So, with the guns I get excited about, I keep a close eye on pricing from as many sources as I can, and usually, the difference in retail pricing is negligible. Sometimes you find the odd great deal, and sometimes you find the crazy flyer that is asking obscene prices. When researching pricing for the M&P 9MMs and .40s though, I see such a huge difference in pricing for NIB guns, I don't know what the average retail for one should be. I see lows of $400, and highs of over $600. My preferred local shop has them new for $589. Support for local goes out the window however, if the same gun can actually be had for $450 after shipping and FFL fees. So, in a nutshell, what's an acceptable average retail for this gun?
