Went on a search for a 10mm hangun to add to my collection(sigs/berettas/remingtons). I love the power of my .357 sigs and kinda like the "oddball" rounds. Thought i'd get a 1911 since i didn't like my other choices(glock). Picked up a SA 1911 Ultra Compact(tac sites, hogue grips...). E-mailed SA to find out that I'd have to change everything(slide, barrel, mags...). I originally thought i'd just get a barsto and have it fitted. Is there still a chance with this gun? I like the size and feel and haven't even had a chance to shoot it yet. Must I trade it off for a SA compact of Loaded? Your help is appreciated.
