I was wondering what the value of a xdm 3.8 40 s&w was? i Want to upgrade to a 45 acp. so im thinking of selling my 40 3.8 xdm for a xds 45. Just wanted to know what a good price to take for it is? It is the all black XDm with a full size grip (16 rounds) 3.8" barrel, 4 (16 rd) Mag's, and the whole xdm kit it comes with? I have only put about 250 rounds through it and i keep it really clean. any info would help. ( The Gun im selling is the one i have my picture set to) thanks.
