I've warmed up to it but not fully. I view it the same way I view a 357 sig, nice concept but no great advantage to other cartridges. To me a 9mm or 45 can be used in most scenarios. I shot a range rental USP 40 my first time shooting a 40 and didn't feel a heavy recoil or "snapiness" others have described. I could've sworn it felt just like a 9mm. But I still wouldn't feel the need to own one as I have no use for it and didn't like the 10mm to begin with.
