I've got some pics of the blued PLY and 21A for comparison:
I painted the front sight on the Taurus, crappy job, though it helps. The Beretta has even smaller sights. The Taurus feels bigger in the hand, but they are almost identical in size. The Beretta has more metal vs plastic in the frame/trigger guard areas. I removed the magazine safety on the PLY22 (magazine does not drop free either way), but I wouldn't want to take the grips off again. It was very difficult to remove as it's a one piece grip which locks? into the frame.
