kimber slide stop problems

[frank8097]

So today there I was at the range breaking in a new kimber custom and I'd say about 4-6 times my slide stayed open with there still being rounds in the mag, what could this mean? As for the specs I was using kimber pro tac mags and it would only do this when I used the ranges reloads (if that means anything). Also everytime it did this the slide stop would be only partially in the gap were its suppose to go into.

Depending on how you hold the gun, you could be inadvertently bumping the slide stop with your thumb.

If that's not it, take a look at the slide stop and see if there are any copper marks where the magazine follower would make contact. If so, the next round in the magazine could be touching it and bumping it up during recoil.

You know that actually occured to me a little after I made this post and probably is whats wrong. I looked in side and seen no copper marks whatsoever, so I think you might be right, atleast I hope you are. What should I do if it is the follower?

It wouldn't be the follower unless the mag is empty. Could be a bad mag though. Feedlips spread too far apart. Allowing the round to flip up at the nose and catch the stop under recoil. But I never had that problem with 6 mags and over 5000 rounds in my TLE II.
Shoot with one hand and see if it still locks up. If it does, Try another magazine.

My first thought was the Mag, but you'll need to do some experiments to confirm or go on to something else.

[MicronuT]

is it a stock slide stop, or an extended one?

[frank8097]

Its stock the whole gun is stock. Also I'll check to see if my mags feed lips are impared in anyway.

[MicronuT]

hold the slide back to the lockup position, and fiddle it up and down, report back with results

take the mag out, before you do this

You said it only would do this with the range reloads. I don't know on your kimber but usually it means the ammo is contacting the slide stop. I would think it's either the bullet profile or the rounds are loaded long for your gun. Mark

[frank8097]

Ok when I pull it back without the mag in doesn't stay locked up unless I move the slide lock upwards, with the mag in it (without rounds) it stays locked back. Aside from that it all seems pretty normal when the slide lock is serving its purpose is real stiff no unusual movement. I think it all just may be what SarcoBlaster said about my finger hiting the slide lock at the right time. But I dont know Im kinda pissed.

I guess that makes sense it never occured to me to compared the rounds, well I hope your right cause I'd be pretty disappointed to find out I got a defective gun. Next time I go Im going to do this.

I don't have my kimber in front of me but the rounds hitting the slide stop is definitely an issue in my cz pistols. On both of them I had to file on the slide stops because my 147 grain reloads were making contact.

[frank8097]

I'll probably go to the range tommorow or sunday and will shoot only factory ammo the to see if it happans, if so I'll grid it down a bit BTW is good to shoot +p rounds through it? The reloads were noticeably more powerful than the non +p factory ammo.

[MicronuT]

more powerful? maybe a heavier load, shoot a few more hundred factory through it, and see what happens

[frank8097]

They were both 230 gr fmj's and the recoil of the reloads were more harsh. I dont recall, but I've read somewhere that shooting +p through a 1911 isn't good for it or something along those lines (how ever much truth that may hold).
