170,000 rounds without any issues. That’s how hardcore the original MR73s were tested, and with red-hot European .357 Magnum ammo at that. Until 2021, new manufactured MR73s were extremely rare, and their owners tended to treat them like museum pieces, instead of fighting handguns. When we set out to review the MR73, the goal wasn’t to tell you how accurate it is, or how beautifully it’s put together, but rather to run it hard and see what happens. Shoot fast, reload fast, slam metal into metal chasing sub 0.20 splits.
