I respect Chuck's opinions on the LEM and P30 and a manual safety. For me, I absolutely hate the LEM trigger or any hammer fired DAO. Being a long time SIG Sauer shooter I am at home with DA/SA and run it very well. The P30 is an extremely desirable pistol and my hands down favorite of the many pistols I own. There is a price difference but HKs are worth every penny spent on them.

The M&P is a wonderful pistol and after working with them I will never buy another Glock. Concerning an external safety, that is an option for you to decide upon. The safety has its place in certain applications and atmospheres and I prefer them on light trigger pull striker fired pistols. The safety can be used when you want to or just left off. If you don't have the safety, you can't use it. Best of luck with your decision. Bill
