Re: Help unload 38 S&W CTG
Okay, you've got a 5th Model Safety Hammerless, made between 1907 and 1940. It does have a safety. The thing on the back of the grip is a grip safety. If it is not depressed, the gun cannot fire.
Look at your third picture. Upper R/H part of the gun, above the cylinder and in front of where the hammer ought to be. See the round, protruding piece, with the checkering (cross-hatching) on it? There's one exactly like it on the right side of the gun. Grab hold of these two pieces and lift them straight up. That lifts the latch to open the gun. That screw, just forward of the latch, is the pin the latch pivots on. As the gun opens up, the ejector star will automatically rise and eject the cartridges. See, in your bottom picture, just behind the rear sight? Two rectangles that are a lighter color than the rest of the topstrap? Those are the lugs that the latch locks onto to hold the gun closed.
