Need some Auto Pistol advice/ suppressor platform

[Wildbillz]

Hi All
I am concidering the purchas of one of three differant pistols. I would like to be able to (Legaly) add a suppressor to it later on. Anyone have any advice on any of the three models listed below? How do they stand up to use? Parts avaliblity and so on. I like the look of the Tactical and am leaning tward it. The OSS has the same look and I like most of what I see on it with the exception of the lock. Dose the SA come with a locking device built into it? The Glock while not having the cool Tactical look. Well it works and works. Mags are reasonable cost wise.

1, Springfield XD Tactical
2, Taursus OSS
3, Glock 21.

For the most part I am thinking that I want a 45Acp caliber. But if I got one in a 40S&W and got a suppresor for it, could I use the same suppressor for the 9mm that I curntly have? I am thinking that there is only a small differance in bullet dia that it would work but be a little louder then with the 40. Am I thinking right or will it not work?

Thoughts on the matter?
Thanks
Wild Bill

I have both the XD tactical and the Glock 21, and I shot much better with the XD. I also like its grip and ergonomics better. Zero failures of any kind with either one. I have no experience with the Taurus. The Glock has more flex in its frontal frame area, so I think the XD might handle a suppressor better.

Oh, and no internal locking device on the XD as I recall.
