Ok... I'll take a shot at a few...
This is a 9mm Commander , or started life as one... lt is now a 9x23 and an amazing pistol...
Next is a stainless Commander from the 1990s IIRC I used for a carry gun for a few years... It is a good shooter and totally reliable... it is a 45ACP of course...
Here we have another 9mm Commander that became a 9x23... Shoots like a laser with a very powerful cartridge. The factory load is a 124gr JSP at 1470fps!! I load a Speer 124gr JHP designed for the 357 SIG and get a significantly faster result... I have chronographed some loads at over 1,600 fps from a 5" 1911 in 9x23. I expect from a 4" barrel it would be 40-60 fps slower.
Here is another stainless Commander, also used as a carry gun.
This one is a safe queen...
Another Commander, this time plain old 45ACP.
This stainless Commander went to Clarks for a meltdown for carry... a great carry gun now with no sharp edges. Other than having the melt down I added a new thumb safety, a slightly extended beaver tail (the original Colt cut the web of my hand) an arched main spring housing, skeletal hammer and light weight trigger... otherwise is a strait stock gun.
That should be enough for now... hope they are of interest.
