silver reserve
There are several at our club 20 & 28 ga. Lots of trouble -- hard trigger pull, doubling, saw one today -- would not fire the 2nd bl, tried again -- shooter pulled the trigger on the 2nd target -- nothing happened -- reached out and touched the barrel and the gun went off. Sporting Clays Referee would not let the shooter continue with the gun.
You should look at Yildiz (wide north web site) much higher quality than CZ at less $. Good Luck!
