I have yet to read a good thing about the Vektor, never owning one though I guess i am not qualified to make any judgement on this action. That being said, again most statements made on the vektor have not been good, i.e. 375 and up only hold 3 rounds and some have questioned the quality of the metal used to build it.
I have said it before, if you have to have a CRF DG rifle, look at the CZ550's. They are incredibly accurate and very well built. Most have a pricetag that us mortals can afford as well. For a little more Ruger makes a handsome DG rifle, I love the look of that half barrel rib they are putting on the 458 lott.
Although not a lot of help, I hope you make a good choice and enjoy whichever rifle you choose for a long time.
