Absolutely. I have a P9 and a first gen P9M and owned another first gen P9M that I sold to a friend. All three shot as well as either one of my FN Hi Powers.

As clones of a pre Mk II Hi Power they have the humped rather than straight feed ramp. Some folks report issues feeding some hollow points. However, I have never had any issues with mine using hollow points that varied from the truncated cone shaped Hornady XTP to the RNFP shaped Golden Saber.

If you do have issues, a competent Hi Power gunsmith can remove some metal to give it the straight configuration.
