There is an existing thread, “9mm 1911's”, at: http://www.msgunowners.com/t4188-9mm-1911-s
You can spin through all 7 pages and get caught up on 9mm 1911’s.
Regarding the 9mm SRTI Guardian: I have one. You will find it referenced throughout the above 7 pages.
For more info on the STI Guardian see: http://www.stiguns.com/guns/Guardian/Guardian.php
As far as 9mm 1911’s in general are concerned, below are comparisons I put together perhaps a year ago when I was searching out my 9mm 1911. NOTE: To the best of my knowledge the RIA 1911A1 MS is the Commander-sized 1911 9mm and is not being imported (drat!!).
If these charts turnout unreadable let me know. Send me your email and I’ll send them as attachments (Excel spreadsheets)
I hope you find this helpful. If you’ve got questions specific to the STI guardian drop me a line.
