Found some decently priced 9mm , but it's older then me, and that's old lol. Would y'all trust it?

Description: The 9mm Mk. IZ cartridge was introduced during World War II for use in Sten submachine guns, but it was discovered this round was insufficiently powerful to work the action of this gun reliably. Sometimes the bolt did not recoil far enough for the bent and sear to re-engage. On occasion, a Sten would "run away" and fire full-automatically until the magazine was empty. To solve this, the muzzle velocity was raised from 1250 f.p.s. to 1300 f.p.s., and the higher velocity round was given the the designation 9mm Mk. 2Z. This change was approved on March 15, 1944 and at the same time the 9mm Mk. IZ cartridge was made obsolescent. Remaining stocks of 9mm Mk. IZ ammunition were marked "Pistol Use Only." The 9mm Mk. IZ cartridge was made officially obsolete on June 6, 1957
