Buying used firearms and starting over
There is nothing wrong with buying used firearms. Some of the best deals you will ever get on handguns are used police trade ins. In recent years, buying a used Glock can save you $100-$200 dollars and if you factor in how much magazines cost, you can get a very good condition firearm and 5-8 gun magazines for the cost of just a new firearm which might only come with 1 or 2 mags. There are now 4 generations of Glocks out there, but I really don’t have a preference. If you like Glocks and the unique grip angle and your looking to enter into gun ownership of one, buy a used one.
If you happen to have one that you either A. wear it out B. got one with a shot out barrel you can start over by replacing the Glock gun parts. I suggest looking up Glock disassemble on youtube or get a Glock Armorers video to replace the smaller parts, but replacing barrels is as easy as clicking your fingers. Glock barrels will run you $100-$200 in general and if you are fortunate enough to have worn one out. I think wearing out a gun is an honorable as wearing out the frets on your Fender Bass, it’s a badge of honor.
