2 pin or 3 pin Glock?

[locosway]

I just bought a G20 and I want the extended slide release but I don't know if I have a 2 or 3 pin model. Can anyone enlighten me on this subject as google has failed me.

2/3 pin

Lay your Glock on its right side. There is a trigger housing pin near the rear of the frame below the slide, thats 1 pin. Look at the trigger, if there only 1 pin that is the trigger pin and you have a 2 pin gun. If there are 2 pins the upper pin nearer the slide is the locking block pin and you got a 3 pin Glock. Either way you got a fine handgun. enjoy.

Looks like 3 pin, there's one all the way near the backstrap and then two for the trigger group.

i thought the only model with 2 pins is the 9mm

early-2nd gen .40S&W and .357SIG Glocks had two pins.
2.5 gen and 3rd gen = three pins for all calibers.

I have a G34 2.5 gen with 2 pins.

All serials match too.

My gen3 G34 is a 3 pin model....

Dude it's a Glock, not a 1913 production Colt or 1938 production Luger...

Nobody cares if the serial numbers match.

it's a 3 pin IIRC...

I was not noting it as something special. I was just stating that the serials match because it is a factory 2 pin 2.5 gen G34.

...and If I am buying a Glock used I do want the serials to match. If they don't match I want to know why. More for historical reasons on use, wear, etc.

I agree with PLINK. If I am looking at a used gun and the manufacturer took the time to serialize all of the parts, I will be examining for it. In particular, I would check that the barrel matches the frame.
