"In the early 1980s, the Austrian military decided to acquire a new duty pistol asking numerous famous local and foreign weapon manufacturers for their bids. Due to GLOCK‘s excellent reputation with previous military contracts, GLOCK was also invited to bid on this new contract. This was a new challenge for the company, since pistols were not in its product line at that time." From the Glock company‘s web site. The Glock 17 was eventually chosen for the Austrian Army. This is a handgun which was designed from the outset to "military" specifications. Hence the lack of external safeties (Beretta, Browning, etc.) or de-cocking levers (Sig Sauer), etc... The Browning Hi-Power is an excellent handgun and functions nicely, however, it is showing its age. The Sig Sauer series of pistols is also excellent (among my personal favourites, check out the new .375 Sig calibre products) and they are replacing the Brownings.
Logistics and fiscal realities aside. There are a few new models to consider: The FN five-seven is an interesting newcomer. It‘s a companion to the FN P90 sub-machinegun. Both use the 5.7x28mm round. Flat trajectory, low recoil, serious penetration. Odd looking pistol, but who cares? I‘m curious about the H&K USP‘s. Seem to be a good line with potential.
As for my personal favs (thought I‘d add my 2 cents). I‘ll take a customized Para Ordanance P-14 .45ACP. Call me a purist, by I still like a good single-action .45.
