I found and purchased an older Gen3 G17. I checked the serial number and I believe it was manufactured around April 2005. I field stripped and dry fired it a few times with snap caps and took it to the range. Everything went well. Didn't have any issues. It performed like everyone says it should. This is my 2nd pistol purchase and my first Glock. As far as I can tell, this gun is completely stock all the way up to and including the sights. I only put 100 rounds through it today, but I have no complaints.
I've read about people buying used Glocks and tacking/sending them to the plant in Georgia, if I take this action what are they likely to do, what is the benefit? I'm looking for advice, as a first time Glock owner, on how to move forward. Just because there are a bazillion aftermarket parts for these things I see know reason to randomly spend money just for fun. This gun will be used for concealed carry and home defense and that is how I want it set up. I want to place a premium on reliability and durability and stick with OE parts whenever possible.
So, for all you Glockperts, what works with these guns and what doesn't?
Thanks in advance.
