If I remember correctly, it serves both as a manufacturer's emblem and a proof mark that it's been inspected and approved for retail sale.
One is on the trigger
Yes and no. The Glock does not have an external safety that is operated by the shooter. The safety mechanisms are controlled by the trigger, and function when the trigger is pulled. If the trigger is NOT pulled, the safety mechanisms prevent the firing pin from moving forward and striking the cartridge. However, if a Glock has a cartridge chambered, AND you pull the trigger, the gun WILL fire.
None of them have traditional safeties. They just have the trigger block mechanism.
The Glock trigger can be adjusted by internal parts. The part most used is the connector. These come in 3.5 lb, 5 lb, and 8 lb. Aftermarket parts may add more variables.
Not without some work by a gunsmith.
Yes, the frames are exactly the same. However, various parts would need to be swapped out such as the trigger housing w/ejector as that item is caliber specific. The trigger assembly may also have to be swapped out as the models vary by caliber also.
The Glock 34 is a 9mm pistol. It has a 5.32" barrel (which is 0.82" longer than the Glock 17) and a longer slide, extended magazine and slide releases with a reduced trigger pull. The longer slide gives quicker recovery between each shot.
Glock's are for the most part, NOT automatic. They are SEMI-Automatic which means that each time the trigger is pulled, the firearm discharges one round. There are a few (most aren't in the US) Glock Model 18's that are what is know as "select fire" models. These models allow the user to select between semi auto mode and full auto mode. Fully automatic fire is when the trigger is depressed, the firearm discharges ammunition at a certain rate until either the mag- azine is empty, or the trigger is released.
Glock pistols use an internal http://www.answers.com/topic/safety-firearms mechanism with three components, with no external thumb activated safety switch as might be found on traditional-design pistols. Glock calls this the "http://www.answers.com/topic/safe-action" system. All three safeties are disabled one after the other when the trigger is depressed. They are: * http://www.answers.com/topic/trigger-firearms Safety: An external http://www.answers.com/topic/lever mechanism contained within the trigger that prevents the trigger from moving unless the lever is depressed. * Striker Safety: A spring-loaded pin attached by an extension bar to the trigger assembly blocks the striker from striking the http://www.answers.com/topic/percussion-cap of the http://www.answers.com/topic/cartridge-firearms until the trigger is pulled. * Drop Safety: The far end of the same extension bar locks the striker into place from the rear until the trigger is pulled. These features apply to all GLOCK pistols.
Yes, it will fit, but the barrel will not go all the way to the bottom of the holster. Depending on the holster, it may or may not make a difference.
Due to the polygonal rifling in Glock barrels they recommend FMJ bullets. FMJ generally does not cover the bottom side of the bullet. TMJ covers fully. You can shoot either FMJ or TMJ through a Glock.
Glock 17, Glock 18, Glock 19, Glock 26, Glock 34, and, if you count the 9x17/.380 ACP in this running, the Glock 25 and Glock 28.
