I did a rough estimate. I can get a 35, put night nights or better sights on it, conversion barrels for 9 mm and 357 Sig and still be under the price of a decent 1911 (1000-1200).

Also I would get 3 magazines, be able to use them in my 27. Use my 17 mags in it if I converted it to 9mm and also be able to use some of my holsters.

The only reason I would convert it to 9mm is for new shooters to use. They would benift from the longer sight radius and lighter trigger. Also the grips can be modified for smaller hands.

A no brainier.
