I have a Full and Compact size, they both shoot great. The compact is just as accurate as the full. They shoot as well as my P227's.

Both of them are currently out for mill work to add a Romeo 1 optic. Which leads me to my only frustration about this model, and that is Sig treats the P320 45 like a red headed step child. No RX model, very hard to find carry grip modules, slow to change to the new 2.0 grip modules, nothing on the radar to add the X5 style grip modules, and you have to ship the gun to Sig if you want to get an exchange kit.

Despite all that, I still love em.

I have a full size 320 45 and will get a smaller version 45 soon. I've got about 400 through it now with no problems.

My compact 320 9 is still humming along.

I like mine alot! Looking for a full size/small grip module to cut down to a carry version and use my 10 rd. mags.
