x2 on what Dallas said about the hammer spring. So long as it is strong enough to dump the air in the valve (cock it again and pull the trigger and get no air), that's all it needs to do. Anything above that is just making the trigger pull more difficult. I don't rank myself a trigger snob but the Crosman direct sear trigger on the 1322, 2240, etc. is the epitome of mediocrity, so my advice is take care not to make it worse by leaning on the hammer harder than necessary.
