Most J&G Sales firearms are trade-ins or excess stock from auctions. I have not had anything from J&G that didn't function and the descriptions are honest. The M10s are generally police trade-ins from all over the place. They are used and 30-40 years old and often show heavy holster wear. Mechanically, no problem. They add up quickly though. If you purchase a used M10, add S/H, transfer fee at your local FFL and your labour to clean and possibly replace the grips-why not shop locally? WWW.jgsales.comwww.simpsonltd.com
I've got a couple from J&G, and am very happy with them. Handpicked them myself from about a dozen they had, and they didn't have much holster wear at all. $169.00 plus tax.
