OK, so I have what might be one of the last batches of Browning Challenger II pistols made. The serial comes up as a year after the time they stopped making this model, which is the last steel framed .22 pistol that they ever made. It is in near mint condition (only way you would know it had been shot is if you open the chamber), I bought it unfired and have put about 500 rounds through it. I love it, it shoots amazingly, and very few people have one (which I like). The problem is that I bought this to be my target pistol at the gun club. My club is indoor and not lit quite well enough for the regular iron sites on this gun. There are no replacement front sites that I can find, which is another problem with this gun (only sold for a short time and almost no aftermarket upgrades available). So, do I sell it and buy a newer target or hunter model Browning or Ruger, make do, or keep it and save up for another rimfire I can put a fiber optic front site on?
