Keep your finger away from the trigger while unloading this or any other firearm. DC-9M are identical and all parts are interchangeable. A 6.5 inch barrel extension that screws onto the DC-9's threaded barrel. A soft cordura carrying case with three exterior magazine pockets. Used guns are considerably cheaper.
Used magazines seem to cost about the same amount as 'new old stock' pre-ban magazines.
Used DC-9s turn up occasionally for sale, but not very often. The recoil seems a little strong compared to some other 9mm handguns. The DC-9 seems really LOUD when I shoot it. A conventional short-recoil pistol directs virtually all of the noise straight out the barrel away from the shooter. The DC-9, however, is blowback operated and has large empty spaces inside the receiver, allowing a fair amount of the blowback gasses to escape from the correspondingly huge ejection port where the shooter will certainly hear it.
