CW9 Thread Disappeared

[LampShadeActual]

Hum. My CW9 thread disappeared overnight. Now I understand why I never saw much real function/nonfunction information when I came here for research. Makes it hard to find info on the internet when what people look for gets deleted immediately.

I doubt that it got deleted. Sometimes, for whatever reason, even though I am usually careful, a post I am sure I made never shows up. I'm usually pretty computer savvy, but apparently sometimes get distracted . . . oh, look at that . . . http://home.mindspring.com/%7Ejustsomeguy/icon_lol.gif

If you post again, we will do our best to help . . .

Oh, and Welcome to the forum!

Edited to add: And you can just reply here if you like. Changing the title in your first message will change the title for the entire thread, if you like. Otherwise . . . thread drift is the norm. :rolleyes:

Thank you for your kind welcome. No mistake though. My post and its half dozen replies are gonners. Too full of facts, I guess.

I found your original thread interesting and quite damming of a gun you report that you like very much. I don't recall how much of what you wrote was genuine Kahr malfunction and how much was preference buffing. Much of the poly shaving and roughness wears out during breakin, but your expertise and experience lead you to do the buff and fluff that may not have lead to a malfunction. I'm not complaining as I did a similar although much less professional job, but my PM9 has shot perfectly except for the first few mags at break in.

I'm more interested to read a bit of tutorial on how you did each fix. We have some very knowledgeable folks here who have been smithing a long time and together you could offer the forum a lot. That is as long as you don't turn it into a Kahr bashing thread. Yeah they aren't all perfect but they are overall pretty darn good.

Excellent observations. I would note the shelf under the barrel hood was a show stopper. 4 different magazines fed so that hollowpoints caught on the shelf. The magazine follower problem and mags coming out was not recognized when it happened early on, but with the damage to followers, would have resumed at its own pace.

You are correct in that I did not want the pistol to fail. I wanted it to work. Nothing I did hindered working and everything kept it working. The trigger shape issue is what happens when a 6'3" 220# guy tries to use a small gun with a rotating trigger rather than a swinging one.

But this is sort of academic when the post thread disappears.

In a spirit of cooperation, I'll re-put the list of "fixes" here:

