Ah, yes – Glock, the pistol for the lazy man.  Physical and intellectual sloth over a lifesaving tool isn't exactly a virtue.

The Glock pistols are a concession to the unfortunate tendencies of modern military training, where it's cheaper to provide soldiers with the most "idiot-proof" equipment available because it costs less to provide simple equipment than it does to train soldiers.
As a military weapon (original market), I don't have any quarrels.  It does as it's designed.
As a sporting weapon or simply a 'toy' the Glocks do a fine job.  Unless you're a reloader; they then force you to spend another Franklin or more buying a decent barrel.
I'll even extend a passing score to them for personal concealed carry and such.

But.

As a visible, accessible LE duty firearm, they are actually worse than revolvers – anyone gaining control of your service revolver can only shoot you 6 times!  Don't even start to hand me the standard crap about 'no one is ever gonna get your sidearm' ... it's BS.  It can happen.  It does happen.
I'm a dedicated cocked-and-locked guy, but I realize that this is not the ideal system for LE officers, either.  The 1911 and GP-35 (Hi-Power) platforms were designed for combat, and they excel in their intended arena.
What, then?  My recommendations usually center around one of the 'traditional' S&W autopistols. 
  * No "Kaboom", none of the time (all S&Ws I'm referring to have barrels that fully support case heads).
  * They're all cast-bullet friendly without replacing barrels.
  * They don't have self-jettisoning plastic front sights that fall off if the pistol bumps against a carpeted doorframe.
  * Their magazines all drop free without having to resort to an encyclopedia to ID the correct mag.
  * Their magazines are caliber- and pistol-specific to prevent trying to shoot the wrong ammo.
  * You don't need a super-secret Corn Flakes decoder ring to determine if the pistol in question has been back for all its 397 stealth upgrades and changes.
  * And they have two things that will absolutely save your life if you find yourself in a fight for possession or control of the pistol:
  ** a positive mechanical safety, and
  ** a magazine disconnect.
Contrary to pronouncements from fat-butted bureaucrats who dictate policies, the positive mechanical safety is no liability.  Operating it is simply a matter of training (Oh – there's the problem!  Training requires time and dedication and costs money … to hell with that!). 
I've been a 1911/BHP user for 30 or so years.  As any dedicated users know, the safety on this type of pistol must be completely and unconsciously automatic or you will put holes in stuff you didn't want holed.  Training … dedication … I can't even use another type of autopistol in 'action' matches and such, because there's not a safety where I'm expecting to find one – I can't make the pistol fire without a complete stop-and-figure-it-out.  Operating the safety on a SA/DA pistol is no different.  Just like any other piece of equipment, if you have to think about how to operate it in an emergency, it ain't gonna happen.
The magazine disconnect is another life-saving device.  Any struggle for the pistol should result in the officer punching the mag release button and dropping the pistol.  It is now suitable only for a paperweight or a rather inefficient bludgeon.  Unless you're brainless (or work for one of those anal departments that prohibit back-up weapons), you have another weapon close at hand.  Oh, sorry – we're back to that annoying training stuff again.

One last thing to head off most of the irate knee-jerk reaction.  I have family, friends, acquaintances, and customers who are cops.  I'm not anti-cop, goofball, I'd just as soon see them all come home safely.  That starts with the correct equipment and training.

Para Ordnance LDA Tac- Four / 12 plus 1 45ACP

Glock...self decocking, double action, simple to maintain and very long lived.

Sig...DAK offers a double action that is manageable.  Grip size is quite large and excludes significant numbers of the adult population for fit and safe use.

Springfield...a single action pistol that has to be fully cocked when loaded.  Essential that it has a grip safety, as unlike other single action pistols, it does not have a thumb (manual) safety.  Some stoppage clearing techniques will not work with this pistol.  Scant holds can result in a pistol that is out of battery, loaded and cannot be unloaded.

Beretta...put themselves out of serious consideration in the LE market.  Recent Federal experience has not been good.  A senior member of a Federal agencies pistol acquisition board stated that "..we won't be at the Beretta table ever again."

Kimber...has stated that the LE market is only 3% or less of their sales and not significant.  Find out, if you can, why Denver PD took Kimber off their allowed list of duty guns.

My department just did an extensive test of all available "law enforcement" pistols currently on the market.  We evaluated .40 S&W only, and found that the top two (in our opinion)were the Glock 22 and the Springfield XD.  The Springfield has a really nice trigger, however, there was alot of concern with the grip safety.  The Glock is the way to go.  It is essentially a point and shoot type weapon that is easy to maintain.

Ruger gets my vote.  It is utterly reliable, very accurate, cheaper than most and of some importance with all the outsourcing of jobs all rugers are made in America.  Our local police academy has 10 Ruger P-89's each one has been fired at least 30,000 rounds.  Last year we sent two back to Ruger thinking they were broken, one actually did break a small part the other just needed to be cleaned better.  Ruger fixed them both and charged us nothing.  They are still very accurate.  Good pistol, good price and made in America.

Please choose the one you carry or would carry.
