$1300 or $300 gun doesn't matter, what matters is shoot what you shoot well and what you have confidence in. I have carried a sidearm for a living for 23 years and confidence that it is going to go bang when I pull the trigger and the projectile is going to hit where I intend it to are all that matters. I started off carrying a Glock and then my agency switched to a Sig. When that happened my qual scores went down from an average of 245-250 out of 250 to 225-235. The weapon was just not a good fit for me and as result I had more malfunctions and less confidence in it. I carried it for 7 years until they let us carry personally owned Glocks and my scores immediately went back up. Early in my career in adverse field conditions, a Glock save my life. If it had been a Sig, maybe I would be carrying a Sig. Point is carry what you have confidence in.
On the subject of striker vs hammer: I carry concealed daily, sometimes in a holster on my hip, but most often IWB appendix in a kydex holster with an untucked shirt. Your mileage my vary, but the amount of fuzz, gunk, sweat and grime that gets into the hammer area is substantially more than gets into the back of a striker fired gun. Does it matter, I don't know, but I always tried to keep that area clean on my Sig. DA/SA vs striker fired from a safety aspect is a wash for me. I have never felt unsafe holstering a striker fired gun.
Several people mentioned evidence and the fact that it is going to go away for a while. My agency puts it in a nice cardboard box, securely zip tied and it stays protected in a climate controlled evidence room. I have been in other evidence rooms where the weapons are literally stacked on shelves in piles. Those guns get scratched and dinged. Others I have seen put them in sealed plastic bags after the CSI people get done with them, so any moisture in the air gets sealed into the bag. After several months or longer, depending on how fast justice moves in your area, you get no billed by the Grand Jury. You think you're going to get your gun back, but wait, the Plaintiff's Attorney in the civil suit that was brought against you has requested the gun be examined by a firearms expert where it is going to be disassembled, fired, and otherwise fat fingered. Every aftermarket part you put on the gun is going to be scrutinized and that punisher emblem you stippled into the grip is going to get photographed and displayed in court. Be prepared to wait a while.
