I’m currently giving the Macro frame a try. It’s a lot easier to shoot but is noticeably more difficult to conceal than the XL frame. Sig used new spring and follower designs to basically fit 17 rounds in the same mag body that previously held 15 rounds. I wish what they had done instead was use that new tech to design a 15 round magazine that was slightly shorter than the prior 15 round magazine and build the Macro around that. Then they would have had a gun with G19 capacity that was smaller than a G19 in every dimension (height, slide length, thickness).
