I've only handled the LC9 at a gun shop.
I bought the PF9 a few years ago because of it's caliber and small size. It gets carried more than my other 7 pistols combined. There are some small 9s that I like to shoot better, but the PF9 always wins in size. It also fits my hand very well with the magazine lip on it.
I also handload, and here's my experience with it.
115gr MG FMJ, 4.9gr 231 - Very nice shooting load and doesn't hurt my finger at all. brass goes 2-3 ft.
147gr MBC TC, 4.8gr HS-6 - Even lighter shooting, brass lands near my feet.
Factory S&B - stings my finger a bit with each round. Most snappy of these loads.
115gr MG FMJ, 6.8gr HS-6 - throws brass almost 10ft. Fun to shoot, but stout push type recoil for a 9mm
95gr TMJ, 7.5gr HS-6 - About the same.
I havent' tested any for accuracy because I'm really only concerned with hitting an 8x10 paper at 10yds, because that's what the PF9 is for.
