Pro's and Con's of dedicated '22 pistols compared to 1911 conversions for Bullseye Shooting

First topic message reminder :

The title says it all.  I couldn't find an existing thread earlier today when I was searching, so here goes.

For bullseye, what are the reasons for and against building a 1911 conversion, compared to just buying a dedicated '22 pistol.

For that matter, what are the current sources for a bullseye-quality conversion kit, and will they just "drop in" on an existing bullseye 1911?

For those who need/want optics, what choices are there?

Do they come with a Bullseye quality barrel, or does that become a special order part?

Does the 1911 need to be modified to work at its best with a conversion?

Wonder if it works on a XD(M) 5.25 9mm?

I didn't read this whole thread, so maybe somebody has already made this point.  An awful lot of us who use a 22 conversion have put it on a "dedicated" lower and it stays there.  So it is in essence a "dedicated 22" in 1911 format.

Not sure about others, but that's pretty much what I plan to do.

It will be a 22, but similar in many ways to my 45, so it is likely to help me improve shooting the larger gun.
