Dear Officer Friendly:

Hell no.
Sincerely, etc.
Gun distributors are stuck between a rock and a hard place. Maryland law states that gun buyers should not have to wait more than seven days to receive a firearm, while Maryland police are requesting as much as 10 weeks to process the background checks.


From James, what a 8mm rifle bullet does to a S&W barrel.


(some bits added to this part)
On the CLP tryout, it did a nice job of cleaning out the barrel & chambers; not the most strenuous test, thanks to modern ammunition most anythings does on .22s.
Speaking of which, if you've never seen one, here's a mostly-disassembled S&W K-frame revolver

Here you see the frame & barrel, sideplate, trigger unit, hammer unit, cylinder latch & thumbpiece, mainspring, trigger rebound slide & spring, hammer block, cylinder crane and cylinder unit.

'Mostly-disassembled' because
Did not remove the firing pin & spring from the frame
Did not remove the ejector rod/extractor assembly from the cylinder
Did not disassemble the trigger and hammer units
Did not remove the cylinder lock from the frame.
The trigger and hammer units, you only fully disassemble if they actually REQUIRE it for work/repair.  The hammer, for instance has
Hammer
Mainspring stirrup and pin
Sear and pin and spring
In this case the firing pin is mounted in the frame; in a lot of them it's pinned into the hammer and properly referred to as the hammer nose.  In any case, that's a number of small parts I leave the hell alone unless they REQUIRE something be done.  Since they're all working, if it was really nasty I'd flush them out with brake cleaner and a brush, then lube.

The trigger group has the trigger and five other parts, including a spring; and I'm not messing with removing them unless actually needed.

The units were cleaned out as needed, and everything wiped clean with the CLP and left overnight*.  Just wiped them down, added a dab of CLP where needed and reassembled.  Feels nice & smooth, as it should.  I'll do some dry-fire practice, and the range next time I can, and see if it stays that way.

This pistol wasn't real dirty, but it was the dirtiest available; I've always been pretty much a 'if you shoot it, clean it' sort, so nothing gets very bad before it gets taken care of.  I need to let something go a while and get seriously dirty, then try this stuff on it.


*because I ran out of time, not due to horrible/nasty/'let it soak' condition
