Just this year purchased PT740 Slim. Have S&W 9VE for a bit. Keep both at condition 1 24/7. Have purchased extra magazines for both. Mark first round going into the mag, then load to max. Do same with second magazine, and that one goes to near by stash spot. (NO WORRY. No KIDS.) Always have one magazine empty next to box of factory hollow points. When inserted magazines goes through all rounds, empty that mag and load empty one, inserting stash magazine into pistol for next go around. Rotating magazines, two to three time a month. When changing magazines, will always spend 10-20 minutes of dry firing with both pistols.
