Ok guys try and take it easy on me this is my first post but I have some questions about new p2k. This is my first pistol and I am very happy with my purchase. I have put about 400 rds. through it so I am still getting used to it. Anyways I have been reading about the LEM and DA/SA trigger on this forum trying to figure which one I have. How do I know what it is? Which is better? I think it's DA/SA according to what the sales person at the shop explained. What exactly does the LEM do? What is the best ammo to use for practice range? I have been using Winchsters FMJ 115grd. It's the cheapest I can find but if it's going to affect the performance of the gun I will spend a few extra bucks and get the better ammo. A friend said I can only use FMJ is that true? Any help with any of this would be greatly appreciated. I know I will have more questions.
