New CM9 from GunBuyer

[handlebar]

Just picked up a new CM9 with Black slide from GunBuyer.com for $289.00. I am not new to Kahrs, have owned them in the past.
I thought it was a good deal, so I pulled the proverbial trigger on it. I have not shot it yet, next Monday will be the first time I can get to the range.
I will report back with a range report. It feels good in the hand and the trigger is very smooth and predictable. It feels like my S&W 586 modified
double action trigger. Does anyone have experience with the MCarbo (3.5 lb) or Wolff (5 lb.) reduced trigger spring kit for the CM9?
Here is a stock picture.

Now THATS a purty gun. Congrats.

Purchased same gun few days ago, functions great, after cleaning went to range fired 75 rounds of standard 115 gr ammo, zero problems very accurate. Only change will be with grip and magazine extension. After purchase I applied for the Kahr rebate they approved it within a couple days. Perfect gun for carry in my opinion.

I have applied for the rebate but have not heard from them yet. I will get another magazine with the rebate money.

I also ordered a 7 round mag however it's on backorder they expect shipment end of this month.

I just ordered a 5 lb. striker spring from Wolff. I think 6 or 6.5 lbs. reduced to 5 lbs. is a safer way to go than Mcarbo reducing to 3.5 lbs. I think there could be some light strikes with
the Mcarbo even though they say it won't happen, plus a bit too light for self defense. I can hear the prosecutor now....should I ever need to use the gun.

I watched the MCarbo YouTube video on their Kahr spring kit. I'd never heard of them before, just Wolff and Galloway Precision. I would almost guarantee the MCarbo kit is going to affect reliability. If you watch the video, you see the trigger has a difficult time actually resetting. It comes forward to a point, pauses, then slowly returns to full reset.

That's a big no for me, dawg.

I don't think the Kahr trigger needs anything other than a good polish on the trigger bar and trigger bar spring and a touch of grease to slick it up, but the Wolff and Galloway kits seems like safer bets.

How do you like your Wolff kit?

I agree, the MCarbo is far too light. They have been around for a while and make lots of trigger lightening springs for a variety of guns. The Wolff spring gives a very smooth and controllable 5 lb pull, and reset is very positive. It is noticeably different than the stock spring and contributes to better accuracy because it breaks sooner. It was a good investment at $3.50. I am waiting on a recoil spring for my Model 52 but it is on back order.

Is this the same MMeyers from the Bullseye-L forum. On that forum I am Mustachio.

Is there a thread or video on doing a DIY Kahr trigger job?

This video shows how to change the striker spring which controls trigger pull. I used the Wolff 5 lb spring, not the MCarbo. I see no reason to change the striker block spring. I like the stronger spring for the block...adds a little extra "safety".

Yea I've done that with my K9 and K40. I'm interested in polish the trigger and trigger bar spring.

Not meant to offend but do not understand the need to change springs, adjust trigger on a quality carry piece, could cause you liability issues down the road. On my range /target guns I will do some trigger work but the CM9 is not that.

No offense taken, I shoot a lot of revolver and the original trigger on the CM9 was too heavy for my taste. I put in a 5 lb striker spring and it is now closer to a nice DA revolver trigger like my S&W 642 and my S&W 586, which is used as a target revolver with a 2 lb. trigger. A 5 lb trigger on the CM is still heavy enough to not go off unless you pull that long trigger pull and gives a positive reset. It is not too light that may be considered a "hair" trigger. That is why I avoided the MCarbo spring kit. Accuracy has improved, as well. If I ever use it for defense, which I hope I never have to do, my liability issue is far greater than a 5 lb trigger.

I've done that to my CM9. It's easy. My advice to you is make sure you hold onto the spring when you remove it. The polish and grease made a world of difference.

That video is lame, but it does show the disassembly process. I have the Wolf 5lb spring on my PM9, replaced the trigger bar and polished it with a Dremel before installation. The trigger feels good and I don't consider it too light. I would never sand down a spring like in the video, if it had visible wear, it would be replaced.
The hump on the trigger bar was flattened down a bit, looked hammered down. I also polished the top of the hump on the new bar.

The spring from Kahr had a burr inside the apex of the curve. That's part of what caused the creak.
