Galco Ankle Glove Holster Springfield XD Sub-Compact 3" Leather with Neoprene Leg Band Black
Ankle Gloves for small revolvers are an open top design, meaning they do not have a safety strap and thumbreak. Instead, they have a tension unit, and work with both hammered and hammerless guns.
Other models have a retention strap (thumb break) that runs behind the grip frame (not behind the hammer). They work with both hammered and hammerless guns, but some guns with factory supplied custom or oversized rubber grips will not fit because the retention strap is not long enough to wrap around them.
