Let's focus on home defense guns with a price tag of <$1500 if possible.
I took my HK P30 and P2000SK to the range yesterday. The P30 was dead accurate. I used to think I was a terrible shooter

.
However, what impressed me the most was the P2000SK. That tiny thing enabled me to shoot as accurately as my P30. I did use a 15-round magazine, so that half-inch extension to the grip perhaps helped. I suspect the main reason it was so accurate was due to the weight of the slide. That handgun surely feel top heavy.
