Trying to choose between PPS M2 and P938

I'm looking for a single stack 9mm to replace the G19 I usually carry. I'd like something smaller and easier to conceal in the summer.I've narrowed it down to either a P938 or The PPS M2.My local gun store has a PPS M2 on sale for $375. I like the feel of it, but compared to the P938 it seems quite a bit larger. I'm concerned that it'll be basically the same as trying to conceal my G19.I can grab a P938 Extreme for $640 (no tax on this one), or a P938 SAS for $700 (taxed). I like the SAS but not sure if it makes any difference to cost me $100 over the Extreme.I'm comfortable with 1911 style cocked and locked so that's no issue.TLDR: PPS M2 vs P938. P938 Extreme vs SAS. via /r/CCW https://ift.tt/2HdK1Mk
