Got a fairly new 41 that would jam on first shot after cleaning the barrel. Did it like clockwork. So next time i cleaned it I used a qtip with a little Imperil die sizing wax in the chamber. Hasnt jammed again. Just saying.....
My 41 which has been very reliable occasionally jams on the first shot after I have cleaned it, after that no issues. Not sure of the cause, since I know it does that I just shoot a shot at the range and if it jams I clear it and move on. On that note I used to clean my 41 after each trip to the range now I wait until I have put over 1000 rounds through it and I have no issues what so ever. My go to ammo is CCI SV.
