I have the new LCP custom. I had 2 of the others versions before this one. The trigger system is what made me change. The pull is better and the shape of the trigger eliminated the pinched finger between the trigger and guard. The sights are better, if you use them.
For me, this is a "weak hand" pocket pistol for serious, upclose work. For that I don't need sights, but I do want a very good trigger.
