    Can I use the double-recoil spring assembly from a Gen4 G17 in my Gen3 G17?

    No problem. The cutout on the underside of the slide is bigger on the Gen 4 to acomodate the front circular plate, which is bigger than the ones in the Gen 3's.

    I do believe that you could take a Gen 4 upper and put it on a Gen 3 frame, however.

    Waiting to see if someone will try to modify a gen3 slide to take the gen4 spring.

    Is there an aftermarket recoil spring assembly for the Gen3 G17 that is of a similar design to the Gen4 recoil spring?

    Give it time. In theory, it shouldn't be too difficult. One just has to have the right machining tools I guess.

    No doubt some 'tard will try to, then blame the malfunction on Glock.

    Besides modding the Slide, you'd have to mod the frame cut out, and the recoil cutout rest on the barrel.

    What he said. The machine work would cost quite a bit.

    There is a member here that has over 50,000 rounds fired from a G19,
    all springs are stock. None have been replaced, that's good enough for me.

    Given that the new recoil spring is supposed to address some of the "snappiness" of the .40 S&W, is there soe sort of standard type spring that one can install, perhaps a progressive type spring, that will give the same result?

    Someone had posted something like that in a thread about g30 recoil. I can't find the thread again, but it was called mechanical recoil recuction if i recall correctly. It consisted of three different springs and replaced standard gen3 guide rod assemblys. I believe the company's name started with a "D"

    ..if you want to replace the guide rod and spring...check out SPRINCO, Lone Wolf or Lightning strike...

    if you really want the double recoil systems for your Gen3's,2,1...then I've seen this link posted here on the forum:

    Anyone have experience with this product. Your thoughts? I'm hesitant to changeto a steel guide rod, and most other non-factory mods.

    IIRC, the recoil spring on the G-22 is the same as the G-17. Given that the .40 S&W offers a more "authoritative" recoil implulse, could one use a heavier recoil spring. What is the weight of the OEM spring. Would adding a spring of say 1-2 lb. more weight have an appreciable effect of felt recoil. Would such a change in an otherwise stock pistol affect reliability of function? Sincerely. Brucev.

    The new recoil assembly was designed for the G22 and used in the G17 also. It is plenty strong enough. The spring is of a heavier weight than the G3 assembly.

    Thank you for the information. It has been suggested to me that installing a heavier recoil spring in my G-22 would afford more reliable function as well as some degree of protection of the frame from the cumulative consequences of recoil.

    I have not found the G-22 to produce anything remotely close to objectionable recoil with any load using the OEM spring. However my experience with .40 pistols is not extensive. I have far more experience with 9mm and .45 ACP pistols. I have some experience varying spring weights in 1911 pistols to permit reliable function with a variety of loads. Since to this point I have only fired factory standard .40 S&W ammo in my G-22 and since this pistol has now reached the 1,500 rd. mark, I thought it might be wise to listen and consider replacing the recoil spring with a heavier unit. Again, thank you for the information.

    I have used them with stellar results.

    Going with a heavier bullet can also reduce the feel of the recoil. Keep your springs fresh no matter what.
