Glock
Glock has been the only semi auto pistol I've owned that was inexpensive, utterly reliable with all ammo, extremely low maintenance, easily cleaned, some models are "sized" as well for carry as anything, Light weight, have slimmer grips and higher capacity in 9mm & 40mm than most, conceals very well, most durable finish available, retains a higher percentage of value than most pistols, extremely accurate ( but hard to capitalize on due to trigger), comes with excellent sights, has no weak points. In my opinion, at a very low cost, Glock will put you in the top 1/100 percent of measurable performance in any catagory of any pistol ever made. I love the 1911 platform but have had only one that approached my Glocks for reliability. I have two custom 1911's valued at about $5,000 and I carry a Glock 23. I feel I'm better armed with the Glock, however I shoot the .45's for the trigger and ambiance. Are they better guns? The sad answer is no. I have owned well over a 100 pistols for comparison. The only major brand I can think of I haven't owned is the H&K. I trade around a lot and usually have 4-5 pistols around. In my opinion the Glock 19 & 23 are top of the defensive handgun world even after all these years. They are not just good guns, they are great guns. However, they are ugly plastic guns.
