    MAS, is this the same incident where a female detective was killed, and the fight was finally ended by one shot to the pelvic girdle? If so, I had met the bad guy in Mississippi a few months prior.

    This is exactly the one I was thinking of, thanks. 3 shots to the chest (total), a COM hit, even a contact shot to the top of the head (among others) and the dude was still salty until the last shot (after a speed reload under pressure) broke his pelvis and took the fight out of him. That sound about right?

    Pretty sure we are talking about the same incident. The guy soaked up 10 rounds, all said.

    MAS wrote the original article, the first discussion on the incident, in The American Handgunner. I had forgot the names. The apartment broken into belonged to my deceased first cousin who later retired from teaching in Florida. Until reference appeared here, I had not thought of this in years. I'm hoping that MAS will comment on whether or not shooting the pelvic girdle is considered to be a valid tactic. Not all agree that it is. Reading about this terrible series of events made me conclude that the bad guy did not know he was dead and continued to act. This comment makes no sense, but I have no other explanation unless I attribute his prowess to Satan.

    Willie, since you believe you may have known the perp in that case, I'd be interested in your take on the guy.

    Solid pelvic fractures have a long history of dropping the recipient. It's a "mobility kill" thing, best used to anchor a perpetrator in a contact weapon/disparity of physical force situation and would not be my first choice on someone armed with gun or explosives. The pelvic shot had a solid history of success with the NYPD Stakeout Unit: see "Guns, Bullets and Gunfights" by Jim Cirillo and "Jim Cirillo and Tales of the Stakeout Squad" by Paul Kirschner. Steve Chaney stated he was convinced that what he called the "hip-bone" shot was the only one that anchored the perpetrator in his death battle in Baton Rouge.

    MAS, none of us could see a fit between him and our relative. The man kept to himself and had little to say. This was over 40 years ago in a part of the deep South still influenced by the provincialism of the past. Had he acted stupid and met his end, it would have made no difference to the law once a background check had been done. That sounds ignorant but is a fact that I can't explain. The predator in him no doubt allowed this creep to figure out where he was.

    Sorry for the necroposting, but I just read about this crazy 1977 incident. PCP is one helluva drug - apparently the perp was still trying to crawl despite 10 rounds (3 lethal) and a busted hip (good thing he didn't have a gun at that point).

    And while slightly off topic, I have to say Officer Linda A. Lawrence's career seemed cursed from the start. She started in 1969 as an undercover for the Tangipahoa Parish Sheriff's Office where she was used as a decoy to obtain an illegal abortion from a local activist doctor. She wound up suing the Sheriff for intentionally ignoring her signal to enter until after the doctor began performing surgery!

    With a mere $10,000 verdict ($65k today) and unable to find work she served in the Army Reserves until finally hired on by the Baton Rouge PD in 1977. 6 weeks after completing that academy, she was killed.

    William Shatner also narrated a 1991 training video ("Ultimate Survivors") featuring this shootout.

    Interesting but not the failure mechanism related to the OP's concern, which is flame erosion of the forcing cone and maybe the top strap too.

    Forcing cone erosion is an issue in heavy use revolvers of any caliber when lighter than standard weight bullets are driven at higher than standard velocities. You're literally blasting the forcing cone and top strap with high velocity blasting media and you're wearing out the machine. What's more troubling than that is forcing cone splitting. The K-frames in .38 and .357 are more susceptible to this because the barrel root is much thinner than the N or L frame cones and doesn't withstand the wear the larger frames do. When the forcing cone splits, that barrel is done. Erosion can be addressed by setting back the barrel a thread and re-cutting the cone. Splitting requires a new barrel.

    More concerning is the growing lack of pistolsmiths who actually know how to do those processes well (or at all) in this 21st Century AND the growing lack of spare parts.

    If you have one (or many) of these treasured revolvers, I'd suggest you shoot standard loads, with lead or plated bullets and to not see if they'll digest as many rounds as your Glock 17 will. Those of us old enough to remember carrying and training with them also recall we didn't do 500-1000 rounds per day with them. There was a reason for that.
