I have the Z sport and have for about 5 years now,thousands of rounds though it. Only had one problem because it came with mechanical triggers,had it fixed. They are alot more popular in the USA then in Canada.
I have the Zsport,which is the older model, the new Kronos which is a z gun but cheaper triggers ect,they brought out to compete with less expensive guns.
So if you can find a Zgun get it. Cole gunsmithing in Maine will mail you parts ect.,they are a good source and have a web site.
As I said exellent gun,well made,make sure it fits and you wont be disappointed.
My thoughts.... cooner
pm me if you have questions
