but..........do remember that if you reload your own ammo, the contender can be had in many wildcat calibers that are nearly as, or just as effective as the high pressure chamberings for the encore.
the contender is slightly smaller and lighter, if that is a concern also.
in the field i use whatever's available to rest the forearm on..........or use a set of homemade cross shooting stix............and shoot with my left arm bent and the nylon sling around my elbow to steady the off hand shots.
all out offhand with no support of any kind will severely limit your range. practice extensively with various field rests. don't be afraid, or just plain too tight to put a lot of ammo thru that thing.
