Just started working on my own 75 Omega. Initially the trigger was quite rough with a DA pull weight that was over 18 pounds and a single action of 6 and a half pounds. Dry fired DA a 1000 times and the DA pull is down to 13 pounds and SA under 5. Still not what I want, but do not need to change much to make it much better. New 16 or 18 lb hammer spring (depends on which one will still be reliable with the Kadet kit), a reduced power firing pin block spring, reduced power trigger return spring and a probably a increased power (tanfoligo) sear spring (want a firm wall even in DA mode). All of this will be under 40 bucks and take an evening to install. May throw in a replacement firing pin retention pin just to round things out.
My two trips to the range were most satisfactory. 124gr ammo shot 100% reliable and to point of aim. Had two failures to extract with 115 gr ammo and both loads shot low. Oddly the Aluminum cased ammo shot reliably, but printed lowest of all.
May opt for a tritium front sight and paint my rear sight a flat black. Not fond of three dot sights.
