So I met a dude at the gun show today, he wandered by my table looking for a Blackhawk .357 because he had a 9mm cylinder for one, and a huge amount of Israeli 9mm sub-gun ammo he wanted to shoot up. Well, I didn't get the ammo, but I got the cylinder, and it is for an OM. I now have a FT 9mm! It needed a tiny bit of fitting, just a little de-burring.

Be interesting to see how it shoots. Mine would do 6" groups at 25 yards with the 9MM bullets having rifling marks down one side.
