There are many "flavors" of 30 sk's. I got a da/sa/decocker/ambit safety/nite sights first and HATED it.
The DA was long and heavy amd I dont like the 1911 style of cocked and locked.
Got a Lite LEM version, no safety/no decocker, much better to shoot.
Try them out first to see what meets your needs.
Great Gun, built like a swiss watch/tank!
But accuracy from both of them beyond about 5-7 yards was horrible in my hands. My 5" Sig 9MM's are much better shooters, but the 30SK is a great close range CCW weapon.
I couldn't get good groups at longer ranges from my 9MM Shield either.
My Shield in .45 is a much more accurate CCW in my hands, and despite fewer rounds, fits my needs much better.
