So my buddy has a colt 1911 A1 5" barrel, now I'm relatively new to 1911's and know what model it is. He has this gun in like new condition with only a trigger modification done (j believe he put in some metal parts??) and is willing to let go of it, and 500 rounds of .45 ammo for $500. Is there any way to tell what model it is or do they have different models?? Thanks in advance and I will post pics when/if I buy it this weekend.
