Me, personally, no Glocks. I'd go DA decocker. I like my Ruger P90, perfect, love it, just wish I could get one in 10mm. The 10mm is MUCH more powerful than any other reasonable, available in a reasonably sized carry gun, auto pistol cartridge. It's a .357 magnum with a bigger bullet, how could you miss with that? Ruger will likely never make the P90 in 10, but if they decide to, I'll be in front of the line waiting on mine.
If all you want is self defense with the gun, the .45 is really hard to beat. I see the 10 as an outdoor caliber for autoloaders and it's a danged fine self defense caliber loaded to +P .45 levels (light for a 10, say a 180 grain to about 1100 fps), too, sorta like a .357 mag in an autoloader or more like a 4" .41 mag, but in an autoloader because to reach 10mm levels, the .357 needs a 6" plus barrel.
JMHO, of course.
