Hi, I'm not a collector and I need some opinions/advice. I'm pretty sure I know what I'm going to hear, but I need to hear it anyway. I have my grandfather's 1911 which he carried in Europe while with the Canadian Artillery. Original holster etc. I love shooting it, even though I'm not very accurate with it and that brings me to my question. I'm almost 62 and I'm having trouble focusing on the front sight of any pistol, and this one in particular because it's just a very thin fin. Would it be stupid to think about putting different sights on it (I shoot well (uh, better anyway) with Tri night sights)? I'm guessing it would ruin the value of the gun, both financially and more importantly to me (don't plan to ever sell it) the historical and sentimental value. So, what do you think, and thanks for advice. Sorry, don't have a pic to post.
