Wet - as many on this site have noted, lube the magazine tube, gas piston system with Break Free CLP. Clean up with a paper towel about every 500 to 800 shots and re-lube. You will like this method. Best Regards, Ed
You all forgot to mention CLP as being able to improve your sex life. It's the new substitute for Viagra!
Really now, it work OK, as both a cleaner and a lube. That's pretty much all you can say. I have used it for years and buy it in the gallon size. Works on other things besides guns. I don't soak my guns in it, but I do leave a little on the 1100. I won't say "WET", maybe lighty damp? Too much and it collects dirt quite badly and it seems to spread everywhere.
Brownell's sells it, but it's more than $92 and is overpriced like everything else they sell at retail. I bought my last one from a local vendor at a gun show and bought one from Midway-USA a couple of years ago, but they no longer carry it in the gallon size. Natchez has it for about $56 and that is probably where I'll get my next one, unless I can beat up that vendor at the gun show again. I paid him $45 total, out the door. See the link above for Natchez. Midsouth shooter's supply is only a couple of dollars more.
Go to one of these URLs as an alternate, since they are also fairly reasonable:
If you are just shooting singles, it probably won't make much difference if you shoot it wet or dry. But if you are shooting doubles, it just might make a difference.
Of course, if you take the gun apart and clean it every 75 to 100 rounds, it won't make much difference either way, but if you want to shoot 300 to 500 rounds between cleanings, then I would recommend shooting it WET.
Also, don't forget to clean/lubricate the recoil spring and magazine spring about every 3,000 rounds. Likewise, I would replace the recoil spring and magazine spring about every 8,000 rounds. If the magazine spring gets weak, the second round will be left lying on the carrier with the bolt locked open. If the recoil spring gets weak, the gun will have cycling problems and will suffer added abuse and parts breakage.
