Thanks for posting. I ordered one and was delivered this morning. Seems to be good quality.
I elected to install the KNS left side safety and keep the CZ factory on right to keep that side low profile as I am right handed. The install is easy, if you have already switched from de-cocker to the safety you should have no problem.
One item of note, you need to use the detent spring and small flat detent "piece" from your factory safety. If you install the KNS safety without doing this there is no click when actuating the safety. KNS did provide and extra one of these small detent pieces in the packaging but not an extra spring. So I would use caution when installing as these are under tension and can go flying off if you're not careful. Both of these will drop right in to the KNS safety so it's not a big deal but a small note or directions in the packaging would be helpful.
All that being said the extended safety does make a world of difference over the factory. Once installed it seems to function as expected and makes the actuation of the safety much easier. No range time yet but hoping to test soon.
