I believe the best way to carry the PPK is with the safety off, Red Dot showing, That way I'm ready with my First round being DA & consequint rounds being SA of course..
I don't think you could accidently pull the trigger DA on a PPK..
I would recomend Applying the safety first before stripping the first round from the magazine, This will safely charge the barrel & decock as well, Then either refill the magazine or just switch the safety off & your ready to go..
I also find that the safety is in the way of racking the slide a bit, But with it applied there's more of the cocking serations exposed in front of the lever..
I don't think you'll find many people carryin that leave the safety on with a round in the chamber.. I could be Wrong?
Others will chime in that have more time under thier belts, as I've only had a PPK/S for four weeks as of yesterday..
Hopefully I'll make it to the range today, It's supposed to warm up to 55 degrees today. & a Buddy of mine bought a Bulgarian SLR-101S last week for $225 cash at the GunShow & we haven't tested it yet.. He has four AK-47s.. An Addict For Sure!!
Enjoy the PPK & Stay Safe!!
