The Glock trigger takes some getting used to if you are accustomed to more traditional trigger action. But I came to appreciate it, particularly its consistent feel on every shot. It's like DAO but without the long and heavy pull. I also like DA/SA style, and I am with Libertas on the subject of safeties. I am a firm believer in the concept that the only "safety" is the one between your ears. To me a safe design means a gun that absolutely will not discharge unless the trigger is fully pulled in a deliberate manner, and if those conditions are met it will not not discharge.
Some people prefer manual safety levers, and that's understandable. Personally I can do without.
