My wife carries the XD 40 Subcompact. Springfield is tried and true with a great line of pistols. The 1911 type of firearm is a reliable design, having been rode hard and tested through many wars and competitions. The EMP is a 1911 design, but shrunk for 9mm and .40S&W. Being that it's got a 3" barrel only means she's not going to shoot a 2" group at 50 yards. The 9mm is a great round with about as much destructive force as a .45, but in a more compact form. I read a couple reviews of the EMP and they were both positive
I would not hesitate to trust my life to the EMP. The majority of personal defense situations that involve a firearm are in less than 10 feet. Not to mention that it's one sleek sexy pistol. If you want to be sure of it, take it to the range and put it through it's paces. Shoot at 15' or less, rapid fire, quick reloading, use both ball and HP ammo. After putting 100 rounds through it, if it doesn't have a FTF or FTE you can trust it. Then give it a good cleaning and lube. Remember to treat them with TLC, but also remember that they are a tool and as with all tools, you get better with practice.
