Failure to eject

Got my Tp9 SFX this morning - field stripped, cleaned, lubed. Have been very impressed by reviews and was looking forward to shooting it.

Shot fine, until, after about 30 rounds-failure to eject...occurred again in about 20 rounds....then ran fine for the rest of 100 rounds. Anyone had this problem....any advice, suggestions appreciated. After shooting, I stripped, cleaned, lubed again.

thanks from a new member.

One other thing....how do I tell which size the backstraps...all I can see on the one NOT on the gun is a 1 inside the backstrap...and don't you need a 1/8 punch to change the backstraps.

many thanks

You need some ammo with a +P rating in the stock SFX for breaking in the spring . Easiest way to get it is to go to Walmart and pick up a couple hundred rounds of Winchester 124gr NATO ammo. Sells for about $27/150. I bet your ejection problems go away. Contact Century Arms and request their reduced power RSA for lighter loads. They'll send you one free.

Should of come with the smaller backstrap on it.

I ran 200rds of 124gr NATO through first and didn't have any failures. The 300rds of 115gr random ammo afterwards worked great. Keep in mind that the higher power of NATO or +P is equally as important to break in rather than just 124gr ammo. Some have also had luck breaking in the spring a bit by leaving the slide locked back for a few days. Enjoy!

Good stuff. It's designed to perform similar to the Speer Gold Dot carry ammo, which is why I stock up on it. Keep us posted how your SFx progresses.

i am having the same problem with my sfx, 124 nato win doesn't eject after the first 10 rounds, should i keep shooting the 124s and just mess with it until it works good, i guess it would be good practice for failure

Lots of DRY FIRE! ...and I recommend a dummy round/snap cap in the chamber.

Start out slow, draw from a low ready and extend like you normally would to bring your sights on target, and your dot should be there. Make sure you have both eyes open and stay focused on the target. It's just a muscle memory thing. With a proper grip your support thumb should be pointing towards the target and help with the dot alignment. You want to bring the gun/dot up into your line-of-sight and not be moving your head looking for the dot. Basically putting the dot between your eyes and the target. Don't get frustrated!...you'll love the dot!!!!

The RSA should soften up. You can also contact Century Arms and they'll send you a reduced power RSA. When I received mine the paperwork stated it was an 18-18.5N spring. I use that one when I'm shooting my 115 range stuff. Sprinco is for low power sub-sonic ammo.

I've had the same issue but with much greater frequency. Just bought my TP9-SFT on Wednesday. Cleaned and lubed the weapon and took it to the range Friday. Shot 150 rounds of both 115 and 124 gr US made ammo. Had FTE and FTF issues every second or third round.

Any hints or help would be greatly appreciated.

What brand 124gr? FTE were stovepipes or stuck in the chamber? Feeding issues jammed up on feed ramp or before?

American Eagle 124 Gr. Blazer 115 Gr. Have looked at a bunch of comments regarding FTF/FTE issues (none as much of a concern as mine are) and have read that:
a) Try shooting a couple hundred rounds of Winchester 9mm NATO (+p)
b) Store the firearm with the slide locked back to try to take some of the stiffness out of the recoil spring assy.

I have also contacted CAI about the issue but so far no response.

When I fired the pistol on Friday, I got mostly failure to eject stoppages. The spent casing would stovepipe; sometimes sideways; sometimes straight up. the next round would jam between the feed ramp and the stovepipe casing. Had to remove the magazine, clear the stovepipe and sometimes reload the stripped new round back into the magazine. Sometimes when the casing stovepiped, the next round would partially enter the chamber, and clearing the stovepipe would result in the slide moving forward and fully chambering the round.

Also, on last round fired in the magazine, i had many issues where the slide did not lock rearward on an empty magazine.

Going back to the range tomorrow to try the NATO ammo.

Yeah the American Eagle 124gr isnt loaded very hot. My Elite was stovepiping multiple times a mag first outting when I tried to put WWB and Federal 115gr through it, switched over to winchester 124gr NATO and some PPU NATO and after a few hundred rounds it was broke in enough for 115gr stuff.

Its easy to ride the big slide release depending on your grip, sure thats not causing no last round hold open?

I don't think that i inadvertently had my thumb engaged on the slide release. I used the groove in the grip to rest my thumb.

I believe that its basically a very strong recoil spring coupled with non +p ammo.

I see where CAI has a weaker spring that it has sent to others with this issue. I will see what they say in their reply to my note to them, which I expect to see on Monday.

Thanks for all the help!! Appreciate your time.

After a couple hundred rounds of the NATO 124 Gr, I'll post my results.

Range Report

Shot 150 rounds of 9mm NATO through my new Canik.

Zero FTE. Zero FTF

Still going to see if CAI can send me the reduced tension spring.

My SFX new would shoot 115g win white box with no problem. My 124gn low power reload would not eject. Stuck in the slide sideways. I got a lighter spring from Century and tried it today. Now the gun will cycle ok with my low power loads.
