I hope I didn't make a mistake here. I just bought a Nowlin Pro-Match drop in trigger job for installation in a gun I'm working on. That gun is at Tripp Research now, so I decided to try the kit in my Kimber Polymer just to check it out.

I would have to say that the Nowlin trigger job is "crisper" than the standard Kimber
parts but the pull itself seemed like it was about 6-7 lbs! That's just a guestimation since I don't have a scale.

The Nowlin mainspring was MUCH stronger than the one that came with the KP. I replaced the new mainspring with my old one and that helped a little. Maybe got it down to around 5 lbs.

I'm pretty sure my trigger pull with the standard KP parts was about 4 lbs. All I ever did to those parts was lightly mirror polish the engagement surfaces with jewelers rouge and a little felt buffer. I have put approximately 3000 rds through the KP with the original parts.

Will the Nowlin trigger job get lighter over time as I shoot it?

It's supposed to be a 3.5 lb. pull right out of the package so I am a little disappointed. Am I supposed to do anything to the kit besides just put it in the gun, like trim the mainspring?

The whole point of my spending $120.00 on this particular kit was to:

1. have good quality parts (non MIM) for the new gun
2. not have to have a gunsmith do a trigger job on it

I'm thinking now that I might have been better off spending the $50 or so it would have cost for McCormick parts (like those that come with the KP) and just polished them like my old ones and had a 4 lb. trigger.

Any one with experience with one of these kits or ideas on what might help, please let me know what you think.

The trigger slides smoothly in and out. It's not catching on anything.

I guess I maybe should wait until I actually get the gun (that these new parts are going into) back from the getting refinished before I pass judgement on them. It may be that they'll work better in that one.

I was just very surprised/disappointed in how the trigger pull was with the new parts, especially considering that everyone that posted on this board about the same kit said it dropped in and provided the as-advertised trigger pull from the get-go.

I guess if I do need to do more work I'll at least be assured that I used good parts and the trigger job will last.

I'll post again with how the parts work in the other gun.
