I did a 3 day canoe trip this week and wiped out in some rapids. My USPc was completely submerged for several minutes. Once I recovered, I unpacked all my gear and saw that my dry sack containing the gun had failed. In my 36 years, I've never managed to completely submerge a firearm for any reason.



I've noticed already that the spring behind the mag release has some rust on it. Do I need to have someone take it apart for a better cleaning than I'm capable of?

Either give it an oil bath or heat it well with a hair dryer to completely dry it out, then oil well.

As said by the previous post it could probably be taken care of with an oil submersion, but a trip to a gunsmith couldnt hurt if your worried.

Thanks guys, I oiled it very heavily and then used a can of compressed air to spray the oil out of the crevices. I gave it a good cleaning and everything I can see appears ok, however, strangely, the decock is much harder to push down than it was before.



I bought this gun last year and it's had maybe 200 rounds through it...I guess I may pay someone to take it apart completely for an inspection.

You may have some debris inside the decocker mechanism still if it is hard to operate. You might try light tapping on a table in various angles to see if it will dislodge.

Shooting it will dry it out.

Couple cans of wd-40 and then lube.

I'd take it apart if it was salt water.

It isn't rocket science to disassemble,but shouldn't be necessary.
