That's how I started, I was a newbie to the Ruger revolvers,only had a few .357 Sixes and GP's..... I saw that full lug 4" .38 in the pic above on GunBroker about 3 years ago, a dealer in NM was selling a bunch of them listed as security trade ins.....I was like "A GP100 in .38 Special??!" and I had to have it, never even knowing such a thing could exist. I thought "One of the strongest .357's ever made, chambered in .38....how cool is that!" Then I HAD to have one with the half lug, then I started looking for the .38 Sixes, and then more .357's to "balance" my collection out.......you know how it goes......
If you like S&W's, don't forget the 38/44 Heavy Duty......it's an N-frame with a 4" or 6" barrel, chambered in .38 Special. Made for a Hi Velocity .38, in the era prior to the .357, but it's neat..........it's still an N-Frame with .38 Special stamped on the barrel!

For some reason Smith kept making them well after .357 revolvers were common.
I did just buy 3 more Service Sixes, chambered for, none other than .38 Special! A bunch of security trade ins must have just come on the market or something.
One of my "Grail Guns" is a 4" blue Service Six with the "US" stamp on it, of course it's a .38. Last one I saw on GB was a minty one that went over $1,000.
People who aren't infected by the ".38 Special Ruger DA disease" don't understand........even my dealer is like "Why do you buy so many of these .38 Rugers........you know you can shoot .38's in the .357's right?" And I was like "No, you just don't get it......."
I even heard of one guy who was having .38 Special Service Sixes and GP's reamed out to take .357's, and my heart just sank......
I even e-mailed Ruger asking how I could special order a 6" full lug blue GP100 chambered for .38 Special, just so I could have the first one in existence, but they didn't even bother to respond.

I'll settle for my .357 Redhawk, I guess, as my "ridiculously overbuilt and heavy for the round" revolver.
I have always had a thing for massive, overbuilt revolvers. I shoot 158 gr. .38's out of the Redhawk and they feel like .22 shorts.
