I just got back from Smokey's and had him look at it. He said it looks like a british S&W 38 that has been modified to a 38 SP. He is a very experinced reloader that used to load for the Lawton Police dept. Because of the front sight being so large gives him a clue to what it was origanily, can't say for sure but would bet money on it. The 38 is about 1/4 inch shorter and the chamber is cut for that, this one has been modified to take the 38 SP but the 357 won't go all the way in. Said as long as I keep the loads to 38 sp and not 38+P it should be fine. I have shot enough 38 SP (maybe 200 rounds of factory)in it that I think it will be OK. I posted a few pics on another thread but the icon is gone for that now and don't know how to upload a pic any more. I will hold off on shooting this till I get more info on it.
