North American Arms produces a unique and well-made series of miniaturized, fully functional stainless-steel rimfire revolvers. There is, however, an impressive RS offering which not only looks the part, but is easily available and – crucially – highly affordable: the True North Arms Ambi Mag Catch. It’s very close to the Colt Canada item I am seeking to simulate, as can be seen in this comparison pic that I’ve mocked up for the reader’s viewing pleasure.
