I purchased a XDS 4.0 in 45acp and took advantage of the one time discount to purchase some accessories. The mag holder is absolute garbage and have tried several times to voice my complaint. Several times it was returned as a unmonitored email even though they had a actual name attached to it. I've tried several others and still no response from anyone. Has anyone else had these problems with the holders? Being ignored by the personnel at Springfield? I find it unacceptable. I would like the magazine holder replace with one that actually works on both slots.
