A few recent range trips have seen this Les Baer Concept VI digest around 600 or so rounds with no formal cleaning. Normally I’m a stickler about cleaning guns ASAP after a range session - I decided to let this one run a bit for a change. If Uncle Les tells us to run a new one 500 rounds before cleaning, an older one like this ought to be just fine...and it was. Around the 200- and 400-round marks, I applied a few drops of Militec-1 to the slide rails and smeared a drop around the exposed barrel with the slide locked back. After each session, I wiped-off the external surfaces only. No failures / stoppages along the way - a happy yet not surprising outcome! The gun “felt” as smooth at the end of this multi-trip run as it did at the start. Posed here atop or near a fresh set of less-than-premium-grade store-brand paper plates are some of the dirty parts before cleaning commenced - this 1911 is now all shiny once again!
