I have a Glock 19 that I carried for a little over 5 years.
I decided to finally make the jump into a dot a few years back. So I bought another 19 and had it milled and outfitted with an RMR and soon after switched to it for EDC. The round count on the other was getting high anyhow, and it has now has been retired. The current EDC I'm sure/I'd hope will go well beyond 5 years.
Glock 27. Was the second gun I purchased ever, probably close to 10 years ago. I don't carry it everyday, but it is my main option.
I recently picked up a Smith 360 though that is amazingly accurate for a snubby. I might carry it this summer.
I bought a S&W 915 in '92, I have a few others I carry, but most of the time, it's the 915. Especially in the winter. 1500+ rounds thru it and still as good as new. Proper clean and lube. Drawn twice, Once when a fugitive charged up the driveway at me and another when a guy put a knife to my throat. Saved my butt both times and I trust it for sure.
Admittedly I’m not a “one is none and two is one” type person but knowing how it turned out for you, would you have just went with your original pistol instead of buying a new one? Especially if the round count was not too high?
