I own both a long and short slide model with a good pile of mags bumped to 17 rounds (2 kits are required to do this)..
They are a .22lr so are never going to be never-fail like a quality cared-for 9mm but they are great, no more jamomatic than say a 10-22..
The ammo I've settled on are 40 grain round nose cci mini mags, not for the 40 grain rather hollow points are pointless (well literally

).. though I'm not sure I can say it runs any different on the 36 grain that comes only in hollow point. That's all I stock for all .22lr guns and they all like it.
