My hands are not large but I consider the Officer grip to be a hair short and this is an easy inexpensive fix. I decided to try a couple of Xgrip spacers on 8 round Checkmate mags for my ECO. They simply slide down the mag and lock to the base plate. They work just as advertised and extend the grip 1/2". Also catches the pinky and nothing wrong with 8+1 rounds either. I haven't tried at the range, but will this week. They also fit the same on my CCO.
I like them.
