eaa witness poly p, fail to fire
I have a newer EAA witness poly p that will sometimes jam a cartridge on ejection and will fail to fire interm. I have tried winchester ammo, sellior belliot, and other cheap ammo. All acts with the same concerns. I really want the gun to be my concealed carry gun but with fail to fire occuring every 30 rounds or less I don't trust it. The hammer will drop normally but nothing, leaves a small mark on the shell and will usually fire the next time I pull the hammer back. Please help, almost ready to get rid of the thing.

Didja clean it 'fore ya shot it? Are ya feedin' it hollowpoints as well as everything else? Do you know the term, "limp-wristing"? Are you holding the same every time? How many rounds have you put through it?
These and other questions await.

I have cleaned several times, after I take to the range everytime. The gun has had both winchester hollow points and several other brands of normal style fmj ammo, I don't believe my holding style is the cause since the concern doesn't happen when I shoot other pistols. I will try adjusting however. What about polishing the ramp or stretching the recoil spring slightly? Please HELP I love the gun otherwise. 0 -
PLEASE don't start stretching springs or Dremeling away anything yet; neither would cause it to fail to eject. When you say that it fails to eject; do you describe a "smokestack" condition, where the ejected shell gets caught in the ejection port, or do you mean that the extractor hasn't gotten under the rim to pull the case free of the barrel?
Also- are you manually cocking the hammer just before it fails to fire, or are you allowing the previous shot to move the slide back to cock it?
AND- I assume it's in 9mm, does the bottom of the slide have a nice shiny brass-colored stripe down the middle of it where it rides the top of the magazine?
Another possibility is that when you cleaned it, you may have left some crap(technical gunsmithing term) underneath the extractor, if there's anything collecting under there; it may interfere with positive extraction.
If it's a smokestack condition; you could have several causes:
weak extractor spring
filthy chamber (from dirty ammo, unburned powder, etc.)
high subsequent round in mag (mag tuning needed, or not, since most other rounds feed OK)
too strong a recoil spring-closes slide before fully ejecting case (can be traced by dents on ejected case necks/bases)
The failure to fire could be from not having the hammer at full cock from a previous round, or possibly some crap in the chamber that prevents the round from chambering fully, and the hammer blow only seats the case in the chamber and leaves a small indent on the primer.
Hmmmm, do you use Q-tips to clean your chamber, or do you use bronze bristle jags? Also, what solvent do you use?

As Gunnut has pointed out, more specific details on the nature of your problems are needed. However, im going to make a guess based on the TWO problems your having as being symptoms of the SAME cause. Sometimes the manufacturer will produce a barrel with the Chamber slightly small in diamater, which will cause; 1- the shell to not seat quite all the way in. As Gunnut suggested the firing pin then PUSHES the shell slightly instead of sharply impacting the Primer. Evidence of this is what you described. 2- because the chamber binds slightly, it will increase the resistance to extraction, especially after several rounds have been fired and chamber gets "dirty". Because of slight manufacturing variations in each round made it also does'nt happen on a predictable basis, but is regular (20-30 rounds you said). Even if this is not Exactly the cause, i'm betting its related to the Chamber dimensions/shape. Having a gunsmith check and Hone the chamber out slightly might be whats required. Just a guess though, good luck. By the way, what is the caliber? 0 -
The gun is a .45, the fail to eject is "smoke stack style" round stuck half way out the ejection port. The fail ti fire may be related to not seating fully in chamber since the dent is small and sometimes will occur even after I pull the hammer back manually and pull the trigger. may even take 3 releases of the hammer to get the shell to fire. How much would it cost to have a gunsmith perform the chamber check and hone? Hey thanks guys for the free help. Please responds if this helps narrow down the likely cause. 0 -
.45; it figures. OK, here's what you gotta do:
1) Check under the extractor for the spring-is it there? Does it move freely back/forth? Is there anything that might impede its' movement?
If so, use canned air to blow it out or (if you're handy) drive out the roll pin holding the extractor in (don't be afraid to look at the manual)from the bottom of the slide (get ready to grab the spring, extractor, and anything else that flies out). Clean the recess thoroughly & reinstall.
2) Look closely at the tip of the extractor that grabs the case, use a magnifying glass if you have to-Does it have a burr, jagged tip, missing piece or look as though the finish has globbed up under there?
If so, get the extractor out and GENTLY remove the malignancy with a hand file of appropriate size-DO NOT REMOVE ANY MORE METAL THAN YOU absolutely HAVE TO !
3) Check your recoil spring and guide-burr free and shiny smooth?
4)When you clean the gun, do you remove the barrel and carefully clean the chamber every time?
5) Make sure the gun is apart, and take a loaded round of your choosing (after shooting a coupla dozen rounds or till it jams) and holding the barrel pointing down in your right hand, drop the loaded round into the barrel with your left hand-Did it go all the way in?
Is the chamber so full of unburned powder flakes that you can lightly push on the round and feel it bottom out?
If so; we'ved solved both problems and cost some poor local gunsmith about $45 if he's honest, and more if not.
Try these before you do anything; you need to know your gun to shoot it well.
