I got my first 1911, a SA "loaded" used from a local.
Being an absolute dipshit when it comes to these, I did not know how to perform a complete safety and function check...until AFTER I bought it. Turns out, this thing had problems. I dont know if it was from the factory that way, or if the guy I got it from did a little "home" gunsmithing.
In any case... the gun would allow sear movement when pulling the trigger with the safety on... so much so that when I later dropped the safety, the hammer would fall to half-cock. In addition, I felt the trigger pull was much heavier than other 1911's I have shot, and the safety did not engage/disengage with a firm "click"
I checked with a couple local smiths... and parts and labor were quoted around $200. So, I called up SA... to see if there was a chance they might fix it under warranty..... and off to them it went. Their lifetime warranty only covers the original purchaser..... but the lady on the phone said all I could do is send it in, they would examine it... and sometimes, for a safety related issue, they will just fix them even though the warranty did not apply to me.
Man, I got it back today after being without it for around 2 weeks. They fixed the safety/sear issue, did a trigger job, and now my safety also has a firm click on and off. All covered under the warranty... didnt cost me a dime. Thats the kind of customer service that will be keeping me buying more Springfield products in the future. Wow.
