Hi AJP
They are rarely on the market and Morini no longer make the pistol for the U.K spec with the rods at the back. I bought mine off the sales section on the Police Sports Shooting Association web site. I have seen SAM, Pardini and Morini free pistols advertised on there in the past but they are not on there for long.
Besides myself I know personally only three other free pistol shooters, three of us own Morini and the other a Pardini. The Pardini had to have a new extracted claw fitted, it had fired 1,000x? rounds and was by far the oldest pistol in the group, l don’t know of any other problems with free pistols.
Where are you based, when lockdown is over and if you can get to Oxfordshire you can try mine.
