i got a CAJUN OMEGA TRIGGER KIt for my 75B OMEGA for Xmas & installed it myself.
mine has a "issue" with not pushing the sear all the way back sometimes to drop the hammer.
It seems like it only does it if you pull the trigger really slow to check creep & hammer drop.
I called Cajun & they said it could be the roller size, try the stock one.
I put the stock roller in & couldnt tell a difference. They said they may need to drop a piece of solder on the trigger bar. They said to send it to them & for $75 they will tune it for me.
I'm not to sure i want to send it. I feel if your selling a $220 trigger it should work across the board & i shouldn't have to send my gun to be tuned fro an extra cost.
I noticed a difference in trigger travel in single & dbl action.
A little bit of difference on the trigger pull, it dropped some, but my stock trigger was pretty broke in.
...If I had the opportunity to do it again, I'd save the money and put it toward buying another CZ. But I'm one of those guys that thinks a stock CZ is the best shooting pistol he owns. It's all about personal preference.
