I got hit really hard with the desire to get decent in pistolcraft a year ago. I had been a bit of several things, mostly XD (don't make fun of me, I do still own a couple, too), but when I started shooting DA/SA, I quickly decided that was the system I wanted to get good at.
So now I'm a Beretta junkie, and I'll be mostly/largely on the 92 series. There's that weirdness of railed vs non railed, and that could prove annoying if I get a railed copy, but we'll cross that bridge later. I tend to gravitate toward M9/92FS or M9A1 frames. It makes life pretty simple, with holster and mag compatibility. I have a heap of mags for them, and can run the full size mags in the compact, if desired.
I did add a PX4 compact to the mix, and it would be more a of a range toy if it wasn't for the fact that the short barrel makes it really handy on the draw, and the hammer doesn't seem to bite that last bit of tactical shelf I still have.
I've still got the other pistols, and don't see cause to shell them all off, but my shooting is focused on the M9/92 80% or more.
