My P01 just came back Priority Mail from Matt Mink, where it went to have its ratchety trigger smoothed and a pair of night sights installed. The sights are big and easy to use in normal light. And - oh my gosh - the trigger! It's wonderfully light and crisp single-action and oh-so smooth double action, even from hammer-fully-down.
I haven't been to the range with it, but it has to work great there. The shooter interface is so much better than it was. If you are thinking about sending your gun away for this sort of work and you are concerned that a decocker gun will not respond well to his ministrations, set aside your reservations.
Didn't take a lot of time and didn't cost as much as you might expect. Recommended, bigtime. Happy Thanksgiving, Matt and all you CZers!
