There is one more option, lets call it an extreme option, but once done you'll wonder why the factories won't do it. Have a dovetail cut into the barrel and a sight installed. I did this with my Bisley vaquero and it is sweet. I also had an extra sight made in case I wanted (I did) to shoot bullets of a different weight. 250gr lfn and 300 wfn. The down side is, it will require the services of a 'smith, which means it might be gone for a while and it does take a few $$$. But you now have windage adjustability and the ability to change front sights for different loads and just in case you don't go SLOOOOOOOW with that file. Good luck and good shootin' CRASH87
