Dual recoil springs on Glocks

[potmetal]

I just saw a show that featured the new Gen4 Glocks. I think it was a re-run, but it brought up an interesting point.
The Glock rep was showing off a new model 22 and said that the new dual recoil spring system, as opposed to the old single recoil spring system, reduces wear on the spring, and reduces felt recoil.
Any Glock gen4 owners agree with the felt recoil claim? If that's true, why don't more guns use a dual system?
The only Glock I've owned is a 2nd generation model 22, so I'm kinda behind the times.

The dual effort on the G-22 .40s has been a success. In my estimation it really doesn't do much to recoil perceptions, though it significantly reduces wear to the mechanism, and allows the slide to cycle properly with a light attached to the rail(the primary reason they ventured into a dual recoil apparatus in the first place).

The 9mm 17s are an entirely different matter, with apparently three seperate redesigns already on the books to the G-17 dual spring due to numerous faiures to feed & eject, they clearly screwed up the functional reliability of what is arguablly the finest combat 9mm pistol ever produced!

The only legitimate claim is that it increases spring life. Everything else is BS.

I can't speak for the .40, but I fire the Gen3 and Gen4 G19, regularly. The Gen4 recoil is substantially softer and has less muzzle flip in my hands. Of course, in smaller, weaker hands, the Gen4 may fail to cycle all the way.

It's common knowledge that changing recoil spring weight can affect felt recoil. Many owners of PA63's and P64's buy heavier recoil springs for this reason. The Gen4 spring is much heavier than the stock spring. If the Gen3 is 17 pounds, it feels to me like the Gen4 is in the neighborhood of 24-26 lbs, but i haven't measured it.

Also, the dual recoil spring has more mass than the gen3 plastic guide rod.

Had a Gen 4 G17 and had the opportunity to fire it side by side with a Gen 3. The Gen 4 had noticebly less recoil, especially on the stiffer loads.
