I did considerable research before buying an SRP. Mine is a .45. of course, 1.5" option, Baercoat, no magwell and is the sweetest shooting gun I have ever owned. I am not a particularly good pistol shot but this sucker makes me look like I am! At an indoor range, near my work, I was shooting 3" groups with Federal Ball 230 ammo with regularity - 11 yards and 4" groups at 20 yards. This without ever overcoming anticipation pistol jerks!The SRP comes standard with a 2.5" at 50 yard guarentee where as the TRS is 3". The SRP comes with standard sized grips instead of thin like the TRS. The SRP comes with a Magwell I think, and the finish. I think that those are the differences. Of course, either can be had with the 1.5" at 50 yard option (at least I think the SRP can). Anyone feel free to add anything that I missed.
BTW, not to state the obvious, but the markings on the slides are different:wink:
