I have 4 p320s, 2 compacts, 2 full size. 1 ea in 9mm and 45. All are 100% reliable with reloads at both ends of the spectrum. Light loads and full house loads. They are very accurate and have very good triggers. I think they are soft shooters. They generally come w a medium size grip module but my 45 compact came w a small. Which i prefer.
There is a “voluntary upgrade” for older style triggers. Is this a new or used gun?
