I picked up a used Citori Trap Plus and noticed that the trigger pull was very sensitive. I measured the bottom barrel trigger pull and it was between 1 and 2 pounds. The top barrel is about 3 pounds and I think that feels about right. Most threads I read are about wanting to lighten the trigger. Is there an easy way to stiffen up my trigger pull, (with new spring, maybe) that doesn't require sending it off to a gunsmith? Thanks, Mark
