Hi Slotbike, I like my 44, but when I first got it, it was a battle to get it to work right.... I learned a bunch....
1. The article listed above is excellent ! Save it or better yet, print it.
2.Ruger was no help at all... :x (They seemed offended that I would even ask them.....)
3. Give it a very good cleaning and lubing...make sure the gas port in the barrel is completely open. If some yahoo shot lead through it, it will plug that gas port. Even a partial plug will make your gun unrelaible.
4. Shoot only jacketed bullets.....down loaded ammo may be unreliable..
5. Some of the guns have an adjustment to help control how fast/hard the gas piston bumps the recoil mechanism. It's a small hex head screw adjustment that is directly in front of the gas piston.... If you do a search, there are instructions on how to adjust this. If you can't find it, let me know as i can send you the link. ( PM me) Mine was loose and out of adjustment. It's easily adjusted and then I put some Blue Locktite on it.
6.So far everything I've mentioned is easy and cheap to do....and will most likely get you up and running !! :)
7Unfortunately, that wasn't the case for me.... When Ruger made the early models of this gun, they designed the trigger assembly group with a protruding lip in the front, to hold the assembly in place. This lip was made of cast aluminum.....poor design ! Mine had broken off ( before I got it) and someone used JB Weld to glue it back in place...It lasted for ~ 20 rounds...bummer. After much ado, I was able to find a replacement at Numrich Arms. They sell an improved ( newer ?) version that required some gunsmith machining to adapt. It's a better design and the gun has worked well , since!! (From your description, I DO NOT think that this is your problem...fwiw)
8. I really like my little carbine and expect that you will too, but since Ruger won't support it at all........just know that you are on your own at times......
9. If you have any questions, feel free to post or PM me
10 Enjoy your gun !! It's a neat little gun !
