[QUOTE="ldp4570, post: 1047165, member: 5168"] The purpose behind the pin is to keep the barrel from coming loose during firing. S&W dropped this step in the production(save money) and went with the "crush press/torque" step for securing the barrels. As to the recess charge holes, everyone says it was due to keeping ballonhead cases from coming apart during firing, well none of the magnum cases were ever ballonhead, only their smaller twins i.e. .38spl, an .44spl. This was for those folks (read Elmer Keith & The .44 Associates) who still were hotroding the .44spl caseings they had on hand. Funny cause S&W never thought to recess the charge holes on the non magnum calibers that most folks were using early in the 20th century, and alot of that ammo was loaded in the old ballonhead caseings i.e. .38spl, .44spl, .45LC, .32-20, and many others. Granted ballonhead brass wasn't as strong as solid head brass, and there wasn't as many guns blowing up as some would have you think. Its also rare to find any ballonhead cases anymore, most that remain are in peoples ammunition collections. Yes folks do collect ammo, I have my own, from a small Kolibri round, up to 40MM(Demilled trainer). Now the other issue is on the .22lr revolvers. Since this is a rimfire round the charge holes on all of S&W's revolvers are recessed for safety reasons, since on some of their revolvers the recoil shield does not completely cover the cartridge rim from being struck if the gun is dropped or the shooter slips and falls while the gun is holstered striking something hard. Also since the rimfire is technically a ballonhead case with the priming compound in the balloned rim, there have been cases where the rim would fail, keeping it recessed inside the cylinder would keep the cases rim from becoming a small handgrenade. It does happen, I have a friend from high school who's .22lr singleshot rifle had a case fail, he wasn't hurt bad, but does still have a couple of scars on his hand from shrapnel from the brass.
