    So I’m a lazy slob when it comes to gun maintenance. That’s part of the reason I like Glocks. I carry AIWB and sweat profusely when doing yard work, hikes in humid creek bottoms, etc. My nice 5# trigger pull felt like it jumped to about 8 crunchy pounds on my primary carry G48. I’ve got no doubt it still would have gone bang, but decided it was time to break it down for some cleaning while watching Netflix. Lo and behold the striker channel was absolutely crusty and disgusting. I didn’t even try to clean the FP spring, just threw it in the spare parts jar and grabbed another. Moral of the story, don’t be lazy like me. Cool story, ammiright??

    Interesting. I've never had that. But I live out west.

    Dang... have never seen anything that bad. I live in SW Florida, didn't clean a Glock 17.4 for 4 years once (but did lube it over the crud). Just kept shooting it in many GSSF/SCSA matches. When I tore it down, it really wasn't that bad, and there was nothing out of place with my FP channel.

    That really looks like a lot of moisture got in there, and was ignored.

    Looks like hard water build up. You must sweat calcium oxide.

    It did, with a very lite touch from some 800 grit sandpaper.

    Maybe you could work as a consultant for the guys who think #5.5 is just too scary for carry.

    Glocks are so oversprung from the factory that they’ll pretty much go bang under any circumstance. Even when their are subjected to extreme neglect. Best not to overthink it.

    I will say, my same acidic, salty swear hasn’t had these effects in pre-2010 Glocks. I’ve got a G26 from the early 2000’s that is just fine when subjected to the same levels of neglect.

    Right, which is why it's no prob to shoot HST with a #4 spring. But don't say that on here. Like, what if you were in Ukraine dukin' with thugs, and had to pick up loose ammo from a snowdrift loaded with Russian primers?

    Was there actual rust on the spring and slide? Or is that just crud that comes off with a gun toothbrush and Hoppes #9? That's a lot of buildup there. Many years ago I disassembled the slide on a Gen2 19 I had (first time ever doing a slide disassembly) and the firing pin channel and firing pin was coated with this green, pudding like gunk. Pistol still worked and it cleaned right up with solvent, q-tips and a toothbrush. It was a combination of brass particles, oil and solvent that over time turned into this goo.

    If you are on Netflix, check out Tread. It's well worth the watch.

    Does this mean the omission of a channel liner from the slimmer Glocks was a bad idea?

    I'm going to pay more attention to cleaning & lubing this area in my G48. Yeah, I know you are not supposed to lube the firing pin area, but would a rub down with TW25B cause any problem, since it would not run down onto a primer & kill it? Maybe collect more dirt?

    A clean gun is a happy gun. I could never let my guns ever become this bad, ever.

    I’m hoping maybe all the corrosion came from the spring, maybe it had something funky going on. Though there was oxidation buildup even on the front of the FP cups. That makes me suspect some kinda reactivity all the way down to the breech face.

    My sweat is freakish and neglect these last two months has been 100%. The thought did cross my mind to put some lube inside the channel, but I just can’t bring myself to do it. Coincidentally I used TW25B on all the classic lube points yesterday, because it’s what I had handy.

    This pistol gets rust on the outside of the slide where the silver pvd finish wore off. If they ever go back to salt bath nitriding, even my acidic sweat won’t bother those.

    I was thinking the Silver Nitrate finish would keep the rust down . maybe I was wrong .

    Op, try out a product called fluid film. Excellent rust preventative

    I have owned the silver finish & now have the black. To make my story short, the silver held up poorly & the black is doing great.
