Hello, I’m Larry. I just purchased a 1911 but not sure what I have. I did have the pleasure to speak with the previous owner. Apparently he purchased this firearm from Durys Gun Shop in San Antonio, Tx. It a Caspian frame (Foster). I understand that Foster is really a Caspian second. Slide is stamped “Model of 1911”. It is according to previous owner it is comprised of mostly Wilson parts. I can confirm upon field strip that it has some Wilson parts. S.W. barrel 5”. He told me that it was a “Custom Retro Wartime 1911A”. The Gunsmith that built this firearm was a Durys employee but has since retired. If I can figure out how to post some pics, I have plenty. Don’t have a url but are on my device in photos. Anyway thanks for reading and maybe someone can help me further identify this firearm. Great gun by the way. Shoots great. I really like it it a lot.
