No, there's no rule on it, Justine.
Wow. How cute. No one has ever attached an extraneous "e" to the end of my name in an attempt to imply that I'm a girl. Verily, sir, your insult is so original and devastating that you have dealt a grievous blow to my fragile self esteem.
Of course, now that I've addressed your insult, I'm sure you'll make an excuse to try to cover it up. Let me guess, your finger slipped when you were typing? That always seems to happen when people who have a personal problem with me send me an email or post.
There is, though, the longstanding argument that comes up whenever someone decides to fan the flames of this topic for no real good reason other than the desire to toss in their opinion.
The only one fanning flames here is you, Rich. Heck, the OP isn't even asking about a straight up pistol grip, rather he's asking about a full stock with a pistol grip, so I'm not sure why you're so upset about it.
My experiences shooting shotguns under practical circumstances have shown that there isn't a huge advantage to be gained by installing one of those stocks on the gun, and that perhaps the stock isn't worth the cost. Nowhere did I pass judgment. I simply made a suggestion.
How many arguments have we seen on this topic?
What? Discussions on traditional sporting stocks vs. pistol gripped full stocks? Not many. Certainly there's not all that much controversy there, as either is a functional and fine choice. My suggestion was simply due to the fact that spending the money on an additional stock might not have much of a net benefit. I'd certainly had made the same recommendation if his question had been reversed.
Did you *have* to jump on it this once?
Project much? I didn't "jump" on anything. I made a simple post with a simple opinion, and evidently you just couldn't handle that for some reason.
Could you not have simply answered the question, if you had a valid answer that is, and simply skipped the topic just this once?
As pointed out above, other variants of the shotgun come with the tactical stocks, and they can probably be ordered from FN, or failing that, Midway or Brownell's.
And yes, as always, I have already received a warning on the topic. Not surprised, but a little disappointed.
Perhaps you ought to consider that an invitation to re-examine how you choose to interact with people with which you disagree.
