There were a real flurry of posts a while back about making the Kadet more reliable. And trying to explain why some work and some don't. I have read pretty much everything. But there are no consolidated recommendations by experts for minimum/multiple changes to consistently get a properly functioning Kadet.
My current perception:
Make sure everything is smooth and easy to slide.
Polish parts on the magazine (top and inside) and lube.
Potentially have a new firing pin made like the one eivind demonstrated in the
Extended Kadet Firing Pin thread that puts a notch in the rear of an extended FP to limit travel.
And that may not be enough. Or it may be excessive.
I would, and I suspect others would, appreciate it if the people that were really getting dirty trying to resolve various problems could provide a consolidated updated list here of recommended effective alterations. Some problems had multiple solutions. So filtering down to best practices would be very helpful. Essentially, a list of actions one should take when taking a new Kadet out of the box. I don't feel I should do copy and paste of the things scattered about. I simply do not have the expertise to select.
I have a CGW modded CZ75 SP01 Tactical that got their full treatment and would like to be able to use a Kadet sitting on the assorted changes made by CGW without fooling around with different springs, hammers, etc. I do not want to invalidate the work I paid CGW to do. I would really like to prep the Kadet so I can simply replace uppers to use either 9mm or .22.
You guys with crazy good skills out there, please think about working to a consensus on this thread for an agenda to implement on any new Kadet. It may fix issues that do not exist on any given kit, but after implementation it will make any kit a plug and play device. Sorta like CZ should do.
And if there is a consensus, it could be a good service opportunity for people out there who do this sort of thing commercially (CGW comes to mind).
