Well, a long time ago I used to buy guns that I liked. Not guns I had any particular need for nor were they even good for carry. I just bought them.
I have friends who currently have 35-45 guns! They kind of just pick them up on a whim, but none of them are what you would call "collectable", they're just guns in the house.
Over the years I've sold off and given away guns that I'm obviously not going to use and they were just taking up space on the shelf with no chance of being used for anything other that just making sure it would shoot.
With that said, I've cleaned up all the guns and have STANDARDIZED on one platform. At this time, it's the Glock platform across the three major calibers. 9mm, 40S&W and 45ACP. I do have a PPK/S in .380 for double secret backup, but I hate to practice with it and keep it around for purely emotional reasons now otherwise I would have given it to my brother's kid for a wedding present.
These are the guns I carry and they are the guns that get used as they were intended. Personal protection and practice/competition shooting.
My wife keeps a nice .22LR under the bed, but it would have died of "dust bunny suffocation" if I didn't take it out once a year and shoot/clean it for her.
So, to answer the original question, I've got the three major calibers and they all shoot exactly alike. It's what I carry and there's no trying to figure out what needs to be done to get it to fire when clearing the holster.
But that's just me.
