Just out of interest I have just gone through the process of choosing either the Kofs or Yildiz in 28b youth configurations. I had my wife handle both and whilst there was little between them we found the comb height of the Kofs to be better for her. So off to the local gun shop we went with funds to buy the Kofs, once there we received some excellent help and advice from one of the staff who told us that Yildiz have dropped their prices to match Kofs (£495), so I decided again to get my wife to try both but this time to try the triggers with snap caps. Well the Kofs trigger was so heavy I could see the barrels being pulled to the right before the sears released, the Yildiz was a massive improvement and that made the decision for me. Yes I know I need to raise the comb height by about 10mm but that's easy and cheap, but to try and sort a heavy trigger pull with no guarantees. Oh and the Kofs is 1 year warranty whilst the Yildiz is 2 years.
A big thankyou to Greenfields Gun Shop in Salisbury for their help as ever.
