Bought a brand new SR45 for $439. It's beefy and capable of any 45acp according to the manual. Haven't had a chance to fire it yet. Looks and feels much like the full-size SR 9 and 40. Detailed cleaned it. Strangely for a new Ruger, it wasn't too grimy inside. The striker cover, which appears to be more precisely cut than my SR9 is easy to remove and replace. One area of concern for now is the magazine lock up. Unlike my SR9, the SR45 mags take a slight nudge to seat properly and there is not that comforting snap into place like the SR9. Of course it could just be my SR45. Interesting is the enclosed manual. You get an SR9/40 manual with a 3 page supplement for the SR45 listing only a few parts and no diagram. Ruger provides its company logo decal as well. Hopefully it functions as flawlessly as my SR9. A unique mag loader comes with the SR45 that works better than the mag loader that comes with the SR9 and 40. Can't wait to burn some ammo.
