IMO, if one finds a gun with a manual safety to be too "complicated" to use, he/she has no business shooting guns period (regradless of whether he/she is a "noob"). Inability to perform a simple finger movement necessary to lower a safety lever is a sign of either severe physical handicap or extreme mental retardation.
Took the IPSC course recently. 95% were using guns WITHOUT safeties on them. In fact, I was the ONLY one in the course using a gun with a safety and the reason is simple... it slows you down at first and takes some getting used to. Pity.
The Glock's claim to fame is simple. It works all the time and is ultra reliable. It was designed and is designed for one purpose... close quarters combat and being carried in a tactical or duty holster.
Anyone that carries a Glock in any other manner is playing with fire if they carry chambered, as far as I am concerned they are cocked and UNLOCKED with one in the tube. Period. Don't care what the BATFE or anyone else has decided (partially cocked single action? Jeez).
Having said that, we own several Glocks. Why? Because they are loads of fun and are very reliable. They take one hell of a beating and keep on ticking.
When I shoot IPSC, I have started with the Glock 35 but had trouble getting the magazines to fall (that mag release is crazy). My shots were all over the place. As a last moment decision, decided to go to the Para P1640 (which has a pain in the butt thumb safety). My shots are all "A"\s now but I have to practice that thumb safety thingy a whole lot more as it tosses some time onto my shooting. I think it's worth it. Big difference in accuracy and I believe the Para is ALMOST as reliable as a striker fired pistol. I love it. Them.
Glock was also designed to be high capacity, which the LEO's of the world appreciate. Better to have a couple of mags with thirty plus rounds on your hip than a couple of mags with 16 rounds.
Glocks are also simple guns with less moving parts than most other handguns; easier to break down and work on. Easier to break down for the 'master cleaning'. And they work dry. Wasn't it a Glock that they ran 50,000 rounds through without cleaning or oiling?
Etc. Etc. Everyone should own at least ONE Glock. After that you can get serious.
BTW, I never met a Kimber I didn't like, even if they are not 'bet your life' reliable. I don't think I would use on in IPSC but one never knows. I have four of them. Two reliable and two ... well, not UNreliable, but they do jam occasionally (albeit rarely) and for me, even once in a while aggravates the heck out of me, especially if I cannot tap, rack and fire again.
