I understand the concern.
However, my Keltec PMR 22 magnum has been 100% reliable with its 30 round magazines when used with recommended ammo.
Even with some “off brand” ammo not on their recommended list.
Of course, it’s never used in combat conditions.
You are VERY lucky.
(Or have a good gunsmith.)
I understand that recent versions have much improved reliability with specific ammo, but the earlier versions are ‘Jam-0-Matics, and reliability is still a bit of a crap-shoot even with the newer ones.
I REALLY wanted one when they first came out, but they were selling for double or more of what MSRP was if you could even find one, and the reliability problems started making the news... By the time the prices came down, I lost interest.
