i asked the same question to my gunsmith who has been working on shotguns since the 1950's. I have a Model 1100 and a Browning Auto-5. He told me to run the Browning Auto-5 "wet" and run the Model 1100 "dry." He said running the 1100 wet would eventually cause problems with functioning because oil collects dust and debris that will clog up the gas ports. I would be interested in other opinions from long-time 1100 shooters.WOOD DUCK said:Do you recomend running it ''wet'' or ''dry'' ?
