WIW?: S&W Model SW40VE - 10 rd mags only

[04ctd]

buddy has one he is thinking about selling

http://www.smith-wesson.com/webapp/...57764_757752_757751_ProductDisplayErrorView_Y

i think they were closer to $500 when new, (judging by comments in reviews) he wants $300 for it, but they are $300 new now

and he got it when the ban was on, so he only has 2 10 round mags.
since I will need to buy 14 round mags,

looks like the mags are 30~50$
