Titanium handguns?
I am fascinated by Titanium and its alloys and have wondered why custom gun manufacturers don't use it to build guns. I cannot imagine how lightweight and reliable a Titanium 1911 might be. Any thoughts?

It appears they don't sell them in US. Interesting looking guns for sure.

Isn't titanium brittle? If so, then it may not be the best metal for a firearm.My guess is this is the reason why some titanium firearms have carbon or SS key parts to handle the pounding.

Shame on me for knowing so little about titanium. But I have seen titanium hammers for carpentry.

Titanium is stronger, lighter and harder than steel...buts its too hard and when it breaks it almost breaks like glass...even tho its stronger it is not used in barrels and cylinders or sometimes slides because it can do worse than just crack.... but the frame of a gun can safely be made from titanium

Titanium is not brittle, and is not prone to cracking. Near pure, non alloyed titaniam maintains the same tensle strength as mild steels at about half the weight. Even though titaniam is about 1/2 again heavier than aluminum it maintains nearly twice the tensle strength as most common alluminum alloys. The problem with using titanium is that its tough to machine as it becomes soft at fairly low temperature and tends to smear, gauld, and clogg cutting tools. It is also verry difficult to make castings from titanium because it will actually burn away in open air well before it reaches its melting point. It has to be surrounded by an inert gas sheild or processed in a vacuum to be cast. For these reasons titanium becomes expensive to form and manufacture. Contrary to popular belief, titanium is not super rare and is in fact one of the most common metal elements. It is the diffuculty in handling and machining, ect. that makes it expensive. Also strength and light weight are not the only desirable properties of titanium. It is also prized for is exeptional corrosion resistance.

It's not a 1911, but Sig has the P238 Rainbow.

Caspian has titanium 1911 frames.

Motorcycles have been using titanium for exhaust systems for almost 20 years (at least in the aftermarket....more recently, the factories have been doing likewise). In the early years, cracking was not uncommon.
Not sure what they have done to address that, but I am not seeing cracks in modern Ti exhaust systems. Given that exhaust systems experience low-grade impact force, but significant heat... I will speculate that the forces common to an exhaust system and a pistol frame would be substantially different...to the extent that I would look to someone with far more expertise in such matters than I. |

As for guns, I have a Taurus snubnose 44 Special made with a solid titanium cylinder and frame. (Kinda weird when you have a gun that a magnet won't stick to.) Barrel is a steel liner and titanium shroud. 19.5 ounces 5-shots. Not hard to shoot with the ported barrel.

Titanium has some expansion issues when heated.
Taurus does indeed use this metal on some of it's revolvers and some cylinder binding on a few of those titanium models has been noted. By far though,the gun market is going to polymer frame everything and stainless cylinders and slides. The weight reduction is'nt worth the hassle if the gun has to be retuned to make it work after it's bought. |

+1 on Caspian titanium frames. I don't own one (very expensive), but a friend of mine does and he even let me shoot it once (it was a plain single stack.) To me, it felt fine. Sort of like the weight of an aluminum frame with the bit of mushiness of a polymer frame. This is not from any in depth evaluation, but it seemed fine to me. Still, I don't really understand the reasoning (other than being able to shoot +p ammo) of titanium over aluminum for only weight savings. I do suppose that titanium frames would last forever as its modulus of elasticity is good and it is not prone to stress fractures.

The S&W 340PD has a titanium cylinder. Here it is noted in the description on the S&W website and here is a writeup from Gun Zone.

As for titanium 1911s, you can use it for the frame, certainly, although it would be expensive, as others have pointed out. You wouldn't want to use it for the slide because it needs to have a certain mass, and the slide would have to become significantly larger in thickness and size (it'd be rather strong, though). The barrel would also have to be thicker and larger, so that's probably out. None of the small parts inside of the gun would benefit from being made of titanium in any practical sense. Since aluminum (or even plastic) seems to work well enough for lightweight frames at a far lower cost, there is really no point in using titanium in handguns except perhaps for the novelty of it. Well, OK, if metal fatigue is an issue with aluminum frames, then a titanium frame likely will not fatigue, much like a steel frame--I'll give it that.

I know little about metallurgy other than the basic stuff. My main experience with titanium is with bicycles. I have a mountain and a road bike with Ti frames and components. Holding up well so far after years of use.
I owned a S&W 340PD for 7 years and shot a few cylinders of 357 through it. Recoil was not comfortable and sight acquisition following shots was lacking for me. I used + Ps in it when I carried it. Still for S&W to use a titanium cylinder the strength to take the shock of a 357 magnum must be considerable. Even in the few reports of cracking on those the scandium was the problem, not the Ti.

Crosshair,
it was a 44 mag... though specials out of it could be good, a mag out of that light of gun would have significant recoil and jump |

My backpacking carry gun is a Taurus model 617 7 shot .357.
It has a lange cushioned grip and a short ported barrel to improve handling. (I would have preferred a longer barrel but... that's what was available) It has a stainless barrel liner but the cylinders are not lined. I don't shoot it much but I sure am happy about the light weight. With ammo removed it feels like a plastic squirt gun. We've travelled many, many miles together. |
