You may want to look into a Heckler & Koch (German) pistol. I did a LOT of research, and it is an incredibly well engineered pistol.
Here's my HK P2000:
It's a DA/SA with the decocker on the rear next to the hammer. 11# pull on the first shot, 4# on the remaining 12 rounds. It comes with four adjustable backstraps to custom fit the grip to the individual.
It's Terrific carry as well as home defense gun.
I’ve had the 9mm version for years now. And the design has been around since before 1995, when it was th HS95 and adopted by the Croatian military and police. That become the HS2000 and later the XD. So it it’s basic design has about 12 years under its belt.
Except on the caliber ;)
