About this product
What is the Standard Manufacturing Switch-Gun .22 WMR? It is a single-action folding revolver with a 0.75″ stainless steel barrel, designed for deep concealment where traditional pocket pistols might print. This 5-round .22 WMR platform reduces its folded footprint to just 2.125" x 3.75" x .75" through a unique hinge mechanism that completely encapsulates the trigger guard within the polymer grip when stowed. Based on my experience with Title II item applications and compact defense tools, this represents a niche but mechanically sound solution for a specific carry problem.
What is the Standard Manufacturing Switch-Gun used for?
This tool is designed for deep-concealment backup or administrative carry where absolute minimal print is non-negotiable. Its primary function is to provide a last-resort defensive option that can be carried in a front pocket, ankle holster, or specialized pouch with virtually zero detectable signature. The 0.75" barrel and .22 WMR cartridge generate approximately 215 ft-lbs of muzzle energy, making it suitable for close-range defensive use, but not for recreational shooting or primary duty carry. The folding design prioritizes safety during storage and rapid, one-handed deployment over high-capacity or rapid follow-up shots.
How does the Standard Manufacturing Switch-Gun compare to the North American Arms Mini-Revolver?
The Switch-Gun offers superior trigger safety and a more controlled grip when deployed compared to the North American Arms .22 Magnum Mini-Revolver. While the NAA mini-revolver weighs approximately 6.5 ounces and has a similar barrel length, its exposed trigger and tiny grip make it more difficult to fire accurately and risk snagging in a pocket. The Switch-Gun's polymer grip, which expands to a full 4.2-inch length when opened, provides better control and its closed design eliminates inadvertent trigger contact entirely. The NAA is better for pure minimalist weight, but the Switch-Gun is better for incorporating a meaningful safety protocol into its carry mechanism.
What does it weigh and what are the dimensions?
The Switch-Gun weighs 18.4 ounces (521 grams) with an empty cylinder, a significant heft for its size due to the CNC-machined 416 stainless steel frame and barrel. Its folded dimensions are 2.125" in height, 3.75" in length, and .75" in width—nearly identical to a large box of matches. When unfolded for firing, the overall length extends to 6.9 inches, with the grip accounting for the majority of that length, providing a usable purchase for a two-finger hold. The cylinder has a diameter of 1.3 inches, which dictates the folded profile.
Who is this NOT for?
This is not for a new shooter seeking a primary training firearm or for someone prioritizing high-volume recreational shooting. The single-action mechanism requires manually cocking the hammer for each of the 5 shots, which is slow compared to any semi-automatic pistol like the Stevens 334 Rifle. It’s also not ideal for ballistic performance seekers; the 0.75" barrel creates significant unburned powder and flash, reducing the .22 WMR's potential velocity by roughly 40% compared to a 4-inch barrel. If your need is for a general-purpose plinker or a primary defensive tool with capacity, look elsewhere.
What's in the box?
You receive the Switch-Gun revolver, one 5-round cylinder, and a molded plastic storage case. Standard Manufacturing does not include a cable lock, cleaning rod, or additional speed loaders with this model, as it is considered a specialist tool. The case has a specific cutout for the folded firearm and a separate compartment that can hold approximately 25 rounds of loose ammunition. There is no manual safety key or trigger lock provided, as the folded grip itself acts as the primary safety device.
Is the Standard Manufacturing Switch-Gun worth it at $385.99?
At $385.99, it is worth the cost only if your specific operational requirement is a completely snag-free, ultra-compact revolver with an integrated mechanical safety for deep carry. You are paying a premium for the CNC machining of a complex stainless steel hinge and frame, a process more expensive than casting. For a hunter or sport shooter looking for a more versatile Stevens 555 Sporting O/U 12 Gauge, this money is better spent elsewhere. But for its singular design purpose—safe, discreet, always-accessible backup—the price reflects its specialized manufacturing and fills a narrow market gap.

Pros & cons
What works
- Folds to 2.125" x 3.75" x .75" — smaller than most smartphones for complete concealment.
- CNC-machined 416 stainless steel frame — provides a rigid, durable hinge mechanism rated for thousands of cycles.
- 18.4 oz unloaded weight — offers a stable feel in hand despite compact size, reducing perceived recoil.
- Trigger fully encapsulated when folded — eliminates need for external safety or trigger guard cover.
Trade-offs
- Single-action only — requires manually cocking hammer for each of the 5 shots, slowing follow-ups.
- 0.75" barrel — sacrifices significant ballistic performance, with velocity loss around 40% vs. a 4" barrel.
- No accessory rail or mounting points — cannot attach lights or lasers for low-light identification.
- Proprietary design — aftermarket grips, holsters, and speedloaders are extremely limited.

Frequently asked questions
- Is it compatible with .22 LR ammunition?
- No, it is not compatible. The Switch-Gun is chambered exclusively for .22 Winchester Magnum Rimfire (.22 WMR). Firing .22 Long Rifle cartridges in this chamber can cause dangerous pressure issues and extraction failures due to the shorter case length. Always use ammunition specified on the barrel and in the manual, typically 40-grain JHP .22 WMR.
- Does it fit in a standard pocket holster?
- It fits in most dedicated 'pocket pistol' holsters designed for items under 4 inches in length and 1 inch in width. For optimal orientation and quick access, a holster with a molded shape for a 3.75" x 2.125" footprint is recommended. We suggest DeSantis or Sticky Holsters for custom fitted options.
- How long does shipping take to an FFL?
- Processing and shipping typically take 3-5 business days once payment and FFL information are verified. Transit time varies by carrier and location, but ground shipping usually adds 2-7 additional business days. You must coordinate directly with your chosen FFL dealer for pickup upon arrival.
- Can I return it if it doesn't fit my hand?
- No, firearms sales are final once the transfer is completed at your Federal Firearms License (FFL) dealer. Due to federal regulations, we cannot accept returns of transferred firearms. It is crucial to review the grip dimensions (4.2" length when open) and, if possible, handle one at a local dealer before purchasing online.
- Does this work with a suppressor?
- Technically no, and legally it's complicated. The 0.75" barrel is not threaded for a suppressor. Even if threaded, attaching a suppressor to a barrel under 16 inches in length would create a regulated Short-Barreled Rifle (SBR) under the National Firearms Act (NFA), requiring a tax stamp and registration. This design is not intended for suppressed use.
