E-Luder & everyone:
i posted this above, but fear it was missed, so i'm posting lower, down here lol...
E-Luder:
thank you! i was clearly over-thinking the innerbarrel/outerbarrel rattle. leave it to me....
now that i am thinking of questions you may be able to help with, i have a few more for you if you don't mind.
1) are you able to VISIBLY IDENTIFY the difference between a stock and (let's just say) a GUARDER recoil or hammer spring? i ask because i have about 6 or so springs that i am unsure of the manufacturer of. some examples are below.
perhaps there is a test to see the tension? perhaps color or length (although almost all identical, i can see some SLIGHT variation, it could also be my aging eyes...)
2) have you ever found doubling up a recoil spring to be beneficial? this is simply out of curiosity.
3) have you ever fitted an aluminum BBH and consequent Piston Head from a G17 into the smaller G26 counterpart? this is something i have always pondered.
i appreciate this thread, and your efforts tremendously!

2 photos with slightly different lighting to see if there is a discernible difference in these springs........

Hi Mike,
1) are you able to VISIBLY IDENTIFY the difference between a stock and (let's just say) a GUARDER recoil or hammer spring? i ask because i have about 6 or so springs that i am unsure of the manufacturer of. some examples are below.

Recoil Springs- the only way that I am able to identify which one is stock and which is aftermarket are:
Color- the color of the stock recoil spring is usually like a... worn greyish tone.
some aftermarket manufacturers have stainless steel ones or ones coated with like black electrolyte paint to keep the tension in the spring.
Length- the stock one is usually shorter than most other springs. Guarder's for example is longer and has more coils...
Tension( or flimsiness)- the stock recoil spring can bend much easier than the latter spring.
Diameter- some aftermarket springs hug the recoil rod tighter while the stock ones usually are more loose around it.
Hammer springs- Man....I hate playing this game. 90% of the time I lose. Everytime LOL.
For the hammer springs, I usually just look for color. Usually the stock hammer spring will be black.
Other springs like Guarder springs, have like a... "worn paint" look to them.
The Guarder one that they sell separately from the recoil spring kit is advertised as "tempered steel". I'm sure you know how that looks like.
Shooter's Design springs, in contrast for example, have a dull stainless steel finish to them.
2) have you ever found doubling up a recoil spring to be beneficial? this is simply out of curiosity.
I remember when they first came out with these "Dual Recoil Springs" (DRS) back in '94 (I think), they were trying to pass it up to consumers that by having a DRS system, it reduced recoil. Many were skeptic because of the Glock 26's were able to chamber different rounds... which meant that energy outputs would be different with different types of ammunition....which meant that the recoil spring would have had to adjust to make this claim true.
Well...maybe not I guess. From a marketing perspective, if even it reduced recoil by like a fraction of what it was, then I guess you can call it true. lol. Those smart bastards. But I digress.
But many owners claimed that it hardly made any difference at all and that there were no real evidence (mathematical or practical) to support their claim.
Then they came out of a bunch of other reasons why they used the system. One was because of the length of guide rod and using a single spring set up, the spring won't have room to coil.
This lead people to believe that the recoil wasn't actually reduced (or increased) as a single spring set up would have to absorb the same amount of recoil energy as a DRS since the weight, projectile and distance of the slide's travel remained constant (or the same).
The only difference would have been is that at some point during the rear stroke, the DSR spring system would have had to gather enough resistance between the two springs to physically stop the slide and return it back to battery.
Then the Gen 4s came out and totally changed how the DRS system works. LOL.
Anyways, in airsoft terms, a "bounce back" spring is beneficiary for shortening the stroke of the slide....for whatever reason.
Shortening the stroke leads to faster chambering of BB, faster trigger reset and thus faster follow-up shots.
For a Marui Glock in particular, it's almost like installing shock buffers. For me, I use the DRS system to protect the front bolt screw from breaking....well...most of the time anyways.
It acts as a brace for when the slide comes to a stop on the rear stroke.
THe other benefit is actually to prevent the recoil springs from "over coiling" or "spinning" (I don't know how to describe it) and unscrewing the top of aftermarket guide rods. That's why some full length rods that don't use the DRS system come with those bearings at the end. lol. I don't know how it does it. But it does.
One other thing is reduced rear slide impact (I hesitate to use "recoil power") which translates to reduced FELT-recoil power at the wrists. In airsoft this really doesn't matter since...well...let's be honest here...they're toys and recoil is next to nothing compared to real guns.
The only airsoft guys that really care (based on my observations) about having this reduced felt recoil are the competitors that need fast target acquisition and
re-acquisition.
3) have you ever fitted an aluminum BBH and consequent Piston Head from a G17 into the smaller G26 counterpart? this is something i have always pondered.
Yes, A Glock 17 piston head should fit the G26.
Remember, the G26 was the father of the Marui Glocks. The Glock 17 was based on this design.
It like how the KSC Glocks were the very first iteration of the System 7...uhh...system(?). lol.
I think the only discernable difference in their piston head designs were that a G26 used the "piston cup" rather then the more modern piston head with the o-ring seal.
