Cleaning Airweights

[SAWBONES]

IOSSO bore cleaner (get it from Brownells) with a nylon brush works very well for cleaning Airweight cylinder faces, and doesn't take off the finish. Works for cleaning the 340PD cylinder coating (whatever it is) too.

I had a 638 Airweight. The finish became badly damaged, I sent it to S&W and they replaced it at no cost (new gun entirely). I got a call from S&W, they asked me not to use Hoppe #9. Hoppe Elite or M Pro 7 work fine. Now I only use Hoppe #9 on vintage blued handguns and long guns.

Im glad they took care of you...I hope they put that info in the manuals! !
