MSP,
The grip & frame of the Sig P228 is a tad smaller than the Sig P226. Try one on for size, I think you'll like it!
I own both the P228 & P226 in 9mm, and have given me a few thousand rounds (each) of reliable, accurate, etc. performance. These models are a dream to shoot, and I even prefer them to the Browning High Power, which is blasphemy too many avid shooters.
Telecote is "bang-on" about the Made in Germany/America variations.
My P228 was proofed in '95, making it a made/assembled in Germany piece. The P226 that I own has no proof marks and is a made in Germany, assembled in America item. Surprisingly, I thought that the made in Germany, assembled in USA P226s all had the stainless slide as opposed to the stamped slide. However, my P226 has the stamped slide. Nonetheless, it is an excellent firearm and would have to say that it sees the most range time.
On a side note, my P226 appears to be of lesser quality than my P228. This is only apparent in the trigger. The trigger pull of my P228 and those of other German made/assembled Sigs are surprisingly smooth. However, my P226 trigger is slightly rough, and not as nice as my P228's.
Hope this helps,
Jim
