The Standard Manufacturing Switch Gun is a compact folding revolver chambered for both .22 WMR and .22 LR, with a 0.75-inch barrel and a 5-round cylinder. The stainless construction and folding design make it an unusually small package. This is a short-barreled configuration; transfer requires additional federal paperwork.

Owners of the Standard Manufacturing Switch Gun tend to treat it as a novelty-plus-utility piece, appreciating its genuinely small folded size in a way that photos do not fully convey. The dual-caliber capability is a practical feature that owners mention favorably.

The short barrel limits practical accuracy beyond close range, which most owners acknowledge up front. The trigger on a small-frame revolver like this gets mixed marks; some find it workable, others note it is stiff and requires practice. The Switch Gun name and mechanism attract curiosity at the range.

The federal paperwork requirement is the primary friction point in ownership discussions, and first-time buyers sometimes underestimate the process. Those who have navigated it report satisfaction with the finished piece, though the price-to-round-count ratio is a common point of debate.

Having both the 22 LR and 22 Magnum cylinders is what makes this version particularly appealing to me. The ability to switch between them gives the little revolver a useful kind of versatility, and the folding design is genuinely clever. I have also found it suitable as a backup. It can be opened while still inside my pocket without being restricted, which supports a quick draw if that were ever necessary. I considered other small 22 options before settling on the Switch Gun, and I am very satisfied with this choice. The compact folding concept is unusual, but it is the combination of that design and the two included cylinders that really won me over.
