I just recently purchased a Kimber Aegis Elite Custom in 9mm. The first owner just bought it in November and it has less than 200 rounds through it. The trigger feels a little gritty but I’m hoping that smooths out after I run more rounds through it but the trigger breaks at 5.5 lbs which is a little higher than I would prefer. My question is if I retained the factory sear and hammer and have them modified by a good gunsmith how much better can I realistically expect the trigger to get without replacing the hammer and sear with aftermarket parts? If I could get it around 4lbs or less with a clean break I’d be a happy camper. If that is not realistically achievable then I won’t waste my money with modifying the factory parts and go with aftermarket. I would prefer to modify the factory parts to save money. This will be a range gun only.
