I've had a Glock 19 Gen 5 for a few years now, but just now considering getting a red dot for it and I have no knowledge of the process. I've done some research but if anyone could share some wisdom or opinion, I'd appreciate it.
I landed on a Holosun 407k since 6 MOA seems like a good middle ground and budget red dot. I figure I have a couple of options: send the slide in to be milled or just buy a new slide with one already installed. I'm not sure what else needs to be done if I send it to be milled, like a mounting plate or something else I'm not aware of.
Alternatively, I found a package on a complete upper that includes a 407k, for about $100 more than sending it to be milled and buying the dot separately. The upper has some blowhole shit on it which is negligible and looks meh. But I guess I'll have a 2nd set of upper parts and don't have to cut the factory slide.
So I guess the trade-offs are looks and money vs convenience and backup parts. Thoughts?
