I use to think that way about my HK P7M13 pistols. I was used to shooting revolvers, 1911's, and semi-auto DA/SA pistols for over a decade. Then I saw my first HK P7M13 in a store and after handling it for just a few minutes (dropping the empty magazine, inserting a new -empty- magazine and dropping the slide) I realized that it was an amazing, superior semi-auto pistol that was inherently quicker to conduct combat reloading, and was super safe because of the squeeze cocking mechanism. I purchased two of them right after examining that HK P7M13 for the first time and I learned that they were two of the most advanced and accurate/reliable semi-auto 9mm pistols that I ever had the chance to fire. They do get hot after a box of 50rd, but, not so hot that you cannot continue firing them. That's a myth.
Anyway, that was the same experience that I had with my first Steyr Aug. It was different and I thought complicated. But, after I handled it I realized that I was wrong and it is a superior combat rifle. Certainly equal, and in my opinion, better than any of my Colt AR15 rifles. The price is off putting, at first. But, I have seen various sales and low price points over the last 10 years. Average price seems to be stable at about $2,000 with occasional sale prices down to $1,600. A good AR15 like a Colt or FNH runs anywhere between $1,000 -$1,400. With premier makers like LWRCi closer to $3,000. A Steyr Aug at $2,000 or less is a reasonable price. And, even though they look complicated. it doesn't take long at all to completely become familiar with them.
