Pachmayr makes several styles of stocks. As bananaman notes, the Compacs (displayed below in this nice photo I'm borrowing from Dale53) cover the backstrap (and give a little more length of pull). Google is your friend for determining best price today, but it might be better to go with one of the many reliable firearms accessory companies frequently discussed here. I often start my personal searches for such things by checking Midway USA and Brownell's.
