I have 3 45's, the Glock 30 S, is hard to beat as far as being a 20 oz gun, with 11 rounds ready to go, and a 13 round reload. There comes a point in a gun carry owners life, where if something worked for you, then why keep buying guns? I went through that phase for most of the 50 years I have been using a handgun. Once you find a 9mm and a 45, "or whatever caliber you carry", and it delivers everything possible that you would or could need in a situation where a gun is needed, then the idea of continually searching for something better , is just an obsession. I totally believe in upgrading, like from a 30 to a 30 "S". But other than that, what exactly does one expect from a pocket sized pistol that any of the popular models don't already have or do?
It should be a gun that you can carry easily and that has the power to stop a threat, other than that unless you compete, seriously, what else do you want from a carry gun.
Collecting is another story, or hunting with a handgun, but for carry, you want a good reliable gun that works all the time. All the rest is manufactured marketing gibberish. The odds are that maybe a few people out of thousands here will ever have to actually shoot someone, and the last thing on their mind will be trigger creep or reset distance, it will be over 1,2,3, and hopefully the gun functioned as designed to function, and you did your part in stopping the threat. The last thing on your mind will be the which gun was better for what, or why someone sold their gun. I have an XDS, and find it to be a very reliable small easily concealable handgun, I carry it often.
