I purchased the slip on front stock holder at a local sport shop. I found that it also gives an additional padding to the stock when shooting from box stand rest. I also had 2 ammo loops sewed on my jacket's left upper sleeve and on the left front (where a chest pocket would go). I found that both were easy to quickly access when reloading. I do not use both at a time, I found that one works better in a climber and the other at other times. I always use the front stock mounted holder. I used the rear stock mounted holder, but really did not care for it to much and took it off. I want to say that I paid around $20 for the front stock holder, $25 for the rear stock holder. I have seen the wrist mounted holder on ebay for around $15-$20.
