So while I had a little time to kill listening in on a conference call this morning I put together a spreadsheet comparing the 9s, .40s and 45s. All info from Kahr website. Got tired of clicking around.
I don't see a way to upload a spreadsheet to the site so here are pics of each caliber but if someone wants the spreadsheet just shoot me a PM with your email.
9mm
.40 S&W
.45 ACP
