Edd thanks for all your help. I ordered the cfe-9 wyatt extended box thinking that it would be the longest box for the gun but i'm taking it that they make diffrent lengths and the cfe-9 wyatt part# isn't the right one?? I just checked the order and it is still pending so i tried calling brownells to talk with somebody in the gun shop to make sure i'm getting what i need but they are closed today and i guess thats why my order is still pending. i've talked with them guys before and they have always treated me good and been very helpful but they're not there today to help me. If you don't mind can you help me out? do they make different length extended mag boxes? i tried going to they're website and plugging in the wyatt part # that i think u are telling me i need to get the 3.750..i looked under the specs for the cfe-9 but i didn't see the length..do you suggest getting the
cfe-12 to get the length? Thanks very much Edd for your help
