I have been thinking about the ridiculousness of this rule, and think I may have come up with their ass-backwards reasoning. If you have just a pistol grip, the logical place for you to shoot it at Hot Wells, considering their setup, is at the pistol range. That's likely to lead to you (hypothetically) tearing up their target stands. If you have a stock on it, you'll be forced to shoot it either from the bench at the 25 yard range, or on the skeet range.Hot Wells is nearby and they require a stock. I don't wanna remove the pistol grip.
