Had an old LLama and it was sloppy and loose, poor accuracy, but did work. Bought it used and chalk it up to "get what you pay for".
My shooting partner's father still has his 1911 from WWII, it shoots anything in the mag, and will hit what you aim at. Ball,JHP,FMJ, old ammo, new ammo doesn't matter. Action like butter. I would love to own that one. My Kimber Ultra gets better every year, and my S&W 1911, is getting there, kinda like fine wine, or brandy, gets better with age. (and routine maint.)

“The 1911 pistol remains the service pistol of choice in the eyes of those who understand the problem. Back when we audited the FBI academy in 1947, I was told that I ought not to use my pistol in their training program because it was not fair. Maybe the first thing one should demand of his sidearm is that it be unfair.”
