I just won a nice SD9 2.0 on a gun raffle and there is an option to switch it for a 9mm Shield 2.0. Not being familiar with the SD9, is it a better deal than the Shield? Price is about the same.
Shield all the way. SD9 is blowback, you won't like the way it shoots. Its size is also more similar to a compact M&P, the Shield 2.0 will be smaller. Note the Shield 2.0 is not the same as a Shield Plus.
