My Witness 10MM (Wonder Finish) was my first carry gun. I still carry it upon occasion. The only thing that slows me down from full time carry is that the ammo is significantly more expensive than 40 S&W or 45ACP and a little tougher to find. I like to practice with the ammo I carry. The size and weight don't bother me much, but I'm 6'4" and 240-250.
