    Depends on how 'micro" you want to be in your terms definitions. FTF, FTEj, Dud, FTEx are the 4 Macro categories but each can have variations. Stovepipe for example is a form of Failure to Eject. Squib is technically a "Dud" but not a complete Dud. There are many others but the bottom line is that if you're into splitting hairs the list can grow rather long.

If the website is correct, then most people wrongly many malfunctions to the terms "misfire" or "hangfire," even when the malfunction has nothing to do with the proper operation of the cartridge itself.

    For example, I've experienced misfeeds having to do with the ramp being a little too steep and the lip of the hollowpoint being a little too sharp. But it's not a hang fire, much less a misfire or squib load.

    What other malfunctions have you experienced? Proper names for them, if you would, please.
    Defintion of a squib load, from Range365.com
    A squib happens when a cartridge doesn't have a sufficient propellant load to push the bullet out of the barrel. This can also occur if the propellant doesn't fully ignite. The bullet then becomes lodged in the chamber or barrel.
    I was not sure if a squib load was defined and understood; so that is a fine definition of one. If you hear a pop instead of a boom, you may have a squib, and the bullet may be jammed into the barrel. So on the next trigger pull, you will fire a bullet into the jammed bullet, in the barrel.
    That can ruin the barrel. So, if you hear only the pop, and not boom, check your barrel. Run a cleaning rod through it, and if there is a bullet in there, you will know it.

    Here's a question: In semi-autos, does a squib load with a bullet stuck in the barrel even impart enough energy to cycle the action? Yes, no? Never? Maybe? Always?

    This might be more interesting if the list included what was done to overcome the failure. I have had the failure to load properly for two reasons. One was from too heavy of a recoil spring and that caused the cartridge to be trapped half way out while being extracted and then the next round couldn't load. The other cause was that the feed ramp needed polishing and then polished again until it had a glass shine. My only problem with extraction aside from too heavy of a recoil spring came from the tip of the extractor having a chip break off right where it is supposed to catch the cartridge. I have a couple of other guns that I don't carry every day that I need to look at and figure out why they don't perform reliably all the time. I always want to shoot the guns that perform the best and forget about the ones that have problems.

    You answered your own question. Depends on the squib as not all squibs are equal to every other squib. Yes it can. No some dont.
    Those are my principles, and if you don't like them.....well, I have others.

    I attributed this to the recoil spring, and made a conscious effort to tighten up on the grip ( Iím a very relaxed shooter), and after I did that, the problem stopped.

    Now, several hundred rounds later, the issue is completely resolved and it runs smooth as a sewing machine.

    Unless it is a extractor issue, or something really out of whack like a bad feed ramp angle, I think spring timing is the culprit just about every time.
    Mag springs included.

    The BoB issue with regards to the newer super duper slickery slick lubes was pointed out to me by a custom 1911 smith. Overlubing could also cause this problem, he said.

    Neither is the poster. (Sorry, that was just too irresistible to pass up! I'll make it up with a Christmas card.)

    My firearm "malfunctions" are so few and far between I don't give it a second thought. The only persistent malfunctions I've experienced were with my Glock 30 (Yikes!) when trying to hand load 200-grain SWCs that just would not work and the recent experience with my AR-6mm Mongoose that turned out to be an incompatible upper and lower. Different lower resolved its problems.

    I have more vehicle malfunctions than I do gun malfunctions, and like my guns, I just get it fixed and carry on. I think some get too wrapped around the axle about gun problems. Everything breaks, most things are easily fixed, and only true lemons should be a concern.

    All firearms have the same cycle of operation, any interruption of that cycle can cause a malfunction. Feed, fire, extract, eject. There are multiple causes for malfunctions but they all fall into those four categories.

    It sounds unlikely, since the powder charge does not have enough oomph to get the bullet out of the barrel.

    In a class today with instructor, 7 darned good shooters and me. All but one are shooting 9mm, the other is a 45. Mine is vintage and I think all the rest may be less than a year old. Weíre all shooting same mfr semiautomatic handguns (it doesnít matter what brand, this isnít about Glock Perfection ;-) Weíre all shooting at same cadence, sometimes slow and sometimes fast. Today we collectively shot close to 3,200 rounds without a single handgun failure. No failure by eject or stovepipe, failure to feed, or double feed. Sort of supports G26 Ravenís angst over a new and expensive handgun miserably failing his expectations.

    When I shoot matches a lot of folks shoot reloads. Do we have more failures? You bet! Hard to tell right away whether itís the machine or the ammo, but Iíd be willing to bet reloads are involved. We often have 25 to 35 shooters each throwing 110 rounds down range, so the round count isnít much different from todayís class where 8 of us each shot 400 rounds. But the match activity is admittedly very different because in the matches weíre likely to shoot sometimes without a good a stance or good arm position.

    FWIW, The Class requires factory new ammo, and the range requires brass casings and jacketed bullets.
