Replacement Receiver -- Lightweight

Have a 1973 Colt's Combat Commander, nickel plated in 45acp. Gun runs great but it feels a bit heavy.

Who makes an alloy Commander receiver that can be purchased separately? Caspian and Fusion don't list alloy Commander receivers.

Don't want a ramp-cut receiver. My Colt's barrel is unramped and has always worked fine.

JEM offers an alloy Commander frame and you can choose to skip the ramp cut.

JEM is great to deal with. I used them for my alloy commander 2011 frame.

Another JEM fan!

JEM. However, it is just the frame. You will have to swap all the other pieces from your steel frame and fit them as necessary. The frame is not finished so you may want to have it anodized or Cerakote it.

The frame will need to be anodized. Cerakote is not hard enough to provide durability to a raw aluminum frame.

@thinman you will need to find an anodizer in your area or one your FFL can ship to for type 3 hard anodizing. If you do find a local anodizer some will not accept the receiver from a non FFL for anodizing.
Almost as easy and cheap to buy a new or used lightweight

I didn't feel like engaging in a debate about the efficacy of Cerakote but since you've broken the ice let me weigh in.

Based on my experience with an aluminum frame in the mid-1980s, I completely agree with you. All of my aluminum frames are anodized for a reason.

Others swear up and down that there's no need to anodize an aluminum frame or at most just paint it. All I can say is you pay your money, you take your chances.

In addition to anodizing I highly recommend fitting a steel feed ramp insert in aluminum framed 1911s that don't have ramped barrels to prevent damaging the frame feed ramps. I put them in all my aluminum 1911s. If nothing else, they provide me with peace of mind knowing that they will prevent the kind of damage I experienced long ago that resulted in a pistol that would not even feed FMJ much less JHP ammo.

Excellent point. If I was building without a ramped barrel I would want a feed ramp insert.

The only alum frames I have built on have been ramped 9mm barrels.
Appreciate all the referrals to JEM. Had not heard of that company. As bladeandbarrel suggested, it does appear that by the time one gets done with frame purchase, maybe put in a steel ramp insert and type 3 anodizing, the project may be losing favor because of cost.

One can buy a complete, new commander-sized, alloy-framed, Tisas pistol for about what the replacement frame project will likely end up costing.

Quite right.

I don't know if this matters to you but Tisas uses ramped barrels only in their aluminum frames.

I'm okay with both ramped and unramped barrels. Colt's has always used unramped barrels, and my Colt's run fine. Have never heard a good explanation of why an unramped barrel is an advantage. But again, I'm okay with either.

A recent thread on this subject that you may find to be of interest: What is it about minor-caliber rounds and ramped barrels...
