I've been using the RCBS hand primer for 9, 357 and 45. It works great.
There is some finesse involved with small pistol primers though. Every once in a while one will get turned around, go sideways or get stuck. Not a big deal, but it throws off my rhythm. If it happens, I take a breath and disassemble it. Only happens with small pistol primers.
Mine has the round tray, I'd like to try the diamond shaped one because I think they'd funnel the primers a little bit easier.
