New 9 round mag for thunder 380

Unless there is an issue of size and/or concealability while using the larger mag, I recommend them. I've got a total of 8 of the DLX mags. I bought them a couple at a time over about three years. Planning on getting a least couple more as I bought a second BT-380, used, about a year ago to use strictly as an under the pillow gun. For a while I loaded 9 rounds in each mag, but by personal choice and problems with my hands, not problems with the mags, I only load 8 rounds per mag. Initially the purchase was more about grip problems than wanting to carry more rounds. I have broad hands and always felt like I didn't have the best of grip when shooting. The longer DLX mags fixed that problem. For personal safety, I always carry one in the tube with safety off. When I finally "discovered" the DLX version, I was at the point of getting rid of the one I had at that time. Just an additional note, I load only 12 rounds on my 9UC primary carry mags and 14 rounds in my 15 round capacity M1 Carbine mags.
