I thought for awhile about trading my PF9. Really don't think I will get rid of it though. It's cheap and wouldn't fetch as much money as it is worth to me.
The main reason I considered getting rid of it is that it lacks double strike capability. In reality, it shouldn't be as much a deal breaker, but until I find something as small and powerful (and reliable), it's going to stay with me.
That is never a consideration for me. I never see a situation where I am not going to rack a new round in place, rather than give the old round another shot. If a gun has light primer strikes, I fix it or get rid of it. I don't see that double strike capability really adds anything.
