From my understanding, the FMs are the only licensed clones. In theory that should me that parts are interchangable. In theory that is.
I know one of my local shops as FMs for $203, but those have the left hand side only miniscule safety. That's no big deal since that can be swapped out for a nominal charge. The finish on those FMs can be termed as painted on! The trigger broke a little heavy, but a nice shine and smooth SA 17 round mag *should* help the trigger pull a bit.
For a beater 9mm, I have heard that the FMs are a great steal and some folks use those as a foundation for a project gun. Over on TFL there's a guy who had a frame crack with only 5k rounds through his FM.
That detective 4" model on jdl's site sure is a good looking little pistol!
Century Arms (www.centuryarms.com) has the Arcus 94s available in SA, compact and double action models too.
