I am going to say I have only regretted buying one firearm and I no longer have it. So I may over research before buying. I was thinking about a Range officer. Until I found out sight options are limited. I like XS big dots. They took some getting used to and some practice but I like them up to 30 yards. Looks likje a set for a range officer is about $200. Add for front strap checkering and time to have the mods done so maybe spending a little more up front is worth it?
