    I ordered these about a month ago and got them yesterday. I asked for the latest versions for my recessed slide (counter bored) Gen4 pistols. I have had no malfunctions of any kind with the original RSAs that came with the pistols, but I did have reservations about the way they were made. I felt that even though the slides were recessed that the front of the outer coil could work its way out of the front of the slide. I also felt and observed (on another forum member's G17) that the collar that separates the inner and outer springs could get hung up on the front coil of the outer spring preventing the slide from going back.

    Left to right:

    G19 0-4 (original), G19 0-4-3, G17 0-2 (original), G17 0-2-4, G21 0-7 (original), G21 0-7-2 showing the cup(?) that was added to the front of the RSAs presumably to keep the outer spring contained in the slide:

    A closeup of the cup added to the front of the new RSAs compared to one without that device added:

    Old (first picture) and new (second picture) showing the change to the front of the collar that separates the outer and inner spring presumably to keep the collar from catching on the outer spring and preventing the slide from going back all the way (I only uploaded the G21 old and new pictures because the G19 and G17 collars are made the same way now):

    I have never been hit with brass when shooting any of these pistols except for brass that bounces off the sidewall of the indoor range shooting stations, but I only shoot 124g factory ammo in my G17 & G19 and 230g factory ammo in my G21.

    If these RSAs work as reliably as the original RSAs that came with my Gen4 pistols, I will be one happy camper with my mechanically related reservations about the original RSAs behind me :)

    So the new RSA's make it more reliable?

    As additional info to the original post:

    The "G17 0-2 (original)" third from the left, is the "02" original. The original RSA in the G17 had no "02" markings and had 19-20 coils on the outer spring.

    For what it is worth, the one in the picture above actually has the "02" markings. The one that came in my non-recessed Gen4 G17 had no markings.

    Good info, but this post will need updating soon. A new version of the RSA is released about every month and Glock is due for another one anytime now.

    Is the 0-2-1 RSA still the current one for the non-counterbored (early production) Gen 4 17?

    Not sure if this is a joke but, no the latest RSA is the 02-4.

    that is correct.

    I have the 0-2-3 spring in my NEW G17, test fired 01/11, that was switched from an LE G17 test fired 06/11...

    But, hopefuly soon, I'll be getting that 0-2-4 spring that I called Glock asking for.

    I had a chance to put 50 rounds thru each pistol (G17, G19 & G21). They all operated perfectly as they has before) with no failures and consistent case ejection back and to the right - missing me by a large margin :)

    I know that 50 rounds/gun isn't much of a test, but since there were no problems before I put in the new RSAs, I don't expect any now either.

    Life is good.
