New to Sigs and have a question. I've been seeing a few people talk about a website called Boogaloo Supply on a few forums and facebook and it seems they are some of the very few companies that still have Sig Slide still in stock. I'm new to the sig platform and mostly shoot my Springfeild XD9. I am interested in purchasing this slide with the Red dot installed ( im guessing its called RMR or is that the slide cut) is this still a good slide ? I would rather go factory instead of aftermarket/ third party parts. What do you all think?
