Aside from the arguements that spring fatigue is caused by compression cycles,

thats exactly it.

But subscribing to see what others say.

 

From what I understand from information I've gathered here and in my various physics classes the steel used in springs has no or no appreciable "creep". Meaning it isn't actually effected by being compressed or expanded so long as neither stretch or compression are taken past the steel's elastic limit. None of this is necessarily fact and should not be taken with a grain of salt.

 

It's my understanding that a spring under constant compression suffers no more wear than a spring that is completely uncompressed... it's the constant back and forth that is what will eventually wear out a spring.

 

Well, for whatever reason Gaston decided to do it the way he did it and I trust him because he knows a hell of a lot more than I do and he set the standard.

 

I think the OP has a valid point and concern. I have an XD40 and while a fine piece for sure, the sidearm that stays with me is one of my G23's. I shoot it better, gain a sight picture more quickly, and like the trigger much better. Certainly, training with the XD series can go a long way in equalizing these two fine handguns, but I just like everything about my G23 better. I would not feel at a disadvantage with my XD40, but I feel better with my G23.

 

this is an interesting thread and im glad you brought it up........

ive owned glock, XD and MP.....and have never felt comfortable with all three with their striker-system......

on the MP, the sear looks like a cheap piece of metal that the striker could just slide off of very easy....

ive never had an accidental discharge with any of them, but it is un-nerving...

thats why i like autos with hammers like Sig......

nothing wrong with any of those guns at all, just feel better with a Sig

 

I've long considered the fully "cocked" striker of the XD a negative relative to part/weapon fatigue compared to the less "cocked" striker of the Glock. My thoughts are greater fatigue to the striker spring (due to constant full compression when chambered) and greater stress on the striker release components.

Aside from the arguements that spring fatigue is caused by compression cycles

I've got XD's and Glocks. I like them both and keep both loaded.

I didn't know about the XD being fully cocked all the time. :shocked:

I guess I can shoot the XD a couple of times a year and see if the primer hits look good; if they start to look weak replace the striker spring. :worried: :nailbiting:

:headscratch: Lots of people carry the 1911 model 45 "cocked and locked" which keeps the mainspring fully compressed, I don't know if they cock & uncock them every day or just leave them cocked, but it being fully compressed doesn't seem to cause problems that I'm aware of.

If the compression cycles theory is true then there would be no difference in the Glock or XD striker spring life cycle. I hope this theory is true so I don't have to worry about it. :supergrin:

 

To me, it's a safety issue. I'm just not comfortable with a fully cocked striker. With my Glock, I know the trigger has to be pulled before anything can happen.
I carry a G30 chambered, with full confidence that I'm safe.

 

Who is Gaston?

 

Who is Gaston?

Gaston Glock, born 1929 (age 79–80), is an Austrian engineer, and founder of firearms company Glock. The Glock "safe-action" pistol is well-regarded and has often been copied by other companies. The process of producing the Glock pistol includes the application of Tenifer, a patented metal treatment that hardens the slides.

 

With my Glock, I know the trigger has to be pulled before anything can happen.

I'm pretty sure its that way with any decent gun :whistling:

 

The XD requires that a grip safety be activated to fire.

 

The XD requires that a grip safety be activated to fire.

And if you are really anal about safeties, they make the XD45 Service with an optional thumb safety.

 

Compression cycles causing spring fatigue is not an argument - it is a fact. Constant compression on a spring will not cause it to lose it's strength. The best design for a striker fired pistol IMO are the HK P7 series pistols (PSP, P7M13, P7M10, etc.).

 

BTT for feedback from the GT hive mind...

 

I switched to the XDm 9mm for IDPA for a bit but recently decided to go back to Glock. The big reason is the division you shoot them in. I personally like the XDm trigger but I can honestly say it did not make me shoot better then what I can with a factory Glock trigger. I can also do an amazing trigger job on a Glock in minutes with drop in parts. In my opinion the XD/XDm trigger is first class and probably the nicest in the striker fired class of pistols but is not so much better to make it a must have or better then Glock, more different then better.

I hope I'm not bursting any 'safety bubbles' here, but, a few years ago, an independent laboratory tested several striker fired handguns, including a Glock, an XD, and a P99. The Glock's striker WILL fire a cartridge from the partially cocked position. Their conclusion was that the XD, Glock, P99, etc., are all equally safe. Like Kentucky_Guy, I feel just a tiny bit safer with an exposed, VISIBLE hammer, even when carrying cocked and locked. My biggest concern is when re-holstering, which is when Glock ND's seem to happen most often. There are many documented cases of clothing inadvertently entering the trigger guard, disabling the trigger safety, and pulling the trigger. There is even a term for this affliction, "Glock leg". That said, I do own nine Glocks, and have never had an ND.

 

I carry my 21 and I am totally at ease with it. Im not worried it will magically fire. The first time I carried a Glock I was worried about it for only a brief few moments.

Holstering issue aside (because that's simply a personal responsibility to do it right), please provide some linkage to the above statement.

I'm not saying this is incorrect, however, I'd like to see the reference as well.

This would be different that what is taught in the armorers class.

 

Same test, different tester, same results. I'm going to bed. Do your own research. Google is your friend.

"Springfield commissioned a study by the prestigious independent consulting firm, Tioga Engineering of Wellsboro, Pa., to compare the systems of the Glock and XD. In both designs, the firing pin block or safety is the key element, but their test showed that a primed case fired 100 percent of the time in a Glock when the striker was released from the 62 percent normal preloaded level."

If anyone has a problem with this, contact American Cop Magazine or Tioga Egineering, not me. I could have sworn the P99 was included. I may have read a different test. Also, if you don't believe it, I DON'T CARE.

Solution for XD striker spring either way hew: www.springerprecision sells "plus power" striker springs for the XD. A person could :whistling: buy a couple of them to keep on hand in the event the striker spring ever did need to be replaced.:woohoo:

The fact that the test was contracted by Springfield skews the results.

3. "Both the Springfield Armory XD and the Glock 17 will fire if the firing pin is released from the ready or carry position, unless it's intercepted by the automatic firing-pin block"

Well...duh.

So why get your boxers in a twist? Get some sleep dude!

 

Well, for whatever reason Gaston decided to do it the way he did it and I trust him because he knows a hell of a lot more than I do and he set the standard.

+1 for that.
