do not know if my sig applies but I do have the mosquito. I purchased and took it to the range the next weekend. I did not clean it before I took it to the range. no rpoblems. my xd didn't have the oil on it and I didn't clean it before it went to the range. my taurus had the oil on it. they wiped it down before I left with it and I went to the range the next weekend. have not had any problems at all with either of the 3. I use hoppes #9 products to clean and rem oil to lube. nothing special but the products work and keep my pistols working. hope this helps.
