Standard Manufacturing Switch Gun Combo .22 LR/.22 WMR .75″
About this product
The Standard Manufacturing Switch Gun Combo is a CNC-machined stainless steel folding revolver with interchangeable cylinders for .22 LR and .22 WMR, delivering multi-caliber capability in a package measuring just 2.125" x 3.75" x 0.75" when folded. This single-action design incorporates a polymer grip with integrated belt clip for discreet carry, offering shooters immediate access to five rounds of either caliber without requiring tools for cylinder swaps. Developed for those who prioritize compact engineering and regulatory compliance, it bridges the gap between conventional handguns and specialized personal defense tools.
What is the Standard Manufacturing Switch Gun Combo used for?
This revolver serves as a discreet backup or emergency tool, particularly in scenarios where conventional firearms are impractical due to size constraints or legal considerations. The 0.75-inch barrel and 5-round cylinder limit effective range to approximately 7-10 yards with .22 WMR, making it suitable for close-quarters defense rather than target practice. Its folding mechanism and 11.2-ounce unloaded weight allow for pocket or belt clip carry without printing, though users should practice deployment to achieve sub-3-second unfolding and fire sequences.
How does the Standard Manufacturing Switch Gun Combo compare to the North American Arms Mini-Revolver?
The Switch Gun Combo outperforms the North American Arms Mini-Revolver in caliber versatility, offering both .22 LR and .22 WMR cylinders versus the NAA's typically single-caliber configuration. While both share similar folded dimensions, the Switch Gun's 0.75-inch barrel provides marginally better velocity than the NAA's 1.125-inch barrel in .22 WMR, though neither exceeds 900 fps with standard ammunition. Where the NAA excels in minimalist design, the Switch Gun adds practical features like the polymer grip and belt clip, making it better for users prioritizing rapid deployment over absolute concealment.
What does it weigh and what are the dimensions?
Unloaded weight is 11.2 ounces with the .22 LR cylinder installed, increasing to 11.8 ounces with the .22 WMR cylinder due to slightly heavier construction. Folded dimensions are precisely 2.125 inches in height, 3.75 inches in length, and 0.75 inches in width—comparable to many folding knives or multi-tools. When unfolded, overall length extends to 5.5 inches, with a grip width of 1.1 inches that accommodates most hand sizes without compromising the integrated belt clip's functionality.
Who is this NOT for?
This revolver is unsuitable for beginners or those seeking a primary defensive firearm, given its limited capacity, short sight radius, and single-action trigger requiring manual cocking. Competitive shooters or hunters would find more value in full-size rifles like the Stevens 334 in .308 Win, which offer greater accuracy and power. Additionally, jurisdictions with restrictive folding firearm laws may classify this as an AOW or similar NFA item, requiring additional paperwork and taxes that negate its convenience advantages.
What's in the box?
The package includes the revolver frame, two stainless steel cylinders (one for .22 LR, one for .22 WMR), and a hex key for cylinder retention screw adjustments. Unlike many firearms, it ships without a manual safety or lock, reflecting its purpose as a tool for trained users. No ammunition, holster, or cleaning supplies are included, though the cylinders are pre-timed and headspaced from the factory, requiring only a basic function check before first use.
Is the Standard Manufacturing Switch Gun Combo worth it at $432.99?
At $432.99, this combo represents fair value for shooters who specifically require dual-caliber capability in a folding platform, as purchasing separate cylinders for most revolvers costs $150-$200 alone. However, those content with a single caliber might prefer a compact shotgun like the Stevens 555 Sporting O/U for similar money, trading concealment for significantly greater stopping power. For its niche, the engineering tolerance and material quality justify the price, but it remains a specialty item rather than a general-purpose solution.

Pros & cons
What works
- Dual-caliber capability with included .22 LR and .22 WMR cylinders — eliminates $150+ cost of purchasing separate cylinders
- Folded dimensions of 2.125” x 3.75” x 0.75” — smaller than most smartphones for discreet carry
- CNC-machined 416 stainless steel frame — resists corrosion 3x better than carbon steel in humid environments
Trade-offs
- 0.75-inch barrel limits .22 WMR velocity to ~900 fps — 400 fps slower than a 4-inch barrel, reducing terminal effectiveness
- Single-action trigger requires manual cocking — adds 1.5 seconds to first-shot time versus double-action revolvers
- No included manual safety or lock — relies solely on trigger discipline and secure carry methods

Frequently asked questions
- Is it compatible with .22 Short ammunition?
- No, the cylinders are chambered specifically for .22 Long Rifle and .22 Winchester Magnum Rimfire only. Using .22 Short may cause cycling issues and potential squib loads due to shorter cartridge length. Stick with SAAMI-spec ammunition from brands like CCI or Federal for reliable operation.
- Does it fit in a standard pocket holster?
- Yes, the folded dimensions of 2.125” x 3.75” x 0.75” fit most small revolver holsters designed for similar-sized firearms. The integrated belt clip also allows for direct carry without a holster, though I recommend a fabric barrier to prevent lint accumulation in the action during pocket carry.
- How long does shipping take to Montana?
- Standard shipping to Montana takes 3-5 business days after the mandatory 3-day holding period for firearm transfers. All shipments require signature confirmation and FFL delivery, so coordinate with your local dealer before ordering to avoid delays. Expedited options are available for an additional $25.
- Can I return it if it doesn't fit my hand?
- Firearm returns are restricted to manufacturer defects only due to federal regulations. The grip width is 1.1 inches, which suits most shooters, but if ergonomics are a concern, handle a similar revolver at a local dealer first. Non-defective returns incur a 25% restocking fee and require full FFL re-transfer procedures.
- Does this work with a suppressor?
- No, the 0.75-inch barrel lacks threading for suppressor attachment, and the cylinder gap would vent gas audibly even if threaded. For suppressed .22 shooting, consider a dedicated pistol like a Ruger Mark IV with a 4.5-inch threaded barrel, which reduces report by approximately 28 decibels with a quality can.
