I have a few Colt DA revolvers, fortunately, bought before the prices went stupid. Funny thing is it wasn't all that long ago when I was able to find them at decent prices.
Back around 2011 I found a 97-98% 1964 vintage Python in a small gun shop and got it for $875 OTD. A year and a half later, I found a mint Detective special for $500 and a couple of months after that, I bought a '68 Trooper in the original box with the test target and all the paperwork for $600.
At the time I really didn't think much of what I was paying for them, I figured that I was basically buying at market value. Since then, even common earlier DA Colts like Police Positives have jumped in price to the point that I refuse to fuel the market by spending money on what I view as inflated prices.
The prices on vintage Smith and Wessons is going up too. Two days ago I was offered $1000 for a mint in the box M19-2. I remember that just a couple of years ago, they could be had for $450 or so. Someone mentioned .38-44 Heavy Duties, try finding a nice one for much less than $700 nowadays. Prewar .38-44 Outdoorsmans are regularly fetching upwards or $1500 and I have seen some better examples going for two grand or more. Even the lowly Highway Patrolman's have risen to above $600-700 for nice examples.
The thing is, all guns made before 1980 or so, have begun to skyrocket. When and if it will slow down is anybody's guess.
While the new S&W PC guns may be nice, personally I find the tapered slabside barrels to be hideous.
