I´ve asked the Interior Ministry to send me the statistics from the year 1990 to 2010 to check it.
But it seems that at least in Austria the toughening of the gun laws had a good deal of an impact in reducing the low homicide rate to an even lower level.
I have received the data now and made a chart:
And indeed, the (completed) homicide rate fell by 34% after the tougher gun law went into effect in 1997 !
Gun control is great ... 
Congratulations! I'm glad your country is doing so well. I guess it's easy to have such a robust social welfare system when you have so much profit from selling guns to the world.
*cough*Glock*cough*
What we need to see is a graph of Austrian handguns used in completed homicides in America.
Sorry. I had to point out the the elephant in the room. 
Yeah, Glock ...
It's a FPÖ-guy, what do you expect ?
As for the gun homicide numbers, it's also in the Interior Ministry report:
Out of the 162 total homicides cases last year, only 18 involved a handgun. 61 cases involved a knife, 14 a blunt object and the other 69 cases involved strangling, poisoning and other methods.
When we look at the year 1994 for example, out of 185 total homicide cases, there were 46 cases that involved a handgun.
2010: handguns were used in 11% of murder cases
1994: handguns were used in 25% of murder cases
The trend is pretty clear !
