Called S&W customer service and they also shipped me a set of rear and front sights, no charge and no questions asked. You gotta love there customer service. Only problem is sights will not slide in but is very tight at the very beginning. Thought it would go in most of the way and I would just need to tap it in slightly but not the case. I'm concerned about hammering it in since its an aluminum slide. Might just take it to a local gunsmith. Any idea of whats a reasonable charge to install?
