Pard:
I had been looking for a reasonably priced mil spec .45 for Wild Bunch and have done some online research in that vein. I decided on an RIA. The Auto-Ordinance .45 prior to the Kahr arms acquisition have reportedly been hit and miss, mostly miss. Since Kahr Arms bought Auto-Ordinance, quality has greatly improved to the point of "desirable demand" for them - they are hard to find and are holding value.
Now, if you plan to use the AO as a platform to customize, it is probably worth the $375 - but you can get a nice RIA for $400. The Kahr AO is over $500 but as mentioned, hard to find. Try this site for some more opinions
