CDNN has had a slough of the 320s for reasonable $.
That Walther Creed for $250 and mags for $20 is really tempting too.
The 320 xcompact is the only one I'm really interested in. It could be replicated/assembled from other models and grip modules, trigger, etc except for the optic ready slide, but seems more hassle to do it that way, and probably more costly than just getting the Xcompact at a decent price.
