Gents. Finally getting round to replace my old .22 bunny basher & looking at getting back to a CZ rifle. Have narowed it down to the varmint in a 20" barrel, but i have since noted that there seems to be a new(er) version the 453 with a set trigger ?!. Does anyone have any experiance with either of these two variants & how did you get on with the set trigger ?. Is it like the old Mauser with the two triggers or a push forward on a single trigger. Many moons ago i used to have a CZ before i sold it & regreted it ever since hence going back to one now. cheers CM.
