    The rail portion of this receiver is bent slightly upwards. I think I’ll try to warm that section with a heat gun and stick some shims in there, allowing it to cool with the shims in place. Not sure if this type of plastic can be reformed like that but I’ve no idea what else to try.

    Anybody else had this on their Glock? Doesn’t seem to affect the accuracy so maybe I should just leave it alone but it’s one of those things...

    A lot of Glocks exhibit this. It doesn't affect function.

    I doubt melting it would help matters. If you have ever seen super slo-mo video of a Glock firing the front end looks like a diving board bouncing.

    Yeah it doesn't really affect the accuracy. Or if it does, imperceptibly so. Guess I didn't know if it was normal or not but it sounds like it is.

    Ive seen others bitch about it. Heres one, and he "fixes" it.....

    https://www.everydaynodaysoff.com/2012/07/02/fixing-the-glock-pig-nose/

    ETA: This was in the comments and may be a safer thing to try first....

    "If the “Pig-Nose” really bothers you- field strip while setting to boil a small pan of water- when water has come to a boil, dip and hold the dust-cover portion of the frame under the boiling water for no more than a minute- immediately press the hot frame flat against a counter top- not too much pressure – hold there until mostly cool- Presto- no more “Pig-Nose”. Surprisingly, it will hold the now flatter shape, even after running 3 15 round mags in a row. This method is fast and carries little to no risk of damaging your frame.
    (And yeah, the “Pig-Nose bothered me)."

    Well known issue and it does bother me. I have a couple that are pig nosed. I may try the boiling water method on one and see how it goes.

    My G19 looks just like that too. I'd say they're made that way.

    Glocks aren't made to look pretty, they're made to shoot bullets.

    You want pretty, get a nickel plated revolver with pearl grips. Like a pimp in a cheap New Orleans whorehouse.

    Lol pretty is one thing but I at least want everything squared up. It doesn’t matter THAT much to me but still I don’t like it.

    yep started being called pig nose back in the older days. no need to do anything. many glocks have it. some of my glocks have it. completely harmless.

    ironically the m&p had a down turned nose in the early days.

    Hell, mine is so worn and rough looking, that would be the least of my concerns.

    Seeing my bullets from outside the gun bothers me far more than the hog nose.

    Why does that bother you?

    Too much gap between the frame and slide. Or to put it differently, the same reason the hog nose bothers you and not me. :) Just one of those things.
    Course aesthetics are not why I own Glocks.

    I always enjoy hearing some people say they don't care about aesthetics AT ALL. but then they don't buy Hi-Points or Walther PPXes based solely on looks. Or pink and baby-blue Glocks. Or guns in baby-poop brown. Or bright yellow trucks. Or whatever they don't like. To me Glocks have a well-balanced purposeful, functional, utilitarian look about them but there ARE visual design elements that take a lot of thinking power at Glock, Inc.

    I personally don't like the look of the silver slide variants. But I generally am biased toward black slides and silver frames.

    +1 on that

    I like the aesthetics of my glock; it’s functional. But when part of it is warped I don’t like that. Much the same as if the bumper on my truck or car was cracked I wouldn’t like that. Sure, it’s a work truck but I still take pride in keeping it looking good.

    Thankfully none of my Glocks have pignose. It would bother me greatly. The topic of pignose brings out some pretty harsh responses from those that don't think it's a big deal. They WILL question your manhood and your mom's purity if you simply like a gun's frame to not be warped.

    Tried the boiling water for one minute thing. Helped a bit. I may do it again.

    The "pig nose" problem is so Obsessive Compulsive Behavior. As long as the pistol functions, I would advise not messing with it, especially not heating up thermoplastic plastics and bending them around to make them straight. I have to be honest, I am not an expert on heat and thermoplastic deterioration. But I did find material on Maximum Continuous Service Temperatures, which makes claims that at a certain temperatures, thermoplastics material properties deteriorate. And, do you really know which thermoplastic is used in the frame? And due to my own ignorance on this, I would advise not heating up your frame to fix what is a cosmetic issue.

    More on this:

    Turning Up the Heat: Considerations for High Temperature Applications


    Thermal degradation: How long will the material maintain its strength?Thermoplastics exposed to elevated temperatures for long periods of time will generally become brittle and lose both mechanical strength and tough-ness. This process will occur more slowly at moderate temperatures and more quickly as the operating temper-ature for a material is increased. This behavior is evident in older cooking appliances which often have degraded and chipped plastic handles. The rate of degradation will vary from material to material and the degradation rate for a particular polymer can be repre-sented on a graph as shown in figure 2. A 50 percent loss of initial tensile strength is used as a standard to show the degradation rate of a material at various temperatures.

    I think there is a big difference between not wanting the frame of your pistol to be warped and...

    https://www.nimh.nih.gov/health/topics/obsessive-compulsive-disorder-ocd/index.shtml

    Obsessive-Compulsive Disorder
    Overview
    Obsessive-Compulsive Disorder (OCD) is a common, chronic, and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and/or behaviors (compulsions) that he or she feels the urge to repeat over and over.


    But, I do give you props for creativity in insults; never been accused of having a clinical mental disorder before for not wanting a frame to be warped.

    a Glock left in a car in Phoenix in August is in big trouble then! :rofl:
    I just dipped the nose in the water and if there’s any thermal degradation I’ll eat my hat.


    by the way I mean this light heartedly: Slamfire advising against obsessive behavior is like Rosie O’Donnell giving diet advice. :D

    Heat alone, until it becomes extreme (over 400 degrees F), isn't likely to damage a Glock frame. Hot cars? No problem. If the frame is cool enough to pick up without burning yourself, it's also cool enough to shoot. If the frame is much over 250 degrees, let it cool down before shooting the gun. If it's much over 400F, you probably need a new Glock.

    However, heat and water together are a bad idea. The Glock frame material is hydrolytically attacked by water over 120 degrees.

    So my suggestion is no cleaning Glocks using dishwashers and no frame reshaping using boiling water. The gun's not going to turn to mush the first time you do it, but the practice will compromise the material properties of the frame--it's not doing the gun any favors even if you can't see immediate degradation

    My OD Gen3 G17 has the so-called “pignose”.
    It doesn’t bother me at all, since I usually only see my G17 from the rear, looking down the sights.
