dc, which I still have and which has never had even the most minor failure. I have not had a single reason to dislike any of my Rugers, and I now several a bunch, other than the PITA of re-assembling my EDC (an LC9s) because of the seating of the spring which has to be just right or you can't engage the barrel. My Mark IV is one I especiall enjoy since it is very accurate, totally reliable with decent ammunition, and could not be simpler to take apart and clean. I used to think that my Glocks were the easiest to dissassemble but the Mark IV takes the honor now.