Things it took to make it 100% reliable:
*the rounded top front of trigger turning down cut my finger on first magazine. I removed metal, reprofiled the part that acts as a trigger stop in the forward motion, smoothed the part that rotates down away from the frame when you pull the trigger. If you have large hands, it rotates down and cuts your finger. A Kahr person on the phone said the worst that happens when you remove the trigger forward motion stop part of the trigger is that the free pull lengthens slightly. No harm by changing it.
*inside of trigger guard was rough cast plastic where your finger rubs as you pull to the rear. Polished the plastic so as not to retard my finger coming to the rear.
*disconnector was eating plastic in rear where upside down U is located for slide contact. Harbor Freight Mini-Dremel did its magic removing burrs from the stamped disconnector/trigger bar part. Burring stopped.
*magazines would not drop free when mag catch released them. Mini-Dremel removed burrs from the trigger bar reduced dragging on the magazines. Helped, not the full answer. They would mostly fall free.
*barrel had burrs all over from factory machining. Mini-Dremel neatly smoothed the sharp feathers and polished corners for smooth operation.
*striker tang-firing pin "sear" burred on bottom making a catchy draggy pull. Polished it with 600 grit paper backed with a flat stone. Much improved pull without a late in stroke catch.
*hand cycled the action 200 times just to loosen up the system and identify spots that rubbed.
*fired 200 rounds of WallyWorld WW115FMJ perfectly. Zero malfunctions. Every time, I loaded 7+1 to stress it as much as possible. Worked perfect. (Except for mags dropped out 2 or 3 times for unknown reason at the time. Worried me, but it never did it again. Remember this for later.) Thought gun was good to go. Time to test hollow points. Wrongie when I switched to hollow points.
*Where the barrel hood meets the chamber at top, there was a machined ledge about 1/32" tall under the hood upon which every brand of hollow point would catch and not enter chamber 3-4 shots out of each 8. Speer Gold Dot, Federal HydraShok, Winchester PD something, EVEN Hornady Critical Defense would hang up on it. Solution equaled you guessed it. Mini-Dremel away the L_ of the ledge and made it into a /_ if you get the idea. Polished and deburred the entire rear end of the barrel and hood in any place where a bullet could possibly come in contact. In Colt .45ACP terms, it was throated and polished. Also polished the feed ramp and rounded the bottom corners where they were getting burred on something.
*result equaled perfect function with any hollow point. Since the ledge was reshaped, it has now eaten perfectly, feed/fire/eject, about 500 rounds since the above fixes. When the ledge went away, no more catching bullet noses, the thing works perfectly.
*magazines dropping free when the mag catch was pushed were problematic. Found feathers from casting the plastic frame hanging inside of plastic handle holding mags in. Defeathered handle inside and mags drop free.
*finger grip extensions were an extra lump in my pocket in a pocket holster and felt funny under my finger firing??user concern, not defect. I reshaped each magazine so as to eliminate the little finger hook. Just enough to match the slope of the plastic above the little hook. Not a radical reshaping, just enough to get rid of the projection and blend the profile into the magazine tube and bottom plate. It felt better firing and stuck out less carried.
*sighting in was a trip and a half. Rear sight destroyed a couple expensive brass drifts. It was simply too tight for any gun sight. Finally had to shape a steel punch to move the rear sight without hurting anything before the rear sight broke loose for proper adjustment. To move one you have to put the slide on a firm but non maring surface, use a steel drift, and wack it a good one. Not precise, but I got it perfect.
*the CW9 is now zeroed for Hornady Critical Defense 115 FTX ammo. It shoots about 1" high at 15 yards. Same sight position works with 115 WW FMJ. Same sight position works with 4.1 Bullseye, Hornady 115 FMJRN reloads. All three loads shoot to same zero. This is the factory ammo sight height selections which have to use 115 grain ammo for an elevation zero.
*heavier and heavier bullets shoot more and more to the left and up. Hornady's Critical Duty 135 grain 9mm is close to the three loads above because it is kinda slow for a 135 grain 9mm. Standard 147 9mm loads move left and up quickly. Never shot any +P as no need with the Hornady Critical Defense ammo expanding and holding together to penetrate well.
*so having 500 rounds through it with zero failures since all the fixes were done, I thought I was finally good to go.
*then I ran accross a "warning" about the magazine follower internally disconnecting the magazine catch as there were 4 rounds remaining and/or again when there were 3 rounds remaining in the magazine. The follower goes by the mag catch slot in the magazine and in going by pushes the mag catch out of its slot in the mag. This is aggravated by the twisting effect of the finger grip extension floor plates. I read this note and said, Naw, not mine. Wrong again.
*follower problem details: See: http://kahrtalk.com/showthread.php?t=1612 (http://kahrtalk.com/showthread.php?t=1612) I stripped my six magazines and found the four original ones I bought at purchase chewed up with plastic sticking here and there. The two newer ones were beginning the process of self destruction.
*There is a simple fix there. I sanded and polished away the chewing making a 45 degree bevel sort of rounding and hope that stops the chewing. Pretty much on the order of the pictures in the site thread referenced above. It at least removes plastic material sticking out into the mag catch slot. The chewing up of the follower in two spots seems a constant process until the follower no longer contacts the mag catch. Something to watch for in the future as I clean magazines. I had no interest in grinding away any more than it took to uniformily smooth the chewed up places and round the areas as in the referenced site. Test firing reveals no problems in do this.
*the finger grip hook on all my mags is gone now so as not to contribute to the inadvertent release of magazines by twisting or by pulling down on the hook. I like them better that way anyhow. Some people like the little hooks.

That's the list. Mostly I would be reminded of a good quote I have always liked:

"Quality is remembered long after price is forgotten." LLBean

The forum seems to have problems with threads dropping off lately, not being deleted. Look at Jocko's and others, post count......strangely they will just vanish. It has happened to me too. Internet gremlins......?

post count was droppped in numbers by my request. I just kinda bothers me to see me with over 10K in posts,Kinda gives me a feeling of "no life". and IMO when a new poster comes on board I don't want him looking atmy 10K post count and having any fears with me. I am one of the guys here. I have never like post count, so the count being dropped back was by my request.

IMO there are some threads to that indeed need deleted. This fourm went through some ruff times about a month ago and our Mods got it back rolling straight again.

I have had threads dropped in my years here and upon provately inquirng, I was told why. remember we are guests of this forum, ur 1st, 2nd, 3rd or 4th amendment rights don't come into play here.

no offense meqant , just my comments.

[jeepster09]

Oh I don't take offense, I thought it was a technical problem, not a person problem. I agree on the "we are guests here". ;)

[LampShadeActual]

"no offense meqant , just my comments" It was hard not to notice your comments in every thread over and over again when I purused the information available here. Likewise in the deleted thread, your calling me/my original post essentially a liar was hard to miss. Being present all over the place doesn't mean contribution. Sometimes having nothing to say is best done silently. If the number count embarassed you, imagine how wonderfully the posts were received by the other fellows. Tough to sugar coat it.

On the issue of deleting threads that don't sufficiently promote the product, my thought would be what's the point of bothering to keyboard info and answers when they get deleted without a single word of explaination? Whilst I wrote the original in plain declarative English, it certainly was not misleading. It certainly was accurate.

It certainly reflected the actual angst a purchaser would feel with his first Kahr that needed this and that done to it. The deleter might be surprised to hear I actually edited it several times myself to make it more factual and less pizz-off-ed-ness. And away it goes anyhow. How more accurately does one say, "I was disappointed but worked through it one by one."

Okay, time to impose the "be nice" policy. Thread locked.
