The large frame Witness pistols, yes. The small frame Witness pistols, including the TZ-75 Series 88, calibers were only 9x19mm, 40 S&W, and 41 Action Express. These days, other than used parts, it's pretty difficult to find compatible parts for the small frame pistols. I was lusting for a large frame Witness pistol, either in 10mm Auto or 45 ACP, with a finish that would mimic stainless steel, but then I lucked into not one, but two S&W 645's, then a mid-1980's era Galco shoulder rig to satisfy my inner Sonny Crockett.The good thing about a Witness is the ease of switching calibers, takes less than a minute.

The badge is for display purposes only, not for carry, so no need to ask if I use the badge.
