For the OP, all I read was ‘I shoot the HK better’ so seems to me that’d be the choice.
Chances are though, none of us armchair keyboard shooters will be involved in a gunfight. Still, first rule and all that, so bring a gun. I’ve decided my life expectancy will be enhanced first by not doing stupid things with stupid people in stupid places (Mr. Farnham’s rules), then by getting myself in shape so I have more cardiac reserve, and lastly getting training and being proficient with my carry gun.
For walking the dog inside our gated apartment complex, situated on an island at the end of a 3 mile causeway, it’s a Ruger LCR. If I have to venture out, it’s a 10 or 12 round gun, currently either a P365 or P365XL. While sleeping its a G19 with a G17 mag; because, you know, Zombies.
