I have a line on an as-new never fired M21 regular frame and one mag (no box or papers) for around $500 with fees & shipping (it's out of state & I will have to transfer it). It looks like these are going for that or a little more; at least it looks like a fair price. I have also found that Crimson Trace makes its laser grips for every Glock but the 21 - what's with that?? This pistol has the standard Glock rail on the front frame, not the Piccatinny, a minus, but isn't there someone who makes an add-on laser that will fit the Glock rail? Looks like an opportunity to me, based on the number of people looking for one at the Columbus, GA, gunshow last weekend...
