Dossier: Ruger Mark IV

Published · Researched 2026-09-21

Overview

• Maker: Sturm, Ruger & Co., Prescott, AZ, USA.
• Purpose: .22 LR semi-auto target/plinking pistol — the rimfire trainer, bullseye, and suppressor-host standard. Introduced 2016; the landmark change was the one-button takedown that ended the infamous reassembly struggle of the Mk I/II/III.
• Current 2026 versions: Mark IV Target (5.5" bull barrel), Hunter, Competition, 22/45 (polymer 1911-grip-angle frame), 22/45 Lite (lightweight, 4.4" threaded barrel, optics rail), 22/45 Tactical, 75th Anniversary, 250th Anniversary Edition, distributor Cerakote editions (e.g., Magpul FDE 22/45), Silencer Shop editions.

Social standing

• Platform pulse: Revered as the default .22 pistol recommendation — "hard to go wrong" — with the one-button takedown universally praised against the old models ("Cause if you have trouble breaking down a MK IV, you're beyond help. It's just pushing a single button"). The two durable criticisms: the factory trigger (gritty, long overtravel) and the 2017 recall that still confuses buyers. Threads (May 2026): @reap.er61 — "i kinda want to use and have the ruger mark IV gun because its the quietest pistol and cheap bullets"; @rodrigo4746hh on shooting one — "It's super fun."
• Group consensus (owner forums):
  • thearmorylife forum: owner of two Mark IVs, both recalled — "Ruger customer service was great. Turn around about 1 week and they gave me 2 free mags (one for each gun), for the trouble."
  • longrangehunting: recall service — "Had mine serviced. No big deal and they send it back with an extra mag." Another: two Mk IVs bought Nov 2017 already retrofitted per serial lookup; tip to look for the "S" marked in the white safety position as proof of retrofit.
  • texags ("Ruger Mark IV Owners Do You Recommend This Target Pistol?"): one owner had ~60% FTE/FTF early — "I sent it back to Ruger. They replaced the bolt and extractor. Now with CCI 40gr round nose it is flawless." Debate over reassembly difficulty is really about the old models: "wrong. mk I, II, III are impossible to reassemble. The beauty of the mk IV is the absolute ease to take down and reassemble."
  • smith-wessonforum ("Ruger MK IV - Terrible trigger"): recall turnaround "four days, including the day I sent it in" plus a free extra magazine; factory trigger overtravel fixed with a trigger shoe; consensus that the Volquartsen accurizing kit is the reliable trigger fix ("the full $100+ Volquartsen accurizing kit" being the one agreed solution).
  • Slav Guns 22/45 Lite review (2026-09-21, affiliate-marked): "Hard to go wrong with a Mark IV if you want an all-around .22 LR pistol — they fixed the old takedown complaint." Honest gripes: the front-pivoting safety is easy to nudge up accidentally with a thumbs-forward grip, and the bolt release can pinch a thumb/finger. "MSRP starting around $410, street around $350" (base models, as filmed). Strong suppressor-host notes: CCI subsonic clearly quieter; thread protector praised.
• Recall — dated, confirmed facts: On June 8, 2017, Ruger recalled Mark IV pistols manufactured before June 1, 2017. The defect: with the safety midway between "safe" and "fire," the pistol might not fire when the trigger was pulled but could discharge when the trigger was released. Ruger replaced the safety mechanism free and returned guns with an extra magazine. Retrofitted pistols are marked with an "S" in the white safety position. Correction to a common confusion: the recall was about the safety discharge issue, not the one-button takedown mechanism itself — the takedown button worked as designed; it was the new safety geometry that was defective. No injuries were reported. Sources: NH Business Review (6/8/2017), Ruger's recall page (ruger.com/dataProcess/markIVRecall, referenced by owners), ar15.com recall thread (June 2017).
• Recurring praise: One-button takedown/reassembly; accuracy (bull barrel Target models); cheap .22 LR training; excellent suppressor host (threaded Lite/Tactical models, optics rails); Ruger's recall and warranty service.
• Recurring complaints / failure modes: (1) Factory trigger — gritty, staged letoff, excessive overtravel; Volquartsen kit is the accepted cure. (2) Ammo pickiness in some guns — one owner needed bolt+extractor replacement; standard-velocity ammo may not cycle in some samples (CCI Mini-Mag / 40gr round nose is the community default). (3) Magazine disconnect on some models (removed by the Volquartsen kit). (4) Small safety lever easy to accidentally engage with a high thumbs-forward grip (22/45 Lite). (5) Bolt-release pinch for new/young shooters.

Social validation

• Tier 1: Ruger safety recall notice (June 2017) — proves scope (all Mark IVs made before 6/1/2017), defect (mid-safety discharge), remedy (free safety replacement + extra magazine), and the "S" retrofit mark.
• Tier 2: NH Business Review (6/8/2017) — independent press confirmation of the recall and its terms; Slav Guns 22/45 Lite review (2026-09-21, affiliate-marked) — proves current-model handling, suppressor-host quality, and street pricing.
• Tier 3: longrangehunting, texags, thearmorylife, smith-wessonforum, ar15.com owner threads — prove recall-service experience, early reliability fixes, trigger complaints, and the takedown consensus; Threads posts (May 2026) — prove current "fun first .22" appeal.

What's included / else needed

• In the box: Two 10-round magazines, hard plastic case, lock, scope-base adapter (Target/Hunter), Picatinny rail sections and thread protector on Lite/Tactical models.
• Else needed (owner consensus): Lots of .22 LR — CCI 40gr round nose / Mini-Mag is the community default for break-in and reliability; a red dot for the railed models; Volquartsen accurizing kit if the factory trigger bothers you; suppressor + subsonic ammo (CCI subsonic praised) for the threaded models; note suppressor ownership is NFA-regulated — federal paperwork and state law apply (UNVERIFIED details; check current law).

Support reality

• Warranty: UNVERIFIED — Ruger's formal written warranty terms were not located in this pass.
• Parts/service: Factory parts, magazines, and the deep Volquartsen/Tandemkross aftermarket are all readily available.
• Community-reported support reputation: Excellent and recall-proven. Multiple owners report 4-day to 1-week turnaround with a free extra magazine on the 2017 recall; bolt and extractor replaced free on a malfunctioning gun; one owner notes a replaced rusted LCP slide and corrected magazine from the same CS operation. An FFL on ar15.com's warranty thread: Ruger replaced a destroyed gun "quickly and at a discount."

Community verdict

The Mark IV is the default answer for a .22 pistol because the one-button takedown genuinely solved the platform's historic complaint, and Ruger backed the 2017 safety recall with fast, free, no-drama service that owners still cite as the reason they trust the brand. Buy it for cheap training, bullseye, or a suppressor host; budget the Volquartsen trigger kit if you're picky about triggers, and check any used gun for the "S" retrofit mark — pre-June-2017 guns without it still need the free safety fix.
