P45 wont extract unfired round?

[Husky44]

Had the same problem with my CW 40. Sent it back to Kahr, they did some work, and it's better. They weren't clear what all they did in their writeup. I agree with the poster above who talks about the width at the tip. That seems to be the issue.

I didn't explore the length of the ejector; that's a plausible explanation as well. IMHO, the easiest fix is to do a little work on the barrel hood. Just be patient, and go slow, testing often.

do you think you will have to put a secondary bevel on the inside bottom edge of the ejection port as well to help the case clear?

[CJB]

What relief cut in the slide are you referring to?

The PM45 has a cut in the port that extends forward of the locking shoulder.



That cut is there to make ejection possible, as the rearward motion of the slide is rather limited. An empty would come out just fine, but to eject an unfired cartridge that relief cut has to be there. The geometry is slightly different, due to the longer amount the slide can move with a longer barrel, so the cut is not needed.

This is also done on Colt, Kimber, etc etc, in the 1911 designs. When the barrel gets short, the slide cannot move so far back without hitting locking surfaces, so its stroke is limited, and the cut is needed.

Just a thought....

Great postings! A good thing to keep in mind!
Thanks

Check the length of the EJECTor....

The only "problem" I can fathom is that the ejector is sitting somehow too far forward, may need "adjustment".

Is the position of the ejector adjustable or must it be filed to move it back?

The last thing I would ever do is to modify the ejector. Leave those kind of modifications to the Kahr Factory. Just my opinion. You could be opening up pandorah's box.

While I do appreciate your caution, my question remains. Is it adjustable or, must it be filed to move its position?

Ditto. Definitely discuss with Kahr. Wasn't suggesting a mod... just suggesting a possible cause. Dunno if the noses on the ejectors are hand fit...but looking at my PM45 here on the table... its a rather complex set of angles and cuts.

Since its pinned in... not adjustable except through modification.

any callto kahr about any "in house mod" they are going to frown on it. Not telling u what todo, but certainly I don't feel u have a real issue here, Change ammo brands as u suggested the otrhers u tried worked, Maybe in time this one round might work OK to. things seem to change with a gun going bang alot. Ur issue is not with ejecting fired rounds either, now that would be an issue. Some guns all being the same model etc, can be sometimes alittle ammo finiky. Kahrs are not normally ammo finiky, In ur case I don't see your kahr issue as ammo finiky, but that is ur call also. I certainly would find a good defense brand and stay with it. My P380 was a real bastard with 102 grain golden sabre ammo, some never had issues with that round. I don't either now, as I just changed defense rounds and stayed with it. At best I would do what GB6491 stated and some excellent polising of his marked areas will do no harm, no foul. Do to much and then send it back and kahr is gonna seriously frown on this, as again we are not totally certain it is not a overly tight extractor or ejector.

IMO leave well enough alone, to may other great brand sof defense ammo out ther eto get to excited over one brand that is not right.. fror ur gun.

At best if u just absolutley can't live with what your seeing, a calltokahr and asking them if u send the barrel back only can they do the barrel hood mods that ur seeing on new 45's They ight indeed do that for you and u wo't be out hardly any postage for a barrel that can be sent regular mail. Personally if it wasmy 45, I would pass on that to. Sopmetimes a change produces NEW CHANGES

Thanks for your thoughts, Jocko. I realize my issue isn't a deal killer with this gun but, it so happens I use Federal HST in all my other SD guns and would really like not to have to go thru all that testing again to come up with yet another SD round.

I think I'm going to call Kahr on Tuesday (after they sober up) and see if they might be willing to bring my barrel up to the current revision. Can't hurt to ask. Have a Happy, safe New Year.

While I realize the photo is in the failed position, it looks to have at least another 1/8" of rear movement before it hits the stops. I wonder if the bullet nose is hitting the barrel shroud where it is not relieved or the front edge of the ejection port when the slide fully returns as CJB suggested. Since it is only occurring while hand cycling there likely aren't enough marks either place to tell the tale but obviously a little something has got to go. Dremmel or 1-800, depends on your level of comfort.

Having seen a few guns go 'boom' instead of bang, I'd be sure to take a good look at the overall length of each and every round that takes a nose dive into the ramp, shroud or slide, even hand cycled. Pushing that bullet back into the case a bit can get everyone's attention!

Similarly, I'm not sure how many of those LSWC's I would be comfortable pushing through the polygonal barrel of that P45. They are said to lead foul very quickly resulting in increase pressures. I have used four Glocks in competitions for many years and yes, I 'rolled my own ammo' but I leave the lead castings for my grooved barrels. Just sayin'...

First, in response to your comment about shooting lead in the P45 barrel, I don't plan on doing it. I just used the LSWC in my test to see if the gun would eject a loaded round.

As for the slide still having 1/8 inch more of rear travel, it will not go back any further once the round contacts the barrel hood. i.e. the gun locks up tight. The slide will, however, go all the way back if I want to slingshot a round into an empty chamber from the magazine.

[TennSCN]

RK, if I understand, the magazine is out and the ejecting HST is becoming locked by the three points of the hood, ejector and extractor?

That is correct except that the round will become locked whether there is a magazine installed or not.
