I do not own one yet, but looking for info before I order one for Christmas, I contacted Ed Jennings at Jennings Machine & Tool. He said the Mk V should work on the CZ slide. Jennings sight pusher is 1 of the favorites at the Smith & Wesson forum, so may be worth a look..... If anyone has experience with one on this forum, using it on CZ's, I would be interested in hearing about it.
