After owning a Sig and having its trigger system fail under range conditions for reasons which were never fully explained, I will NEVER own another Sig.
Step up to a REAL handgun, an HnK USP45. Put thousands of rounds through mine, not a single failure. Not one. Was at the range with it this past Saturday and was reliably hitting center mass with less than 1/4" difference between rounds at 45-50'.
People who know shoot HnK.
Yes, I'm an HnK bigot. :-)
