I had Peter Dunn of Wade's Eastside Gun Shop in Bellevue, WA replace the barrel on my recently purchased Detonics Combat Master. I highly recommend this shop and Peter Dunn in particular for his excellent skill and workmanship. He was fast, helpful, and produced fine quality work. I'm very happy and recommend his work absolutely. Peter's workmanship is superb. I don't believe it's often that we have the opportunity to have a gunsmith of this talent and experience with a particular gun available. Don't wait guys take advantage of Peter Dunn for your Detonics work.
