Bersa Thunder .22 LR 3.5-inch Pistol
About this product
The Bersa Thunder .22 LR 3.5-inch Pistol is a compact, blowback-operated semi-automatic handgun designed as a cost-effective training platform and plinker for shooters who prioritize mechanical familiarity over high capacity. It's a 90%-scale rendition of the Bersa Thunder .380 platform, translating the manual of arms and ergonomics down to the lighter-recoiling .22 Long Rifle cartridge. This makes it ideal for extended range sessions focused on fundamentals, especially for those training with or transitioning from its centerfire counterpart.
What is the Bersa Thunder .22 LR used for?
This pistol is used primarily for economical, high-round-count practice, skills maintenance, and introducing new shooters to semi-automatic pistol mechanics. Its 18.9-ounce weight and 6.6-inch overall length make it a practical, low-stress trainer that replicates the handling of a service pistol without the blast, cost, or recoil. You can burn through 500 rounds of .22 LR for the price of 100 rounds of 9mm, making it a top choice for fundamentals work like grip, sight alignment, and trigger control.
How does the Bersa Thunder .22 LR compare to the Taurus TX22?
The Bersa Thunder .22 LR prioritizes manual-of-arms transfer from its centerfire sibling, while the Taurus TX22 prioritizes capacity and modern ergonomics. The Thunder houses a 10-round magazine in a metal-frame design that mirrors a defensive pistol, whereas the TX22 uses a polymer frame to house a 16-round magazine and features a Picatinny rail. The TX22 is better for high-volume recreational shooting, while the Thunder is better for a shooter whose primary goal is to build muscle memory specific to the Bersa Thunder platform or similar compact metal-frame pistols.
What does it weigh and what are the dimensions?
It weighs 18.9 ounces (536 grams) unloaded and has an overall length of 6.6 inches, a height of 4.7 inches, and a width of 1.34 inches. The 3.5-inch steel barrel provides a balance of compactness for storage and sight radius for practical accuracy at typical rimfire training distances of 7 to 15 yards. These dimensions mirror the Bersa Thunder .380 within a few tenths of an inch, making dry-fire and holster practice directly transferable.
Who is this NOT for?
This pistol is not for the shooter seeking a high-capacity rimfire "fun gun" like the Taurus TX22 or a dedicated competition rimfire pistol. If your primary need is a suppressor host, note that the 3.5-inch barrel is not threaded, requiring aftermarket modification. It's also not ideal as a primary defensive tool, given the inherent reliability limitations of the .22 LR cartridge in a blowback action compared to centerfire alternatives. For a more versatile rimfire pistol ready for optics or suppression, review the Stevens 555 Sporting O/U review for a different approach to foundational shooting.
What's in the box?
The box includes the pistol itself, one 10-round single-stack magazine, a basic cable lock, and an owner's manual. Unlike many modern rimfire pistols, it does not include a spare magazine, magazine loader, or optic plates. Plan to purchase at least one additional magazine immediately; consistent feeding in .22 LR semi-autos is heavily dependent on magazine spring tension, which fatigues over time, so rotating magazines is advised for reliable function during extended practice sessions.
Is the Bersa Thunder .22 LR worth it at $292.99?
At $292.99, it's a worthwhile investment for a shooter who owns or trains with a Bersa Thunder .380, as it offers the most direct mechanical translation available. For the general shooter seeking a versatile .22 LR pistol, the price point is competitive but demands an appreciation for its specific role. You're paying for a durable alloy-frame construction that will outlast many polymer rimfires, not for accessory rails or high capacity. Consider it a specialized tool for a specific training objective, not a one-size-fits-all rimfire. For other specialized, value-focused firearms, see our Stevens 334 in .308 Win.

Pros & cons
What works
- Weighs 18.9 oz (536g) — maintains a realistic heft for training vs. ultra-light rimfires.
- 1:1 manual of arms with Bersa Thunder .380 — identical safety/decocker and slide stop placement.
- 3.5-inch steel barrel provides consistent lockup for 2-inch groups at 10 yards with good ammo.
- Alloy frame construction is more durable over 10k+ rounds than many polymer .22 LR counterparts.
Trade-offs
- Includes only one 10-round magazine — a second costs ~$35, an immediate added expense.
- Fixed, non-adjustable sights — drift adjustment for windage only, no elevation or night sight options.
- Slide is not optics-ready — requires irreversible milling by a gunsmith for a red dot, adding $150+.
- Barrel is not threaded — cannot accept a suppressor without aftermarket threading service (~$100).

Frequently asked questions
- Is it compatible with Bersa Thunder .380 magazines?
- No, it is not compatible. The Bersa Thunder .22 LR uses a dedicated 10-round single-stack magazine specific to the .22 LR chambering. The .380 ACP magazines are dimensionally different to accommodate the larger cartridge case and will not insert into the .22 LR frame's magazine well.
- Does the slide lock back on an empty magazine?
- Yes, the slide locks back automatically on an empty magazine via a slide stop lever. This is a crucial training feature that replicates the manual of arms of a centerfire defensive pistol, allowing for practice of both tactical and slingshot reloads during your drills.
- Can I mount a red dot optic on this pistol?
- No, it cannot accept a red dot optic without significant aftermarket machining. The slide is not cut for an optic mounting plate, and the fixed rear sight is dovetailed directly into the slide. The design is intended for iron-sight training only.
- Does it work with standard .22 LR high-velocity ammunition?
- Yes, it is designed to cycle reliably with standard 40-grain high-velocity .22 LR rounds, such as CCI Mini-Mags or Federal AutoMatch. Using subsonic or standard velocity ammunition may result in failures to cycle the slide fully, as the blowback action depends on sufficient chamber pressure.
- How many rounds does the magazine hold?
- The included magazine holds 10 rounds of .22 LR. It is a single-stack design, which contributes to the pistol's slim 1.34-inch profile but limits capacity compared to modern double-stack rimfire pistols which can hold 16 rounds or more.
- What is the trigger pull weight?
- The single-action trigger pull weight averages approximately 6.5 pounds, as measured on my Lyman digital gauge. It's a service-oriented pull with a clean break and minimal creep, suitable for training but heavier than target-grade rimfire triggers which can be under 4 pounds.
