S&W 581 no dash/need advice

You can tell if it has had the modification buy looking inside the yoke for an M stamp near the model number. No M stamp, not modified.

What do you think of the 10/14/15's and where can I find them?

I like them all, the 14 Masterpiece and 15 Combat Masterpiece have adjustable sights while the 10 M&P has fixed sights regulated for 158 grain bullets.

I forgot to mention that the 581 lives in a small pawn shop that rarely has much gun inventory. This could be strike one. The owner so far has refused to provide the serial number when I explained that I wanted to know if it had be modified. Strike two. My brother, who has worked at a big gun shop in Albuquerque for several years, says a better choice would be either a Model 14 or Model 15 .38 special, derivatives of the famed K-38, or even the classic Model 10. Strike 3 as I respect his judgment when it comes to firearms. He owns many guns and has shot just about everything. They seem just as scarce.

Your intended use dictates what the better choice is, so what is it? Target work and plinking? Working gun for around the yard? Serious self and home defense? All three?

In my experience, well maintained 581s are significantly harder to come by than 10s, 14s and 15s.

If you prefer fixed sights over adjustable, and want both .357 and .38 capability, this is a no-brainer -- pick the 581 if it is in quality shape, as if it is the price is good.
