My grandfather had one of the old ones and he gave it to my brother-in-law. It jammed incessantly. Called Ruger, they basically told him that they quit making the gun years ago because of a design flaw leading to the problem and refused to fix it, only give him some credit towards a new gun. Of course it was an heirloom so he said no. The local gunsmith said if Ruger wouldn't back it up he had figured out how to fix the problem, and he did and it is a fun little gun now.

The gunsmith said the newer ones had the problem corrected, it was only the first run with this problem. It really reduced my opinion of Ruger that they knew it was a design flaw and wouldn't cover a fix.
