I like GunsAmerica for their search function. I like being able to filter according to caliber. How about everyone else? Anyone have any other good sites?
As far as commercial sites go, I prefer J&G Sales. I don't buy guns online, normally, but they're good for parts, ammo and accessories. When I eventually get my C&R license, I'll likely be ordering out of their selection of C&R guns as well.
Usually, as far as buying or trading firearms goes, I prefer to use the classifieds here....but for obvious reasons, I can't do that right now (check my location!).
And as for just talking about them...well.... is second to none!
