I have a friend with a Ruger 22/45 that doesn't shoot, has no trigger (the trigger is there and moves but it doesn't do anything when pulled. Like it's not releasing anything) and we can't take apart. We can't get the mainspring out. When we release the catch it won't swing free. I also have one that is fine and we were using it as reference. In looking at mine it looked like the hammer wasn't in the correct position when he assembled it. After looking at it more it seemed like the pin that hangs from the hammer might be caught above the mainspring. So we are basically lost since it doesn't swing free. I tried to hammer the bolt pin to see if it would come down and hopefully free up whatever is caught on the mainspring but got nothing. He is calling Ruger to see about sending it in but I was hoping to get some info and saving him a few bucks. Thanks. Also, are there any local smiths in the worcester area that might be able to fix it?
