I remember a word of advice given to me by an older gentleman: If you carry a GLOCK, only carry GLOCKs. His point was you get used to not having any external safeties to disengage, so when you carry a gun that has one you're setting yourself up for trouble. Sure enough, I was at the range today, all excited about my S&W... pull her out, pull the trigger... nothing happens. Puzzled, remember to flick the *$*$ switch to the "fire" position, and then proceed to happily put 50 rounds downrange. Not an issue with me shooting long guns, but I find with handguns as 90% of the time I shoot my GLOCK I'm used to load, rack, fire. Adding "flick safety to "off" position" really screws up my rhythm. I guess if I started a more balanced practice regime I could get used to it, but considering I only carry GLOCK, the other pistols I shoot just for fun. I hate to say this, but I also sometimes forget to engage the safety when I reload. Shoot the mag empty, pop in a new one, release the slide, resume firing. Keep forgetting the "safe the pistol" and "unsafe the pistol" steps. Thoughts/comments welcome.
