Can anyone tell me how to identify what year the gun was made, so I don't buy one several years old, gen 3, and gen4.

Thanks, Mark

If it's new in box, why should it matter if it's a couple of years old?

The main difference between gen3 and gen4 is that gen4 has additional backstraps that will change the size of the grip.

The other thing is the Gen 4 just came out less than a year ago (Maybe a little more than a year?) So you won't come across any gen 4s that are too old. As far as a gen 3 goes, I wouldn't worry about age. If you buy new, don't worry AT ALL. If you are buying used, I would try and shoot it before you buy it but if everything seems good then go for it.

As to your question, I don't know if there is a way. You might be able to call Glock and give them the serial number and they might check for you. I don't know. Good Luck!
