Hey Tac-Safe, I ordered a RMR Capable G19 slide from OneSourceTactical.com. It is an aftermarket slide they actually produce. It took 2 weeks from placing the order to it arriving at my door. It took that long because I also wanted it custom cerakoted OD green. I'd imagine if you just went the stainless route you'd probably get it within a weeks time at most. I decided to go with an aftermarket slide because I do not want to alter my original Glock slide and wanted one in OD green. I do plan on ordering a lower receiver when funds allow and then I will have 2 glock 19s, one RMR'd and one Glock stock. Slowly building up my glock collection . Wanna kill these ads? We can help!
