    Glock .40 slide peening

    Back Story...(even though I'm sure you know what I am talking about...)

    I have had at least 4-5 separate G22's. Only two have been brand new. I like getting PD trade ins and outfitting them with new stuff...I guess.

    On the 2-3 that have seen obvious use, there are has been the ever present slide peening. As an aside, I did not have the brand new G22's long enough to experience this firsthand.

    I currently own a Gen2 3-pin G22, and I really like it. Naturally, for an almost 20yr old weapon, it has the slide peening.

    Back to the present...
    As I understand it, peening is relatively normal, and the slide can only peen so much before it can't go any further, correct?

    Is there a way (lightly filing?) to smooth out the sharpness of the peening? Is this necessary or even recommended?

    Thanks!

    Depend on the rabbit's foot if you will, but remember it didn't work for the rabbit.

    I'm no expert but from what I can determine the peening is usually prevalent in the G27 (.40) and G33 (.357 sig) because the frame was actually made to be used for 9mm (G26). The .40 and .357 causes the frame to flex and the locking block to raise up a bit peening the slide rails. I understand it will only go so far and then will have enough room to clear the rails. My G27, and both my G33's have the peening. My G26, not at all. I don't have any experience with any Glock models other than the G30 and G36 and I've not had any peening in either of these guns.

    Rough edges should be filed or chamfered to prevent possibility of cracks forming. Would it happen to the gun? Not that I've ever heard a report about.

    Well put sir....and precisely correct. The only frames Glock makes that were initially designed for the cartridge they fire are the G17 and G20. The G21 was actually an after-thought since the 10mm was supposed to be the "new round of choice for law enforcement work" back in its hay-day. All the other chamberings are off-shoots of those frames (I believe even the 45GAP is still based off the G17 frame as well.) A Glock LE dealer once expressed to me that of all the Glocks made he believed the G17, G20, and G21 would be the ones to have the most longevity and no signs of frame stress.
