Jovino cut down square butt frames and round butted them. The problem is they fall somewhere in between a K-round and an N-round, and the cutdown job is sometimes lopsided. Also, some if not all of them had the main spring replaced with an after market upgrade which means where the grip screw goes through on a factory mainspring, now you have a spring blocking your screw. So if you want a nice fitting set of grips, I would recommend sending the revolver to a grip maker that has an FFL and can receive your gun and make a set of grips specifically for it.
