Do you secretly feel maybe just a little better armed with the 10mm?

A G20 rides in the trunk of my unmarked police car loaded with two mags of Hornady 155 grain XTP.

We carry 9mm as an issued duty round. But in a SHTF situation the G20 gets the nod.

Secretly?

What's that huge bulge in your pants or are you glad to see me?

All depends on the situation. Yeah one deranged whacko, 10mm plenty firepower. Riot, unknown quantity of BG's trying to break into my house, I'm breaking out the AK with the 30 round mags.

I don't know a lot about physics but a bigger bullet at a higher velocity has got to be better. Right now I carry 10mm exclusively and before that 45acp. I always chose stopping power over capacity but with my 10mm Glocks I've got both.

I think given the penetration necessities of stopping a bad guy and that 9,40, 45 all get deep enough that the extra recoil is not really doing that much.  In a hunting situation you are shooting from say 25-50yards where the velocity helps and also you get much more time to take a shot at a target that doesnt know he is facing armed opposition.

With regard to the OP...
Absolutely yes and no question about it IMHO.  The all around flexibility of the caliber to perform well in almost any situation in which a semi-auto handgun could reasonably excel makes it a great choice.  Nothing magic, just all around strong performer in many, many areas.

With respect to recoil concerns...my view is it's subjective perception of the individual shooter; heavily influenced by many factors not the least of which is training.  No not saying hot as hell 10mm as docile to shoot as 22LR for most shooters.  However, Jerry Miculek shoots a 50 cal desert eagle faster than I shoot a 22LR.  For that matter he shoots a 50 cal Barrett free hand faster than I can shoot same 22LR too.

 Well ... How about I feel an extra level of confidence with " more than aaverage powerful " round ? This also includes full power .357Mag , 9mm+P+ , .45acp & O+P .For backwoods include Ruger level .45LC .
