Back in my youth, I owned and fired quite a few handguns, and entered into several IPSC events, although I tried to commit myself mostly to the three gun events. Some of those American pistoleros were very, very good.
My own weapon was a customised Browning HP, complete with two barrels (from the factory), Pachmyer grips, three dot sights, ambidextrous safety, and some more stuff. I never once had a stoppage, which is a good thing, shooting minor caliber was difficult enough.
I liked the Sig 226, although it didn't have the "feel" (balance)I liked, but that can be gotten used to quite easily. The Glock, I would sooner leave alone, thanks. Maybe it was just the early ones (I did my shooting in the 70's and 80's), but lots of stoppages and breaks started occuring with the Glock owners after about 10,000 rounds down range.
If I was to carry concealed today, I would still consider the BHP, but would most likely take the Para Ordinance 9mm.
What was the POS Sig? The 225? Memory failing again.............
