37 slide on a 17 frame?

    I have a single pin G17 frame that is customized and would like to know if the G37 slide would fit. Is the 22000 psi/cup of the gap round too much for the G17 frame? The 9mm psi/cup is much higher so I am keeping my fingers crossed.
    TIA, Bob

    I have actually wondered about the same. I think what you are saying is that you have a two pin second Generation frame, not one of the newer 3 pin frames.

    Here is my take on it: The reason they changed to the 3 pin design was that Glock supposedly had some problems with the locking block when they introduced the .40 caliber Glock 22. They then went to the 3 pin design ( two pins on the locking block) for the Glock 22 and a short time later in order to standardize they discontinued the 2 pin design altogether. So all current Gocks have the "new" 3 pin design.

    I would compare the Gap more with the .40 than the 9 mm and although in all likelyhood it would be fine I doubt that anybody can say for sure how long term the 37 top would hold up on the 17 2 pin locking block.

    But if anybody has done it, I would love to know as well.

    I would not attempt this....

    Bound to be differences in frames locking block dimensions, etc., in addition to the older frame possibly lacking rigidity....

    Yea, I would think any difference would be in the locking block. I have a fram that uses the shorter G19 mags.

    The G17, 22, 31 and the G37 share the same frame. HOWEVER, since it is different generations, it will not work safely.

    IF you had a 3rg gen G17 frame, all you need to change is the Ejector, Trigger Bar, and Slide release, then slide the upper on it and pull the trigger..

    But the Gen 3 G17 frame must, MUST, MUST have a locking block pin (3rd pin). Gen 1 and Gen 2 frames are out of the question. GAP owners are the smartest of all Glock owners. Don't do anything stupid.
