This has probably been covered here before, but here's the question. I have a couple of pistols with sights I can hardly see. My wife won't shoot the Browning 1911 I bought for her because she can see the sights better on my other pistols. I looked at a product on Cabela's website, but the reviews were terrible. Someone told me they have used typewriter correction fluid. What can you guys recommend?? Thanks for your help. Tom
