^Blasphemy! A Colt in a caliber other than 45 ACP.
Then you won't like his siblings in 10mm, 38super also then
cant beat the 38super though
My wilderness carry is a custom 10mm, live it, fully supported barrel. The factory deltas need a supported barrrel. Havent broken a fram on a 10mm yet, not even a crack yet. And i load mine HOT, like the old Normas used to be.
Colt competition 9mm, save a few extra bucks for one
Go for the 45. My 8 year old grandson and his 12 year old sister were shooting mine a few weeks back and they thought it was awesome. For the most part, recoil in a handgun doesn't mean it hurts (like a big magnum rifle might). It really just means it takes a little longer to get back down on target for a follow up shot. Ammo price is the only reason I can think of to prefer a 9.
A proper hand gun guy will want a 1911 in their collection sooner or later anyway. In your case it's just going to be sooner.
And if you really like the 1911 I can't think of a better way to scratch that itch than with a 1911 that also has the prancing pony on the slide. So WELL DONE!
All the other replies about ammo cost and flinching with the gun are likely going to become real soon enough. So keep the other replies in mind when you buy your second hand gun. My own thinking would be to get a .22 as a cheaper gun to shoot and anti-flinch training aid. But a nice 9mm would not be a bad idea either. THEN a .22 to fight off the flinch you get from the other two.
Do you plan on taking up reloading soon? I would not seriously entertain shooting anything centrefire but 9mm without access to a good progressive press. Cost of .45 ammo is more of an issue than recoil management.
Another training aid for flinch is to throw a dummy round or two in your mags and video yourself or have someone experienced do it with you. You might be surprised.
.55-.65 cents/round, if you're shooting factory. It's very easy to burn through 100 rounds of pistol ammo if you're just standing and shooting at a target. If you bring more, you'll shoot more. My experience, anyway.
Have to get someone else to do it for you. If you can count, it won't be a surprise.

Dry fire practice and hard concentration on tracking sight movement have served me much better. I still suck by most standards, but this part of my training is going well.
