My first gun was a Kareen MkII.
It was an Israeli BHP clone and I was leaning towards a BHP, but this was $50 cheaper and had an extended tang and nicer grips.
Man - did those bums steer me wrong
The gun shot its self LOOSE in a few hundred rounds - it actually would not extract out of the box, but they fixed it at the store for free.
What stinks is that I had it for a long time and just figured I was a LOUSY shot because I could not keep them all on a target at 10-15 yards - not even close.
Later, when I had more guns and knew I coudl shoot, I still could not keep all the shots on a paper plate at 7-10 yards because the gun was so loose (and I mean LOOSE!).
It actually had a really nice trigger for a BHP and I sold it to a TFL member a while back and it more or less worked as a good lower for him...
Second worst gun was a Remington 547? HB - again, got steered wrong, should have got a 10/22, but this thing had a purty stock and a heavy bull barrel - this thing was a total jamma-matic. Paid some $400 with the scope, happily sold it all for aroud $250 after enough aggravation.
Third worst was a Colt Defender - it gets mention only because I liked it so much and wanted to love it, but it just would not let me. It was always JUST unreliable enough to make me nervous about depending on it. Bummer - it fit my hand, was fun to shoot and ACCURATE as heck. But even after I got it ironed out pretty good, I still did not trust it.
