I just inherited this Astra from my father-in-law. He registered this in 1968 but I have no clue who he bought it from. I believe the first time it was fired in the last 30 years was this past Saturday when I took it to the range. I have cleaned it up as well as I could (took it to a gunsmith by my house and he said he couldn't do much more with it at this point), but I did have some issues while firing it. About every 2nd or 3rd round, I would get a stove pipe shell. What could this be from? The spring appears to be pretty good in force, but as I'm not familiar with this pistol, I don't know what to expect. The magazine is only holding 8 rounds and I am reading that this should be able to hold 9 - but since my magazine doesn't appear to have some of the markings of others that I have seen on this site, perhaps it's not the original? Would a new magazine help?
Thanks in advance!
