Seems like a glock
frame is durable enough to submerse in soapy water and be given a good scrub with a bottle brush, then dried.

I just cleaned (W/ #9) 4 Glocks, a S&W M&P9 and a PX4 Storm yesterday. The polymer is fine today and will be for the next few years.

The NO. 1 reason not to use Hoppe's on a pistol with a firing pin is because it can get in the firing pin channel and gum up, preventing the firing pin from moving when you want a bang.

Also, Hoppe's used to be made of effective solvents and banana oil; those effective, toxic solvents have been removed and now there's only ineffective stuff and that damned banana oil smell. It doesn't work very well.

I doubt that Hoppe's will disintegrate your G17's polymer frame, but it certainly won't help you clean it all that well compared to more modern. less-toxic alternatives like mPro 7 and SLiP products. Plus, it might gum up your weapon and cause it to fail when you need it most.

If you like the smell, ditch your Old Spice and place a dab behind each ear.

As a Glock Armorer I can say that Hoppes will not hurt the gun.

Hahahahahaha!

Awesome instructor you got there. I guess I should stop cleaning my glocks in 2 quarts of hoppes #9 and the ultrasonic cleaner.

LOL

Must be quite the smell. I used to use simple green, mainly because I'm to cheap to buy that much hoppes

Been running Glocks since the late 80's and cleaning them with Hoppe's or the occasional bottle of Shooter's Choice when I run out of Hoppe's. With 10's of 1,000's of rounds down range from them, never had an issue. Can't recall any warnings from Glock via the armorer's channels against Hoppe's either.

Just clean them like everything else. Nothing fancy.

I am a Glock armorer and do not recall being advised against using Hoppes. also, this is a bit of an unscientific test but, I used to own a Glock 31 (FS .357 sig). I ran 10,000 rounds through it and used Hoppes, and that model is a specific one ID'd at the armorers course as having some early parts wear propblems from the pressure of the round. Never had any issues, retired it (gifted it to dad). Hopefully it doesn't blow him up.

[mjmagee67]

If I am correct. They haven't used benzene in hoppes for years.

You are correct sir.

I was told the same about GunScrubber or brake cleaner (non-chlorinated). Been using it for years to blast out the crud in my Glocks, but an instructor recently told me not to use it because it weakened the plastic parts in my Glock. Since then, I've read that the plastics in Glocks is nylon-based and very resilient to chemicals.

Very curious to see the results of your tests, OP. Kudos to you for keeping an open and methodical mind.

[TheExpertish]

Been using Hoppes on my USP40 since day one, and 5k rounds later no issues. Maybe HK just makes a superior polymer.

[Gryff]

I voted Yes, but I can't speak authoritatively that it's safe. I just know that I've never seen any problems when cleaning my wife's Glocks over the past five years.

Why would you need to use Hoppe's on the frame in first place? There a plenty of mild cleaners to remove powder fowling. Hoppe's is primarily a bore solvent and that is where it should be used.

As for the guy using Shooters Choice, I would be careful about that. Shooters Choice works excellent for removing plastic wad fouling in shotgun barrels. You do the math.

As for all the Glock jockeys that sat in a room for eight hours with a bunch of cops and learned what and what not to do to their Glocks, I'm not sure how much faith I would place in their chemical engineering backgrounds. No offense intended, but Glock armorers abound and most of them I would never let touch a gun of mine. I'm one too, I wouldn't advise anything I did not know as absolute fact.

Because its convenient, and works well.
But I don't soak down the frame...dip in a toothbrush, brush the frame/internals, and wipe down with a patch, then wipe down again with a slightly oiled rag, call it a day.
