How about reliability, reliability, reliability. How many P7's have you seen in a USPSA match? How many have you seen in IDPA match? Glocks are cheap and they run good for a really long time.
Why shoot the bejabbers out of your $1200 wunderpistole
, when a $450-$500 Glock is perfectly adequate for the job? Don't see many accurate and "reliable, reliable, reliable" SIG P-210's at matches, either. If there's one pistol on the planet more feed reliable than a 9mm Glock, the fixed-barrel P7 would be it.
If "how many you've seen at USPSA matches" was your criteria for choosing a pistol, you should sell those Glocks and buy some 1911's.
