Hello, I am new to your site. I have recently bought a SA XD Service model in 45ACP. I have owned a SA 1911A1 for a long time. I just wanted something new and decided that the XD would be a good addition to my collection. I am a big fan of 45ACP so I decided to get this one to go with the 1911A1. It is always nice to have more than one weapon, that shoots the same ammo.
