I've owned a few 1911's over the past 20 years, and I just last month I bought my first Glock (a 21 SF).
The only reason I wouldn't carry the glock is becasue it's so much thicker than the 1911 (thicker is harder to conceal).
If you not going to carry concealed, then that advantage goes away and I'd pick the one that is cheaper. In the USA, a glock is usually much cheaper than a 1911, but if that's not the case in Austria (which I admit seems odd, since they are made there...) then go with the best deal.
1911, XD, glock 21, sig 220.... as was said above... you can't really go WRONG with any of those choices. Personally, the only reason I chose one over the other is the way they feel in my hand. (don't like sigs and XD's, but I don't consider them inferior IN GENERAL, they just don't fit MY hand as well as a 1911)
- just my opinion, I Could be Wrong.
