Can a Sig Sauer 1911 45 ACP be configured or switched out to a 9mm or a 38ACP? ?

I traded in a glock29 in a 10mm for a Sig Saur sp2022 in a 9mm, the 10 wasn't bad, the kick was a little hard but I got used to it. And my uncles got a S&W sheild in a 40 and it was about the same as the 10mm. (The Smith & wesson shield is definitely not made for a left-handed person, the curve on that handle can take the feeling out of that spot between your finger and thumb very easily after firing it a couple times) So the 45 being the bigger caliber im wondering if it would have a big kick? A gun shop/gun range owner said with a 1911 being a heavier pistol that the weight would compensate for the kickback so I'm just wondering if it would be a good choice or if there is any place I could order a 38 Super (or is it the 38 acp) in a 1911? and if Sig Sauer made their 1911's in a 38 or if I could have one specially made by Sig saur? Wanted to ask around and explore options before shelling out like $800 for a gun like that.
