I'm the one that brought up triggers. Everything everyone was mentioning was double action trigger, but I firmly believe there are some benefits to a single action trigger for those that wish to investigate and train to make them part of their shooting nature.
1911 platform remained king of the hill for a lot of years for a lot of reasons. Being SAO was one of the reasons. It is also one of the reasons the 1911 platform is so widely used by competition shooters. The 21st century has brought us a lot of tiny guns based on the 1911 style platform, some are even great for pocket carry. A double action trigger was a breakthrough for a revolver, not so much for a semi-auto pistol. I like a mechanical safety rather than a long draw trigger. Some DAs have them, but you still have that long drawn out trigger pull to master. I like pull, click, BANG versus pull, pull, pull, pull, click, BANG (click being that breaking point in the trigger just before it releases the round).
If you train with a mechanical safety and have proper carry gear, that safety is covered by the carry gear so it cannot be clicked-off accidently. This is especially key if the safety is ambidextrous. The carry gear should have the control on the outside of your body covered, or you should have the outer control removed. When you train, the safety should be clicked off as the safety clears the holster. This should remain the same for any trigger style.
If you train properly, your finger doesn't touch the trigger until you are aimed at your target. Previous comments about accidental discharges happen due to improper gun handling skills, not the trigger type. Someone in a full-panic fight or flight situation is going to squeeze the trigger to the max if they have their finger on it.
All in all, I want the least time between my finger touching the trigger and the gun going bang as possible. I don't want my aim to drift, or have the bad-guy get a shot off at me, or any of the millions of things that could go bad in such situations, just because my trigger has extra travel distance to go before going bang. I don't want to have to pay for the damages of a misplaced shot. I don't want to pay for the damages of a perfect shot where the shot window changed during the course of my committing to pulling the trigger and the bullet travelling downrange. I don't want the bad guy ducking for cover and me only catching a thin layer of meat and shooting through and hitting something or someone that was behind him. I want center mass, first time and any time after that until the threat is resolved.
