Put 150 rounds of FMJ yesterday' through my new CM9. The slide failed to lock back on an empty mag for the first 3 mags, but then flawless. Used both the 6 and a 7 round mag.

Very accurate also for such a small gun.

Very happy with my decision to get a CM 9.

Do I assume correctly that the failure of the slide to lock back the first 3 mags through the gun is normal during the initial break in period?

Being left handed I had to adjust my grip on my pistol with the ambi stop cause of holding the slide stop down while shooting.

They are built to very precise tolerances. Sounds like yours is well on the way to being broken in. Happy shooting!
