The work was done by my FLG who is a 1911 specialist and did this CZ as a favor during a slow spell. "No more." he says.
Anyway, the SA is 4.5 lbs, the DA lighter than stock but I don't have a gauge that will read DA pulls. The trigger stop is a set screw through the trigger; adjusted and then cut flush so as not to irritate the trigger finger. The front sight is a Novak on the .330"x.060" dovetail, finished as a plain post .200" tall. The rear is homemade by slotting the stock sight, soldering in a plate, and milling the notch. Drift and file to zero, it came out about .300" tall, a good .130" taller than stock.
The Kadet gives good practice, but.
It feeds and fires reliably (now that it has the "chisel pointed" firing pin upgrade) but stovepipes more or less frequently with all .22 lr I have on hand, even with the new ejector they sent with the firing pin.
