Welcome from Big Sky Country.
I bought my PM9 a year ago mid summer. It has probably 500 rounds through it and it has not missed a beat. Maybe the early model one's had issues but not the later ones. It was my first subcompact and I thought the recoil was a little heavy until I purchased a Ruger LCP.
I love shooting the PM9 compared to the LCP and the PM9 is an accurate little subcompact.
Good luck and don't look back.
