Striker-fired pistols

Well, I've had a Glock 22 cocked/loaded 99.9% of the time for the past 10 years or so. Never had any problems. YMMV.

are they safe to leave cocked for extended periods of time? something about holding a piece of steel back spring loaded as the 'hammer' is making me question whether or not they are alright

Yessir they are. Technically they are not "cocked" ever, and there is not a "hammer" per say. They are double action only, meaning that the first portion of the trigger pull is actually cocking the striker back. The last part of the trigger pull breaks the striker free and drops it forward.

Essentially, this design is made to keep one in the chamber at all times. Striker fired guns like Glock and Khar autos can be dropped out of a car on the freeway and will most likely not fire.

As already noted, your Sigma, Glock, Kahr, etc. is not really cocked at all when it is loaded.

Only when you pull the trigger is the striker fully cocked and released to fire the round.

The Springfield XD is the only modern pistol that comes to mind that is truly fully cocked all the time. And it can't possibly fire unless the trigger is pulled fully to the rear to release the firing pin safety.

Incorrect, at least as it pertains to the Taurus 24/7. The 24/7 is SA/DA and striker fired.

Thats why I bought a Glock.

Most striker-fired pistols are only "semi-cocked" anyway. For the ones that are not, holding a spring in full compression all the time is not going to hurt anything, within reason.

no issues here, with glock,xd's and others. they are fine and will be fine.

HK warns users to not keep their striker-fired pistols cocked for extended periods of time.

FN P series.

The Springfield XD is NOT a DAO. It is a single action pistol. When the slide is racked, the striker is fully "cocked."

I have a Glock 19 that has stayed cocked (or is that 1/2 cocked?) for a decade and have never had an issue. Same thing with a buddy's Glock 23 for the last 5 years. None of his fellow officers have mentioned an issue either.

Hardly scientific but perhaps helpful

good luck

One of the reasons you won't see SA providing or selling any factory cutaway models.

Don't forget the S&W M&P, which is quite simple to evaluate with the pistol field stripped. Note that the trigger bar moves the sear, which releases the cocked firing pin.
