What is a high capacity for a pistol, more than 6? more than 10? just about any magazine fed pistol you can slap in an extended magazine in place of the regular one.
Up here, any handgun magazine that holds more than 10 rounds gets classified as "prohibited" (not prohibited prohibited. It's technically possible for someone to be licensed to possess "prohibited" weapons, but it's almost impossible to actually do so). Handguns in general are "restricted" and far more rare than in the USA, and you can pretty much forget about carrying one around unless you're an armoured car guard or similar or can convince a judge you have a real good reason to carry one.
For semi-automatic centre-fire rifles (manual action rifles or anything using rim-fire ammunition can have as much magazine as you like), the limit is 5 rounds.
