I bought two ten round mag from elsie pea store and received them last week. Shipping was handled very professionally; fast delivery and product came in a sturdy box. The problem I am having is that one of the mags I bought works fine will the other is deff. defective. I can not put more than 4 rnds in it and the bottom one seem to get stuck and i either have to tape them out or they fall out. Any one had similar problems with these mags, have any ideas on fixing it, and/or the process for sending it back? Also I assume I will be contacting Midwest Tactical Supply for the return correct?
