Ive been a strictly iron sights on pistols guy my whole gun owning life but I’ve been converted and want to get a red dot on my Gen 4 G23. Started looking for optic ready slides and there’s a plethora of manufacturers. Is there anything in particular to look out for with aftermarket Glock slides?

Not a Glock guy but they run the gamut. I'd stay away from the cheapest ones, and my personal preference is to not buy slides that have aesthetic holes in the sides and top, as those are places for crap to get in and jam the gun up.

The issue is that the slide contains a lot of the dimensions that make your gun work reliably. With that in mind, sending your existing slide to a reputable gunsmith to get milled for an optic might be the safest option.

I put together a P365 with a pretty expensive aftermarket optics cut slide...and it will only feed NATO/+p loads, and only for 100 rounds or so and then it needs to be cleaned. Very gritty to rack. Hoping it breaks in over time because I have a lot of money in that thing.

Sending the factory slide in to get milled actually sounds like a really good idea that I hadn’t put any thought into before. Seems 90% of the slides I’m seeing for sale have all sorts of windows cut into them. Plus since apparently nobody likes .40s anymore the G23 seems to have less compatible parts available.
