There has been a couple other threads on this, wasnt able to paste any links for them though this am.
I contacted the various ammo manus directly (I have a PC Shield) and was given their suggestions on what ammo is or is not for ported use.
Seems Blazer said no, due to thin plating that potentially could flake off and exit the ports. Other ammo in their brand line is ok.
Seems the Federal brand was not ok but their American eagle was. Best to just check with the manu of the ammo you use to confirm what will work for your needs.
Edit: found the reply from Federal; not much for info but it was all i needed to know. Again asking them directly is probably best.
We suggest using the American Eagle 9mm ammo, do not use the Champion brand brass or aluminum in your ported S&W.
Thanks
