I'll try to talk you out of it but only because you said so.
What can an Ed Brown Cobra Carry can do that your Dan Wesson CBOB can't do? They are same profile, they almost look the same, they will fit on the same holster, their mechanism is almost the same.
Will you feel you'll be able to defend your life better with the new Ed brown that you still don't have or will you feel more safer with your tried and true Dan Wesson CBOB after a CT brian, Ted Yost or John Harrison do a reliability job on your DAN Wesson CBOB?
Do you really believe the MIM parts on your Dan Wesson CBOB will fail during a fight that you always wish not to happen?
I defend my life with my Kimber pro carry 2 (with reliability job) and it never fails with weekly training in IDPA. Do you believe my kimber is better than your Dan Wesson CBOB? My kimber have more MIM parts than your Wesson. If you do i will exchange my gun to you and i will even pay for the shipping.
I shoot with someone in IDPA that shoots his Ed Brown Kobra carry. And what i always hear from him is how he loves the shootability of his friends Kimber SIS compared to his Ed Brown. Go figure!
We always want what we do not have and do not appreciate and make full use of what we have. 1911 desease is really hard to cure. But the 1st step in curing it is to accept that you have the desease.
I so wanted the Ed Brown also but what i have is a Kimber. I did a bobtail job on it and it now looks like and carry like an Ed Brown Kobra Carry. I even used the ed brown bobbed mainspring housing. So i don't desire an Ed Brown Kobra Carry anymore and just use my tried and true kimber in my IWB holster wherever i go.
At the end of the day if you have the money to spend and getting an Ed Brown Kobra Carry will make you really happy then get the Ed Brown and unload your Dan Wesson CBOB but maybe polishing your Dan Wesson CBOB and shoot it a lot and train a lot with it is better for you. Then when you brake your Dan Wesson CBOB which may not happen for being overused then you can get the same profile but a bit better Ed Brown Kobra Carry.
And then it will be very sensible to get the Ed brown because you have trained and been very experience with your Dan Wesson that you don't need any re-training and will have very familiar feel with and ed Brown Kobra carry.
But for now you are just wasting money. Get a Gun Site training instead, Get a reloading machine for your 45 ACP and shoot a lot of matches IDPA, USPSA, BULLSEYE. Your Dan Wesson CBOB is an excellent gun and is better most of of all the pistols. There are more ****ty handguns than your Dan Wesson. Your Dan Wesson CBOB is also a hard to find weapon and command a premium.
Just promise yourself that next time you buy a weapon you will be disciplined and get the weapon that you really like in a pricepoint that you are comfortable.
