I like the Nano. The 1st 6 magazines would have a FTE (failure to eject or extract)so out of the first 30 rounds were Federal 115 gr. Then I switched to Lawman 124 gr. I was doing my conceal carry permit training the first mag of the Lawman ammo had a FTE. So out of the first 36 rounds there were 6 FTE.
A few weeks later I finished the box of Lawman 124gr with no issues. After working the slide back and forth several times and leaving the gun with the slide locked open for a week.I now shoot 115gr and have over 200 rounds with no problems.
I was originally wanting to buy a Shield but they were no where to be found at the time.
