Wolff Striker Springs in my 380 and 9mm

[ulflyer]

Put one in each of them and test fired a box each. No issues. But honestly, I could barely tell the difference in trigger pull. Maybe if
one were a serious target shooter, it might help. Who knows? Anyway,
it was a good exercise on taking the slide apart as I had not done that
before.

I just put one in my CM9, and it reduced the muzzle-dive at the break by about 50%. But that means there's still 50% of the muzzle-dive it had to begin with!

I'm mostly bothered because the PM40 I used to own had the sweetest DAO trigger I've ever shot. When I bought this CM9, I assumed it would be just as good.

Galloway offers a package deal for the striker spring and the blocker spring. I may just buy that just to get the blocker spring and see if that eliminates the muzzle-dive completely.

I've polished up most all of the trigger parts that rub and it helped a bit. This trigger is going to get better or else.

If I don't fix this trigger, I'm going to change my name to Kahryours.

As Yoda would say, "The trigger good it is. It's the shooter who needs to better get." Use the force, Kahrmine! (With apologies to Luke Skywalker.)

I'm familiar with muzzle flip/climb/rise but this is the first I've heard of muzzle dive. The word dive is descriptive so I know what the poster is saying but unlike muzzle flip I'm not certain of its cause. In context of this thread I'm guessing it is somehow caused by a heavy trigger pull, is that right?

Can muzzle dive like muzzle flip be somewhat reduced/mitigated by a good grip (and maybe for dive trigger pull)?

[wyntrout]

Anticipation of recoil and pushing the pistol downward to compensate. You must have seen someone pull the trigger on an empty chamber and seen the muzzle dip. A good trick to see if YOU're doing this is to have someone load a few snapcaps in a magazine along with live ones at the range. A LASER sight shows what the muzzle is doing through trigger pull, too.

Oh... and the only problem I had with the reduced 5-lb striker spring was with my PM45 after almost 5 years. I got multiple strikes on a couple of the cartridges without firing and then those carts went bang with my G21 SF every time. I put the standard spring back in the PM45 when I cleaned it just in case that was the reason.

It could be that Kahrmine isn't holding high enough on the grip in which case he would be pulling slightly downward on the trigger instead of straight back. Make sure that the web of your strong hand between the thumb and trigger finger is up tight on the beaver tail and that your finger is centered on the curve of the trigger, Kahrmine. It could make a big difference.

buy some damn snap caps and throw a half doxen in with 30 rounds and let someone load ur magazine so u don't know if u have one or 3 snap caps in the magazine. I guarantee you this will show u ur shooti8ng ways. Dryt firing is nice but it proves nuttin for you know there will be no bang thing happening, but with mystery snap caps in the magzne, it will show ur anticipation of the BANG THING. the anticipation and the bang happen at the same time so u really don't realize what ther fokk ur doing wrong but when you hit that snap cap and expect the bang thing to happen tha tis when u will jerk the trigger of the gun and shoot urself in the foot...

I realize over the interwebz the only natural assumption is that the issue is the technique of the shooter. I'm familiar with DAO trigger action, though, and have successfully owned and shot many DAO handguns over the years.

This particular CM9 has had an especially heavy break which when pulled draws the muzzle straight down. I would bet the trigger was 10+ pounds, though I don't have a scale to check it.

It's getting better. I have the lower weight springs on the way. I will report back after they're both installed.

[muggsy]

I believe that the average weight of pull is about 7# for all Kahr pistols. With the 5# spring and a little polishing my CM9 trigger breaks at 4.5 pounds measured. My old man used to say that it's a poor carpenter who blames his tools. Give the gun a little range time and/or do some dry firing. The more you shoot the gun the better it will get. At least that's the way it works for most Kahr owner. Patience is a dying art form in America.

I've dry-fired it thousands of times. Additionally, I owned a PM40 which shot beautifully, among other long, DAO trigger handguns I've owned and shot.

When I say it shoots low, I mean off the paper and into the dirt low. I had a second shooter try it with the same results. This trigger came unnaturally heavy out of the box.

I've found that shooting in to the dirt is a waste of ammo, and time, personally, I've NEVER had a firearm that shot in to the dirt. Sounds like a lot of user error to me. People with lots of shooting experience would never shoot in to the dirt, no matter what firearm they were using. It's never happened to me, and I've been shooting for 40 years.

I've read your other thread and it sounds like things are improving. But if the trigger pull is/was indeed over 10lbs as you described, I'd think a trip back to Kahr is in order. It's not that you shouldn't be able to accurately shoot a 10lb trigger (there are many good guns that come with 10+lb triggers out of the box) , it's just that a Kahr should come with a 7-7.5 lb trigger and something is wrong.

I know you are well on your way to resolving yours Kahrmine so this post is more for others who might experience an abnormally heavy pull. Thanks!

I agree I should have sent it back, but I had the week off and took the time to open it up and try to resolve it on my own, which I have.

Between the lower weight springs and the sanding and buffing, I shot a bullseye on my first try yesterday.
