Anybody use a dovetail - if so do you like it - Ive been thinking about getting a 4inch one with a Black Gold sight and was wondering if they hold up well - do they stay sighted in if removed and do they help any with accuracy being out further than norm - i don't like the idea of removing a sight, thats why I'll probably get the 4in, and hopefully find a case that will accommodate for that. - It's just a preference thing for me - thought I might try something new - all opinions welcome.
