Re: Need help 9mm compact..
What is your price range or do you have one?
I own the Kimber Solo. The chore for you right now is finding one at a decent price. The Kimber has the best trigger of any micro-compact pistol that I have shot or dry fired at the store. It is very close to the SA action of my PPK. The Solo trigger is "better" than pretty much any DA only trigger. Due to the "extra" mass of the Solo, I have no problems shooting it at the range. The LCP that I owned was not as pleasant.
I really like the thumb safety on the Solo, given the trigger. I also like the sights, you can actually use them and aim.
Most important, you need to handle them all, you may or may not like the way one or any of them feel in your hand. I did not care for the Sig 290 at all, very brick like.
Good luck.
