It is rare to find a Colt 1911 around here. This LGS usually only has a R1, but today he had this Colt O1091, a RIA commander (really nice for just under $500.), a Spartan V and the R1. It was a good visit, it's been a while since I been gun hunting. Needless to say I got the bug again.
You guys got some expensive transfer fees... most of the time shipping on gun broker is $30-40 bucks...transfer fee might be $20-30... All I'm saying is if you watch carefully on Gunbroker you're gonna find a good deal compared to his local prices. If the dealer is reputable and says the gun is new, I would buy a 1991 from them without hesitation. If it was a gun that cost a ton of money then of course I'd want to see it in person.
I got my last S70 Stainless, NIB, through GoingBroker for $940, plus $25 shipping, $15 transfer locally. Dealer had a return clause within 3 days (all you have to do is ask before you buy but it was also thru seller with over 1000 100% positive which is another thing to look for religiously imo)
I see the S80's for around $850 or so here in the New Orleans/Baton Rouge areas.
So, there ARE regional differences in pricing like on a lot of things but for the money asked, including sales tax (also a variable which may or may not apply in your case) I'd probably go online for this.
Just my .02. Of course, you could also, depending on any relationship you might have with your LGS, ask (politely and professionally) about discounts that may be available. He wants to sell it about as much as you want to buy it.
