Built around a micro-size format, this Casull's Improvement keeps things minimal and compact while still providing .22 WMR chambering and a 4-round cylinder. The cylinder is fluted and configured as a four-chamber, 4-shot design.
Functionally, it is a single-action-only revolver with an exposed hammer. It uses a spur-style trigger with no trigger guard and is fitted with black synthetic-style grip panels in a birdshead-style grip profile.
Sights are fixed, with a small fixed front blade and a rear groove/notch that is integral to the topstrap. The revolver is finished in a silver-colored tone on the frame, cylinder, and overall exterior.
Additional visible details include a removable cylinder pin/latch assembly with a knurled control located under/at the front of the barrel. The serial number is marked with a "B" prefix.
