I have followed the thread from the beginning, trying to see where it goes.
I restrained myself of posting in this king of thread because i did not have a Glock, to make my opinion with certain value.
I would say the race is not fair for Colt since they lack of models-calibers comparing the two others brands, besides Glock and Sig the don't do revolvers.
Now the war of candies, Sig mow has the strategy of flowing the market like spray and prey and let see what stay solid from 22 cal. to AR in all formats of firearms available at salty prices.
Now and since the US armed forces accepted their proposal, they are ride on pride so their prices, are they bad at all, they have solid lemons for sure, rapidly remove from market via distributors (e.g.: some barrels paint were horrendous, ask me why, unsafe strike fire pistols and others beans.)
Glock, well a happy owners (neglected for years saying I don't need one, silly me I know) let me clarify.
I don't have low end nor unreliable firearm I consider firearms as small machine that in order to performs correctly need fulfill some requirements as a piece of engineering.
Gaston Glock, get mostly correct from the beginning several items, market, quality, price, fixed the quirks of some models and calibers, distribution channels.
Now my beans, Gaston said to the world forget about carry an anvil and try mine, at the same time he explained to buyers forget about decockers, frame safeties, slide safeties and so on for unneeded options (40 years later we are buying pitols with decockers and safeties ala S&W 80's tell the US Army) I got it right, cheap and easy.
I am a happy owners of a model 17 with an overall good performance, I have many Sigs none of them are polymer though, their models film gummy in my hand.
Can I compare Glocks to Sigs, yes some models are equivalents so apple with apples.
Glock are cheaper, same mags for caliber, more aftermarket parts and accessories and their customer service were there when Sig you have to send 20 emails and calls.
From the comfort zone I would say Glock 17 more than the 19 won the small battle and does yet, let see in 5 years how Sig they treat us.
Having Glocks, CZ P10 (needs heavy bullets to shoot where you aim), XD and HK VP9 one of the best now and several others brands, if you don't care about others options Glocks sound good.
