You can't beat the Duty Treat for wear or toughness.
I have a DT VBob 45, a DT ECO 9mm, CBob 10mm, (custom all black), a custom 2 tone VBob 9mm, DT slide & parts, SS frame, A SS Ed Brown Special Forces carry bobtail in SS.
Like others may have stated, run them soaking wet, hand cycle hundreds of times while watching TV etc. If you're getting a 9mm Specialist use 147gr to break it in.
