Yeah thanks again to retroparts for posting the info. and thank you 18DAI for posting about the 4516-1. I have been wanting a compact 45 for some time. Hopefully your gun will be as clean as both of mine were.
Your all very very welcome! And I appreciate the response being a fairly new collector.
I just picked up my 4516 & 4506 yesterday. Got 'em even cheaper as I got my Cabela's card, used the points (and got a cool coffee mug & ball cap).
SO, for less than $800 got x2 top quality "real" pistols?!?!?!?!
Yeah, can't beat that. The 4506 needs a little cleaning & has a little holster wear, which is more like holster "polish" so I'm just gonna run with that & keep polishing her up

The 4516 is a gem! Smaller than my 5906 9mm. Can't wait to fire 'em!
I've a 4003 TSW in the box on the way I got for $405 on Gun Broker.
Gotta take a little break after this... that "guilty" feeling is coming over me
Here's a pic of the small collection.
With my x2 favs thus far being my 645 & 5906.
x2 K-frames 66-2 SS 357Mag & 19-1 Combat 357Mag(Dad's old service revolver). Both w/Hogues.
5906
645
4506 Nite sights & pachs
4516 Nite sights
& the 4003TSW on the way.
Just plain freaking works of art.
