I have a PC9, and the trigger on that is really pretty good. It is a little heavy, but lighter than most rifle-caliber carbines, and it is incredibly rugged and reliable. You can get decent MecGar mags for it.
The only real downside is that disassembly for cleaning is a royal pain.
I was thinking about selling mine because I hardly ever shoot it, but the way things have been going lately, I changed my mind. This would be a great gun for a smaller person to have in an emergency situation. Instead of selling it, I bought some new high-cap MecGar mags.
