About this product
The Ruger Mark IV 22/45 Tactical 22 LR 4.4″ Threaded 10rd is a rimfire pistol purpose-built for shooters who want accurate, low-recoil practice on a platform that mirrors a full-size tactical pistol. With a 4.40-inch threaded barrel (1/2″-28 pattern), dual Picatinny rails, and a crisp trigger, this gun is ready for suppressor use, red-dot optics, and high-volume range days right out of the box.

Key Features
- Threaded barrel with 1/2″-28 pattern — why it matters: lets you run a suppressor or compensator without a gunsmith, keeping your setup quiet and flat-shooting at the range or in the field.
- Top and bottom Picatinny rails — why it matters: mount a red dot, mini reflex, or weapon light instantly, turning this rimfire into a trainer or a night-vision-ready host without adapters.
- One-button takedown — why it matters: field-strip the pistol in seconds for cleaning or swapping parts, no tools needed, so you spend less time messing with springs and more time shooting.
- Two 10-round magazines included — why it matters: double the fun between reloads, and spare mags mean you can run drills or plink without constant downtime.
- Adjustable rear sight — why it matters: fine-tune your point of impact for different ammo types or distances, giving you consistent accuracy whether you’re zeroing a suppressor or just punching paper.
Who It’s For
This pistol is for EDC enthusiasts who train with rimfire to save money on ammo, suppressor owners looking for a quiet host, and shooters who want a reliable .22 LR trainer that handles like a full-size duty gun. It’s also a solid pick for new shooters who want a low-recoil platform with modern accessory rails.
Pros & Cons
- Pro: Ruger’s Mark IV action is proven reliable with bulk .22 LR ammo, reducing malfunctions during high-volume sessions.
- Pro: The 1911-style grip angle (22/45 design) gives a natural point of aim for shooters used to that platform.
- Con: The factory trigger has some creep and a 4-5 lb pull weight — not as crisp as a dedicated race gun, but fine for most shooters. Aftermarket triggers are available if you want a lighter break.
- Con: The polymer grip panels feel a bit thin for larger hands — aftermarket grip sleeves or VQ grips can fix that.

FAQ
What accessories can I mount on the Ruger Mark IV 22/45 Tactical?
You can mount a red dot or mini reflex sight on the top Picatinny rail, a weapon light or laser on the bottom rail, and a suppressor or compensator on the 1/2″-28 threaded barrel. Most standard Picatinny-compatible accessories work without adapters.
Is this pistol legal in my state?
Check your local laws regarding threaded barrels and magazine capacity. The Ruger Mark IV 22/45 Tactical ships with 10-round magazines, which are compliant in most states. Some states restrict threaded barrels on semi-autos — verify before ordering.
Can I use this for concealed carry?
At 32 oz and 4.4″ barrel, it’s on the heavier side for daily carry, but some shooters do use it for range training or as a truck gun. Most buyers use it as a suppressor host or a trainer, not a primary carry piece.
Does it come with a case?
Yes, Ruger includes a lockable plastic case, two 10-round magazines, a cable lock, and a manual.
How do I clean the barrel after shooting suppressed?
Field-strip using the one-button takedown, then run a bore brush and patches through the barrel. The threaded barrel makes cleaning easy — just remove the muzzle device first.
