I recently shot 100 rounds of this through a brand new Sig P290RS. Out of 100 rounds, I had one misfire. I tried the restrike capability of the pistol, and the round again did not fire. Hit it twice and still looked like a light primer strike, compared to the fired brass from the pistol. Also had one fail to feed on the last round of an extended magazine.

Since this was the first one hundred rounds through the pistol, not sure if it was the gun or the ammo.
