I currently have a S&W 340 M&P that is my EDC and have recently come across a used but like new 360PD which is the same gun basically except for the fact it has an exposed hammer vs. my guns enclosed hammer and a titanium cylinder. My questions are what are negatives of the titanium cylinders? Are they fragile and likely to blow up if magnum ammo is used,do they suffer from flame cutting/erosion if really light magnums are used? I've also read that the Ti cylinders are very difficult to maintain and clean.

I don't know anything about titanium cylinders on revolvers so I don't know if anything listed above is true or not. Also why do the Ti cylinder guns restrict the ammo weights of .357 magnum ammunition to be used in these guns? For those here who own the guns with Ti cylinders what are the trade offs good and bad?,thanks for any help guys.

I had one and sold it. My experiences...

Good lightweight gun vs heavy recoil. Some have no problems with it.

The Ti cyclinder restricts weight because the recoil can cause some bullets to come loose from the casing and bind the cylinder.

The Ti cyclinder has a special coating to protect the metal. Once the coating wears off, the cylinder will pit. When that happens is anyones guess. Mine showed serious wear inside the cylinder after 1000 or so rounds.

Best advice, stick with the recommended loads, test fire 2 - 3 rounds of your choosen ammo, then check the remaining 2 unfired rounds to see the bullets show any signs of unseating. Also, don't use a bronze brush inside the cylinder, or on the outside. Once the coating is gone, there is nothing protected the titanium.

I know with the 340PD it has a warning on the gun that says don't shoot any ammo less than 125gr.
I've seen some pictures of damage done using lighter ammo on S&Wforum.

Thats one of the reasons I went with my MUCH HEAVIER (2oz ;) ) M&P340CT.
I'll see if I can dig up the thread.
