The articles that I have read suggest that the trigger is not so great. I have had several PF-9's. Each time I sell one, I end up with another. Real hard to beat for the money.
I got that bug that makes me want to play with new stuff all the time. I get rid of something to get something else. I hope to get over it soon, I have a trail of regrets a mile long. My daily carry is a KelTec .380.
