Is this some kind of test for us or are you looking at this gun to buy it? Either way we need the following:
While there is no precise method to determine the exact number of rounds fired through that 1911, combining visual inspection, performance testing, and historical context I/we, can provide a reasonable estimate. We need a lot more to give you a reasonable idea of how many rds have been through that gun. Any service records wit the gun?
Why no internal barrel pics—if barrel is indeed original? Need to look for signs of wear or pitting inside of barrel. A smooth shiny barrel indicates fewer rds through the barrel. The photos need better lighting to see the wear on the slide and the frame. I would want to measure and test the spring. Since we can’t see the wear well on them w/o better lighting it s hard to tell. How often was it used? I would want to put it together and rack it numerous times to see if it hangs up, jams excessively which it would indicate if it was shot extensively. If I were buying it I would want to shoot it to evaluate the accuracy at various distances. A decline in accuracy can indicate wear from high usage. BTW, if I want to shoot your gun I pay for range time and ammo for my evaluation… I never put that on owner.
I want to know if the gun has been used for training or competition?If so it may have significantly more rounds through it.
Competitive shooters often fire 400-600 rounds per session. If the owner is a regular shooter, this can add up quickly. Was the gun used in competitive shooting? If yes it is often fired 400-600 rounds per session. If you are a regular shooter, this can add up quickly.
Ifbthis is some kind of test for us then tell us what for? I assume there is some element of involving us in some sort of test? Since your post starts out with Riddle me this. Maybe, your screen name should be “ Joker” instead of “Lucky.”
