Blkher13 asked:
How many rounds do you think the average shooter burns in their main gun?
I don't know enough shooters nationwide to answer this for the "average shooter", but most shooter that I know only visit a range two to four times a year and then only expend 50 to 100 rounds. So, to answer your question, I my experience suggests it is somewhere on the order of 200 or so rounds per year.
How often do they do Minor parts changes? Recoil spring swap?
Minor parts changes are made when things break.
I don't know anyone that has made a recoil spring swap (apart from owners of Taurus PT-111 pistols who replaced the factory plastic recoil spring assembly pre-emptively with a stainless steel after-market one).
Do you clean it properly and inspect ?
Every shooter I know is "religious" (I put that in quotes because most shooters I know, I know through church) about cleaning their firearm after shooting it.
I’m just trying to understand why some people seem so scared of needing to put some work into a machine.
Apart from my 93 year old father (who leaves his fired guns for me to clean during quarterly visits), I don't know anyone who is "scared" of cleaning their guns. Even in my father's case, it isn't as much a question of being "scared" as it is that he doesn't have a lot of energy at his age and cleaning his gun(s) is a task he can leave for me without significantly damaging his gun(s).
If You buy a car used or new do you look at it first?
I mean run it through not just stand back and look at the exterior?
Why not for guns?
Recently, I have bought all of my cars/trucks used from a used car seller offering a 12 month/12,000 mile warranty on all the mechanical systems of the vehicle. They have a third-party shop conduct a 109-point inspection of the vehicle and correct any deficiencies before they put it on their lot. When I buy from them, my inspection of the vehicle is rather superficial as I know I can rely on the the inspection done by the third-party-shop (since I use the same third-party-shop myself for maintenance).
If I were to buy a used vehicle from an existing owner, it would go to a third-part ASE certified shop for inspection before I put down a single dollar on it.
And, regrettably, when purchasing a used gun, I lack the ability to do Magnetic Particle Inspection on the functional parts of the firearm, so I have to rely on a visual inspection of the bore, the bolt and the other parts of the gun.
