The mil pro's safety lever is swiped off about as easily as any other "down for bang" type (1911 and similar)
There is no "decock" feature, if you have a round in the pipe, the gun will be in the pre-cocked state, which is pretty close to single action.
I would carry in condition 1, cocked, locked, and a round in the chamber. In fact back when there was a mil pro in the household, that is how it was carried, with the addition of a good Kydex holster you'd be about as safe as it gets with any modern pistol.
If you must carry with the safety off, you'll still have to drill in swiping it down, the one we had was easy to engage and a bit harder to disengage. And if you insist on carrying with the safety lever in the "go bang" position, a rigid holster that prevents acess to the trigger AND has no possibility of allowing a snag while holstering is needed.
Just use the safety lever, is isn't too badly designed, you'll find it natural to swipe down after a few hundred repetitions during dryfire practice with your quality holster and some snap-caps.
