Notes
The 22/45 Tactical ships with a thread protector and an included washer for safety conversion (to left-side only operation). The receiver is drilled and tapped for Weaver- or Picatinny-style rail mounting in addition to the factory-installed under-barrel accessory rail. The threaded barrel uses a 1/2"-28 thread pattern, the most common thread pitch for .22 LR suppressors. The trigger is single-action only with a factory pull weight of approximately 5 pounds (22.2 N). The 1:16-inch right-hand twist with 6 grooves stabilizes standard- and high-velocity .22 LR loads. Two 10-round magazines are included. The checkered 1911-style polymer grip panels are replaceable with aftermarket grips. MSRP is $689. Not available in California or Massachusetts.
Background
The 22/45 Tactical occupies the practical middle ground in the Mark IV lineup, offering the suppressor-ready threaded barrel and accessory rail that the standard 22/45 lacks while remaining lighter and more affordable than the Competition or Hunter models. It has become a staple of tactical rimfire training programs where shooters practice drills with inexpensive .22 LR ammunition before transitioning to centerfire pistols.
