A 391 Urika 2

[savaloy 1]

Hi all, i have a 391 urika 2 sport, had it a few years, bought second hand, great gun, i shoot better with it than with mt 686, it cycles everything from 28gr up to 56 gm no trouble, even when 3 different weight cartridges in the mag, but certain cartridges it wont fire, lyalvales for example, now i presume they have harder caps in than say gamebore so i would just buy gamebore shells, but if we go claying somewhere & we buy their shells you never know what make they are so i get the problem. Am i right in presuming if i replace the " trigger spring" it will sort it? the " trigger spring" looks like it is the one powering the hammer? have looked on berettas spare parts list & theyre sold out of "trigger springs" so am thinking other people have been buying them ? has any one else had this problem. ive put a new firing pin in & replaced the piston which was the wrong one in it anyway.
