Is there any disadvantages to an aluminum reciever commander. Strength, durability ect. Thanks.

Don't know about aluminum but I have a S&W 1911PD. Scandium frame.




Very light. A little snappy.

Not after carrying a steel framed one for 20 years

I believe the early ones tended to crack after extended use, but the manufacturers have had a long time to play with materials.

I have a Star PD with about 3 thousand rounds through it and it's holding up fine. I expect the same and better from my Springfield Champion Operator. It's that old saying about guns that are carried a lot and shot a little. I sure like the way both of them carry.

Shameless pic of the Springfield.

I have not yet had time to put a single round through my commander. Maybe next weekend.

No.

Modern day alloy frames don't crack in the amount of rounds you'll feed it.

Colt's aluminum frames are hard anodized. I wouldn't anticipate any issues with them unless you plan on putting an insane amount of rounds through it over time. If you do plan on that, then get a steel-framed Combat Commander. Bear in mind that SIGs, Beretta 92s, and other service pistols have aluminum frames and have withstood the abuse of military service and the piss-poor maintenance that goes along with it. I carry a Colt Wiley Clapp Lightweight Commander daily and don't have any concerns about it's long-term reliability.

If you can afford the ammo to crack a Lwt Commander frame, you can afford a new Commander. I wouldn't worry about it.

The Scandium frame is Aluminum with about 0.5% Scandium.

Adding Scandium to the Aluminum alloy can increase the yield strength by about 30% compared to other Aluminum alloys.

There is a difference in frame life. But the chances you will shoot it enough to find that life are slim. They are noticeably higher recoiling but much nicer to carry then a steel frame commander. If alloy frame is what you want I say go for it as long as it has a feed ramp insert or a ramped barrel.

The only real negative is with a traditional colt type feed ramp, being aluminum, they might get dinged up by some types of hollow points or steel mag followers.  Springfield and most others use a ramped BBL so that is a non issue with them.  I think ruger puts a titanium insert in their frame ramp.

If this happens EGW has/had an insert that can be added to the ramp area.
