I had a Rohm Twinmaster that was my favourite pistol until one day the frame blew making it a right-off. Decided to buy a PP700W and although it was quite good out of the box I found there was a few flyers. This improved by turning down the power to 4ftlbs and polished the trigger but still not quite as good as my Rohm was. Anyway having read this thread it dawned on me that I still had the Rohm barrel and some carbon tube so I re-machined it to fit the PP700W and now at full power it is dam near as accurate as my Steyr LP50 !!
