I've been looking to get an RDS for my PPS .40 (gen 1) and was hoping maybe someone has one they have put one on. I'm trying to avoid cutting the slide and use a mounting plate that would slide in the rear sight dovetail. I'd appreciate any recommendations on a good mounting plate or a good RDS that doesn't cost hundreds of dollars. I'm not opposed to "knock offs" but haven't bought any as I'm worried they will break after actual use. Thanks!
