I just bought a P30 V3 in 9mm.
I like DA/SA hammer-fired guns, mainly because I like shooting them in SA. The V3 is DA/SA. I prefer the de-cocker-only version, rather than the P30S with the external safety. I carry my DA/SA pistols with a round in the chamber, de-cocked, and on fire, so the standard P30 has exactly what I need with nothing I don't. I chose the standard P30 instead of the long slide because I'm going to install a threaded barrel for a suppressor, so length is already playing against me and the suppressor negates any benefit gained by longer dwell time in the barrel.
And since mags are compatible, it only makes sense I pick up a VP9 now and install a threaded barrel in it. I'm using my rebate to buy more mags.
ETA: As far as the rebate is concerned, make sure you're the first owner, it comes with a receipt from a retail store that shows the store's info, your name, and the model you purchased, and that the price they're advertising isn't actually the price after MIR. This will ensure you get the best price and actually receive your rebate. The fine print on the rebate form is very picky.
