Once Ruger's great customer support addressed the problems with my original (they sent me a new gun), my confidence grew substantially in the reliability of my SR9. I probably have 1000 rounds through it; training, IDPA, etc. The SR9 is now my daily carry weapon, and it has given me no reason to regret that decision.
For the record, I keep my gun very clean, making sure it's field stripped and cleaned after every shoot. I also removed the mag disconnect "safety" because a) I don't like that "feature"; b) it complicates the "unload and show clear" process during IDPA matches.
I hope you enjoy yours.
