I spoke with the folks at my local range/gun shop, which does a tremendous amount of business, and they don't have any P30s, HK45s, or SIG P250s because NO ONE HAS WANTED TO SELL THEIRS (Most range rentals are used guns the store buys - I know of no range wealthy enough to use brand new guns as rentals).
Lotsa luck finding one - your odds are better if you just lurk at the range until someone shows up with one and you beg/plead/proposition him to shoot his.
You can also search here to see who has one that may be in your area. You could always pm them and offer to pay their range fees, if they would let you try out their pistol.
