also what is the best out of the box 10mm 1911?

Since both guns you are considering are full sized, I would lean toward the 1911. The G20 is wider, even though it is lighter. 1911's have always been fairly easy to conceal no matter the barrel length. The big grip on the Glock is going to be harder to conceal.

Just curious why you want a 10mm? There are more options in the .45 ACP or .357 Sig for carry guns. The Colt Delta Elite is about the best 10mm I've seen so far. I'm not a Colt fan but that is a good gun.

i like the 10mm because from what i understand the 10mm slug is almost the same size as the .45 acp's but it has alot more muzzle velocity,

The only "problem" with 10mm 1911s is the cost, you're looking at almost twice the cost of a Glock for a 10mm 1911.

"Best" is up to opinion. There aren't many makers of 10mm 1911s these days. Colt is offering the Delta Elite again and that would probably be on the list. Dan Wesson had a number of 10mm 1911s but I believe they have been discontinued. If I could find a Dan Wesson in 10mm I'd go that route, if not probably the Delta Elite. Without going down the whole list of 20+ makers of 1911s the others that will offer a 10mm are Fusion, Nighthawk, and Wilson Combat as well as other custom shops, but general production guns in 10mm are few and fare between.

ETA: There's also the Kimber Eclipse II in 10mm.

I would go with the 1911 since as has been previously mentioned, they are thinner than a glock 20. Also, the fact that you have been shooting 1911s since you were 9 years old is always a good thing for a carry gun. While glocks are about as simple to operate as possible, its an advantage to have a carry gun that feels exactly like what youve been shooting your whole life.
