Congrats on the new XD-S! I really enjoyed putting some rounds downrange when I first shot mine. I used 230 gr. ball, and only ran about 160 or so rounds through it. That grip is pretty aggressive, too!
JoeBob Outfitters has the extended magazines
in stock, and they ship really quickly! Their customer service is great, too! I removed the collars from the extra magazines I ordered (they wouldn't fit in any of my magazine holders...) and they work just fine.
Great pics, JB! Enjoy your new .45!
