If you're okay with minor PF on pistol, go with the 9mm. I've shot some real soft loaded 124gr loads (probably 127pf, real close to the PF floor) and factory 115gr loads (135+ pf), never had a problem with steel unless it was calibrated too heavy or I just didn't hit it in the right place.
The little 3-gun I've been able to shoot I shot in Tactical division (16" AR with Aimpoint Micro). I ran the same Glock 34 or Glock 17 I run in USPSA Production division, just load the magazines to 15 or 16 rounds. Eventually I'll get a few Arredondo extensions, but it's not a problem with the local matches.
One of my friends I've shot with runs a 1911 with 10 rounders and hasn't has a problem here at local matches either.
