Many myths have emerged around the OSA system over its many years on the market. In this video, I've compiled the five most frequently circulated "rumors" about this weapon online. Including those actively discussed in the comments.
We tested these myths through extensive testing of two pistols—the OSA M-09 and the OSA PB-4-2. My personal PB-4-2 fired over 100 shots during testing, which is a significant result for a barrel-less weapon. Using simple math, you can calculate that the cost of ammunition has already exceeded the cost of the weapon.
Typically, barrel-less weapons are fired no more than 2-3 packs of 4 rounds during their lifetime. However, the OSA can withstand thousands of rounds of fire without breaking a sweat.
In any case, I'm pleased with the test results; the pistol performed excellently and never malfunctioned during the shooting period.
