failure to feed issues

[zapatito92]

whats up everyone, i recently picked up my 84fs cheetah and only put about 100 rounds through it (still waiting on a bulk ammo order) and performed flawlessly with great accuracy. since it is a relatively small gun i figured it would be a nice carry/nightstand gun so i bought a pack of sig JHP's loaded up one of the mags and leave it near the gun.

Last night something told me to test out the function of the hollow points, since i don't really have experience with them, i never really saw the point. Anyways so i threw the mag in and tried to rack back the gun, and to my surprise it failed to feed . i tried again and still nothing racked it back a third time and it finally went in. i thought maybe it was a fluke or something. took that round out and tried the next only to have the same problem. had this problem 5 times in a row upon inspection it looked like the head if the hollow point was started to split. i guess they kept getting caught and that's causing the FTF. tried another mag with fmj ammo and fed fine. does anybody know what i can do to fix this ? or should i just avoid the hollow point with this gun ?

in a life in death situation its not ideal to have to rack the gun three times just to load it.

Racking slide and shooting is little different.. better of firing at the range than just racking it... but still.. it FMJ goes all the way, but HJP goes FTF...

Might have to polish your feed or fire few hundreds of rounds first before doing any adjusting.

It could be the ammo as well...

I am sure calguns experts will chime in soon.

It's very difficult to diagnose a mechanical problem without some type of visual. It could be ammo related, it could be gun related, mag related or operator related.

I don't have any experience with Sig ammo, or know who makes it so Sig can put their name on it. When I had a 84 I never had an issue with hollow points.

[BoJackUSMC]

Certain guns dont like certain brand of HJP.. that's is why they always tell you to shoot few hundreds rounds of HJP rounds before making that ammo of your choice.

I had to polish the feed ramp on my LC9 to get the JHP and XTP rounds to load consistently.
You can get a decent inexpensive dremel kit at Harbor Freight tools but be sure to get additional soft cotton rotary wheels for the feed ramp.
Do not use a grinding stone or sandpaper on the feed ramp.
Get a small container of metal polishing compound as well.

If you are going to polish the feed... do it little by little...

My lcp and lc380 both hate jhp rounds as well as flat nose rounds. Maybe something to that.

OP,
This reads like an ammo problem. Feeds and fires standard ammo.

Some pistols just gag on certain types/brands of hollow points.

Shop for several types and re-test. You'll find something it likes.
Please do not attempt to polish or "fix" it yet.

Same family as my LC9.
I bought the LC380 and waited for the LC9 conversion kit.
Loaded both .380 and 9mm FMJ no problem, but the hollow points hung up on the feed ramp.
Polishing both feed ramps solved the problem.

What are the liabilities of polishing the feed ramp?
Increased loading efficiency is not a liability in my firearms.

I would be concerned if the gun will not load a round from the magazine with simple racking of the slide. It is true that firing is very different but still. I would first change ammo bullet design. If that does not work then I would consider a feed ramp polish. Remember, once you start this only polish and don't remove or change the ramp angle.

If this problem persists I will probably just try doing that.

Thanks for the input everyone, its really appreciated Im going to do what bojack recommended first just try firing a couple hundred more rounds through it and then switching hollow point ammo like some one else mentioned
hopefully that solves the problem, if not I guess I will do the polish

thanks again guys

I agree. A gun needs to have at least 500 rnds through it to break in. But do try other brands of HPs at the range as well.
