Son, we all buy what we can afford and I hope nobody flames you for your purchase. I think maybe you might post the problem with the pistol and perhaps somebody can help you, the Jennings Company out of business isn't doing you much good. There is a spot here on TFL about gunsmithing and fixes and I would venture there.
Your $5 purchase might have been a good one or one buying a fishing sinker but it isn't up to we posters to put you down. Hang in there and move on.............
