Khar pm40 issue

[mikeb3185]

when i insert a loaded mag and rack the slide, it stays locked back. i have loaded a mag and tried to rack all the rounds through and the lock back almost always happens.

if it helps:
there are zero rounds through weapon at this point

i am unable to break weapon down... did it once cant do it again

When your slide is released, does it sit flush with the frame like normal? Could be that the slide release was inserted when the notch on the slide and the notch on the frame did not meet. The slide might have been too far back. Then you have to extract the release forcefully with a flat head screw driver as a wedge between the release and the slide.

Also, to chamber a round in a PM40 you must lock the slide back, insert a full magazine, then release the slide using the slide release. Do not sling shot the slide to chamber a round. But I'm sure you already knew that.

It sounds more like the slide stop was inserted in such a way that the spring is now pushing it up, instead of down.

I don't think it's even physically possible to put the slide stop back in with the lines not lined up. You'd just end up putting an "idiot mark" on the slide.

Did your problem start after the first disassembly? You may not have inserted the shaft or pin of the slide stop through the kidney-shaped unlocking cutout in the bottom of the barrel. If this has happened it will be quite difficult to disassemble it again. Also, the recoil spring is directional. The closed end of the spring must go against the little flange on the guide rod.

Yeah, I'd have to say something's up with the slide stop. Did you line everything up properly when reinstalling it?

he has

to have that little spring on the slide stop in the wrong position. No other way for that slide lock to move upward on a loaded magazine, unless the rounds are actually moving the slide lever up and he should be able to look inside the gun when racking the slide to see if those rounds are hitting the slide release/lock lever.

as far as not being able to take the slide back off that is odd, for if you line up those two witness marks on the slide and frame/grip,you should be able to pop that lever right out. That even tells me that he has indeed got the lever under the spring which is now always trying to push the lever up instead of over it where it should always be trying to push the lever down. Only the magazine follower should push the lever up.

I would think he will have to line up those two witness marks and then with a small blade screwdriver pry the lever out,It should come out as the only thing holding it in place is the spring. Hopefully you have not damaged that little spring.

Sounds like when u took it apart u did not get it back right. Go slowly with the abouve recommendations and quite possably you have not ruined the lever spring.

A good way to see how that spring works is with the slide off, put the slide lock lever back in place only with the spring over the lever notch. Now if you did that, the spring should aways be pushing the lever downward. If u put the lever in with the spring under the notch, you will see the big difference. It now wants to push the lever upward and I think this is what is happening now with your PM40. very easy to see with the slide off and you will see how easy it is to improperly install that lever if you not careful.

I don't think he has the slide lock pin in front of the barrel lug, for then it would not rack at all. and the only way to get that pin out is to lay it on it's side with the slide lock lever facing down and get a wooden dowel and put it on the other side of the slide on the pin protruding and hit it hard with a hammer. U won't break anything or damage anything. It will come out OK.

hopefully u have not ruined the litt e slide lock lever spring...

I didnt read anything besides the first post.. but, if the pm40 is the same as a pm9, and the pm9 is the same as a mk9(???) anyway, the mk9 is really easy to field strip.. if you cant even do that, then you need to take it to a gunsmith

 

[mikeb3185]

hammer and dowel worked not sure if spring is ruined yet........ I WILL NOT MAKE THAT MISTAKE AGAIN

spring good.

thanks for the help

 

[jocko]

okay

now were getting somewhere. test out that slide lock lever /spring combination without the slide on. that willtellyou if the spring is ok. \

If so, reinstall "properly" and then rack the slide to confirm you got the lever unde rthe spring and not over it. It should always be wanting to push the lever down.

My main issue with the PM40 is that it's the best small concealed carry weapon of all time; bar none.

 

[jocko]

yup

thats the main problem I have with my PM9 to. best damn ccw gun I ever owned, 19,300 rounds downrange and looks new. Hell to have problems like that ain't it?????

 

[ScareyH22A]

^Are you serious? You've actually fired that many rounds through your PM9? Did you make a thread about it? BTW, have you guys seen the new PM380? I saw a comparison pic of what I believe was a PM9 next to it and it made the 9 look big! I'd still take a 9 over a .380 for punch tho.

 

[mikeb3185]

Jocko- yes, passes all function checks. still no live fire yet....

 

[jocko]

ScareyH22> no never made a thread out of it. I bought it for carry and it is my 24/7 carry gun, pocket and vest carried, never hosltered. I like to shoot it better than any gun I own and it has never faltered. I just got a P380 about 3 days ago and yes it is small and it is a scaled down PM9 in every detail I put 250 rounds thorugh it the first day and not one issue with 5 different brand sof ammo. It shoots dead nuts accurate to. I can't believe how good it shoots and how pleasant it is to shoot either. They have a great little 380 there.

 

[BADUNAME4]

Another big problem I have is that with a heavier than stock 22.5 lb. Wolff spring and 155 gr. ammo it's incredible fun to shoot. Quite a handful, but not painful.
Nothing against other small guns, but most of them hammer the crap out of my trigger finger as the trigger guard slams into my finger. Also, the PM series is about as small as I can personally go and still maintain a solid and secure grip.
I certainly do hope mine holds up over time. So far so good.

 

[ScareyH22A]

Hey Jocko, hows the recoil on the P380 vs the PM9?

 

[jocko]

let me

compare the P380 to the Ruger lcp 380 that I own and love and to my once owned 380 Kt's.

The P380 kahr is like nite and dayover both of the others. Recoil is recoil. It never bothered me ever but this kahr has a wide stainless trigger that does not pinch at all. It definitely has heavier recoil springs, I don't know the poundage but they are damn stout compared to the 9# on the Ruger and I think 11# on the kt's.

My bet this Kahr recoil assembly is 18-20#. I have a hard time even racking the slide, as there isn't much slide to get ahold of and again these sprigns are stout.

I'm OK with it but those stout springs certainly help recoil, as my brass from the Kahr lands about 4 feed at best from me, where my lcp 9# springs the brass just dissaapeared over yonder..

trigger pullis right at 7# on my trigger gauge and that is what kahrs states also.

This kahr unlike the Kt's and the Ruger lcp produces no SMILEYS on the rounds. I shot 5 different rounds including two hp rounds. (corbon dpx and 102 golden sabre) and pulled the rounds after firing that first shot, (a smiley is produced after the first shot). and the front of the bullets were untouched.

A big big score for kahr in that area for sure. As one stated to me awhile ago, smilieys are damaged rounds, not the way they came out of the box.

I don't compare the P380 to my PM9 for recoil as my PM9 is magna-ported and that changes the entire ball game. Besides one being a 9mm and the other a 380.

To me the recoil is the best of any pocket rocket 380 that I have shot so far and I never had any recoil issues withthe lcp or kts. It is just that if you read alot of kt and lcp owners shoot about 50 rounds and then quite due to recoil and finger pinch. I shot 250 the first day with this P380 and never felt tired but at the time I was out of ammo. Today I put another 100 of PMC fmj through it without a hic-cup. Just a very nice well made quality handgun and oh yes those dovetaied sights are awesome. They actually work..
