Hey guys, I just sold my Taurus TCP the other day and bought a new PF9. I am going to the range in two days to "break in" my pistol. My plan was shooting 100 rounds of Tula 9mm 115g (steel) ammo through it, then 100 rounds of Blazer brass through it. Anyways, I was wondering if the steel ammo is really that bad through the PF9. I know it probably won't feed the steel properly, but other than being really dirty, will steel ammo actually damage the gun at all? Once I am through the 200 round break in period I plan on keeping Hornady Critical Defense in it for daily carry.
