I shoot mine on a regular basis, and I just believe a gun like that just DESERVES to be shot. It is too fine a gun to keep unfired. Of course, it'll be worth more if you think you may want to sell it one day if it's unfired.
It'll probably be a little less accurate than the P210, but I've never shot one of those. I think my P88 is about the same as my P9S as far as accuracy, but I prefer the trigger on the P9S.
Earl ( Earl's Repair Service ) uses the P88 as his carry gun of choice, and that guy has PLENTY of guns he could carry. TJ ( TJ's Custom Gunworks ) told me that there was not much that could be done to improve the P88 for trigger or feeding.
My P88 has never had a failure of any kind,and I've tried several brands and configurations of ammo.
The mags are not that expensive now that the ban is over. I just bought several for about 35-40 each. I think the mags that are not marked as LEO are still overpriced.
